いくつかの評価プチプラファッションの品名を持つとあるwebでの通販が好きで可愛らしく利用するぼく。お手頃予算なのに盛装でキレイ目にもカジュアルにも着れて只今っぽくて、こちらの衣料はしょっちゅうヘビロテだ。それでも、寸法感じなど微妙に気になるブリーフなどの衣料は実職場をめぐって着てみてから購入することも多いのです。
昨今めずらしく携帯を持っていないぼく。通販はそのままPCで。それでその品名の会員登録はPCでしていてスマホではしていないので、実職場で買い物をすると構成がつかないとあきらめていました。
そんな時、その品名のメールオーダーサイトを見ていて発見してしまいました。webのマイページからバーコードを印刷してそれを職場で買い物の際に取り出したら構成が溜まるについてを…。ひえ～！時節の変わり目でこういうはじめか月その品名の実職場でかなりの買い物をしたのに、総合捨てていたなんてぇ…。諦めきれずに不可能根源でその品名のwebに構成の復路付が出来ないか問い合わせてみました。
そうなると親切にも最近のものであれば受領証に記載されている番号などの詳細をメルアドで案内したら特別に復路付していただけるというお返信?すっと最近の買い物で構成をつけていなかった分を報告して待つ事件数日。webを確認してみたらじっと構成がついていました。
ありがと～?これからもまたこういう品名のみお買いもの行なうっ！こちらへ

Living in China isn't all that bad. But in FUzhou the summers will boil you. But never fear....

There are spots all around in the mountains which provide GREAT relief. Check it out yo. I'll be posting my tour of the Fuzhou mountain areas, roads, swimming holes .......

Creating buildings and checking house numbers

2016-12-20T04:02:25+00:00

If you haven't checked OSM in the last few months, you'll be surprised to see that many houses (and buildings) have been added in Kamloops. - I did most houses on the North Shore - I completed Sun Rivers - I finished Juniper - I just finished Valleyview

Since many people are now using Maps.me in order to add POIs, having the buildings ready makes the operation very easy.

Gedling Church Panorama #2

2016-12-19T23:37:27+00:00

My September diary entry contained a view from near the top of Marshall Hill, looking north down the length of Chatsworth Avenue at the spire of All Hallows Church in the middle distance (All Hallows is the CoE parish-church for Gedling village). I believe that that was my first photo of that church spire.

My mapping since September seems to have taken me in a clockwise-rotation around the spire, and I am now approaching the church from the west.

Most householders do not like having photos taken of their homes, and I try my very best to respect that. At the same time, I know that panoramic shots of a district are one of the best ways to allow strangers to get a feel for an area, and I do my best to include such shots if I'm lucky enough to come across one.

Below is, I believe, only the 2nd shot that I've taken of the Gedling Spire. It is at a very similar distance to the first (as listed at top), but this time looking east from a walk at the top of Linby Close:—

Exemple de Contribution à OSM accessible aux débutants

2016-12-19T21:15:22+00:00

Il s'agit "d'amener OSM" chez tout le monde. C'est à dire de ne plus laisser de maison sans route à proximité Ce sont des contributions simples il suffit en général de rajouter un chemin en s'inspirant des données du cadastre et de l'BDOrtho IGN

1- détection se rendre sur : http://tile.openstreetmap.fr/~cquest/leaflet/bano.html#9/43.8216/1.4227

laisser le rendu par défaut mais cocher 'QA' zones à compléter à l'aide du menu en haut à droite de la page web

2- le but est de guérir de cette rougeole chaque tache rose correspondant à un carreau d'1 hectare ou l'INSEE a recensé des résidents mais sans pour autant qu'il y a de chemin y arrivant (c'est probablement le signe d'une route manquante dans OSM)

3- repérer le secteur à corriger puis ajouter le highway (chemin) manquant avec votre éditeur préféré vous avez le bouton en bas à droite pour travailler directement dans votre éditeur préféré

les symptomes disparaitront (le carré rose disparaitra) lors du controle suivant (délai de qqes jours)

supplément : il y a une maladie similaire (signalée en bleu cyan au lieu du rose précédent) présence de population dans un carreau mais absence de batiment (c'est probablement le signe d'un batimant manquant dans OSM) il faut rajouter le 'building' manquant cependant si beaucoup de bati manque sur une même commune, la tâche d'import du bâti n'est pas recommandée pour quelqu'un qui est un apprenti contributeur

Routenplanung — Verkehrskreisel

2016-12-19T14:26:45+00:00

Ein kurzer Einblick in den junction=circular Tag.

Verkehrskreisel sind eine moderne Art von Kreuzungen. Bei der Routenplanung unterscheiden wir zwischen Kreisverkehr Kreuzungen, benannten und unbenannten Kreisverkehren. Kreisverkehr Kreuzungen sind dabei ein Spezialfall von Kreisverkehren, die relativ klein sind und bis zu vier gut unterscheidbare Ausfahrten haben.

Damit ein Verkehrskreisel sich einen Kreisverkehr im strikten Sinne der Definition nennen und damit junction=roundabout getaggt werden darf muss er bestimmte Kriterien erfüllen. Einer der wohl wichtigsten Faktoren ist, dass der Verkehr im Kreisverkehr Vorfahrt hat.

Nun gibt es Verkehrskreisel die wie Kreisverkehre aussehen und auch als solche von Mappern getaggt werden, aber tatsächlich keine sind, da sie die Kreisverkehr Kriterien nicht erfüllen.

Ein Beispiel dafür ist der Bersarinplatz in Berlin. Hier hat die B 96a Vorfahrt, was den Bersarinplatz als Kreisverkehr disqualifiziert und ein junction=roundabout nicht angebracht ist. Das steht allerdings im Konflikt mit der Routenplanung bei der Instruktionen wie "Beim Bersarinplatz die zweite Ausfahrt nehmen" gewünscht werden.

Da junction=roundabout nicht angebracht ist, dokumentieren Mapper das Abhandensein meist in Notizen. Dadurch gibt es allerdings keinen Tag mehr, den sich die Routenplanung zu Nutzen machen könnte. Notizen sind unzuverlässige Pseudo-Tags und keine strukturierten Daten.

Ein junction=circular Tag löst dieses Problem: zum Einen erlaubt er es Mappern ein klares Zeichen zu setzen wenn junction=roundabout nicht angebracht ist. Zum Anderen kann der Tag nun bei der Routenplanung in Betracht gezogen werden.

Hier sind die Wiki Seiten der Tags:

Vielen Dank an Tom Pfeifer für das Schreiben der Wiki Seiten und für das Ausprobieren des Tags an Verkehrskreisel in Berlin.

Hier sind Beispiele für junction=circular in Berlin:

Für mehr Details gibt es hier das ursprüngliche Ticket. Verkehrskreisel sind im OSRM v5.5 Release enthalten. Für Feedback zur Routenplannung sind wir im OSRM Repository, im IRC oder auf der osrm-talk Mailingliste anzutreffen.

Routing — circular junctions

2016-12-19T14:23:26+00:00

In which I outline the need for the recent junction=circular tag.

Traffic circles are a modern feature of intersection design. They come in multiple forms and shapes.

OSRM distinguishes between roundabout intersections, named, and unnamed roundabouts. Roundabout intersections are a special case of roundabouts that are small and offer up to four clearly distinguishable exits.

To be considered a roundabout in the strict sense the road junction has to follow certain criteria. One of the criteria for a roundabout is that traffic in the roundabout has the right of way.

There are circular junctions which may look like and be commonly identified as roundabouts, but they are not roundabouts because they do not fulfill all of the criteria for being a roundabout.

For example, traffic in the roundabout at Bersarinplatz in Berlin has to give way to incoming traffic on B 96a, disqualifying it as a roundabout. This is in conflict with the desire to provide instructions of the form "use the second exit" from a navigation engine.

Since a junction=roundabout tag is not appropriate, mappers will often document the intentional absence of any roundabout tag on these junctions using notes. This approach means however these junctions will not be tagged in a way that lets routing engines distinguish them from non-roundabout roads.

Notes are only an unreliable pseudo-tag, however, and don't provide any clear structured data. A junction=circular tag properly documents the mappers intent and makes it possible for routing engines to handle.

Check out the tags' Wiki pages for more detailed descriptions:

Thanks to Tom Pfeifer for pushing this endeavor forward, writing up the Wiki pages and tagging circular junctions in Berlin.

Here are some more examples of junction=circular tags in use:

Evaluation of participatory transport mapping data: MapatónCDMX

2016-12-19T04:43:58+00:00

Why evaluate?

OpenStreetMap is an international community of citizens who are experts in open geographical data, from different perspectives and specialties, and in methods of collaborative construction of information. OpenStreetMap is part of the trend of Voluntary Geographic Information.

The Mexican community of OpenStreetMap is mainly involved in 3 lines of action:

Strengthening the community (training and methodological support in projects, integration with academia and activism)
Procedures with government institutions for the importation of large public databases
Management with institutions to promote open and collaborative practices in its information management

As a community and ecosystem of technologies, OpenStreetMap has participated last years in several initiatives of participatory mapping of informal transport. This lack of good transport systems, and lack of data is crucial in developing cities.

Objectives of transport mapping initiatives

These operations usually pretend to:

Create a complete transport system map to allow citizens to orient themselves in their city and make their mobility more efficient. Having this map allows more people to use collective transport instead of individual transport, with important implications on the mobility system, economy, environmental conditions and the quality of life of people
Provide local governments with data to regulate their transport, when they do not exist in useful formats
Provide city and transportation planners with the necessary information to generate diagnostics, analysis, and design
Allow research and innovation on the subject of transport and mobility with georeferenced open data and with quality standards

In order to make it possible for organizations, communities and governments to systematize the different experiences already developed in the world, the OpenStreetMap Mexico group undertook a medium-term exercise in collaboration with WRI and MIT to document all cases, evaluating, and highlighting successful practices in terms of organization, management, participatory method, technology, data produced, socialization and outputs given to the data, as well as the methods used to be able to update them. The result may be in the future a platform that catalyzes and shares knowledge: where in addition to providing the open technologies and data generated in different cities, a methodological guide is shared with the methods that have led to the best results.

The experiences developed in the world - Mapanica in Managua, Matatus in Nairobi for the best known, but also in Egypt, India, Bangladesh, Colombia, Mexico, etc. Have been led by different organizations, usually in an horizontal collaboration: associations, NGOs, communities such as OpenStreetMap, groups of civic technologies, universities, small businesses or startups, local governments.

This text is the first step of an evaluation work line of participatory transport mapping operations. This first evaluation is about the final data of MapatonCDMX developed in Mexico City.

Guidelines on the work process of MapatónCDMX

The results presented are from the MapatonCDMX organized in 2015-2016 by the "Laboratorio para la Ciudad", the area of innovation of the Government of Mexico City. The Laboratory proposed to develop a methodology and participatory dynamics to carry out mapping on a voluntary basis.

The MapatonCDMX was initially developed based on a working method applied before in Mexico City and other countries (Bangladesh among others) by the organization Urban Launchpad with the app Flock Tracker. The strategy changed in the course to incline towards the development of an application proprietary for the track of the transport routes, with essentially the same methodology.

In parallel, a collaborative table was formed with participants from various profiles and institutions. The OpenStreetMap group had the opportunity to participate in some working meetings where we suggested the use of existing open technologies instead of developing an app from zero, and to provide in the information structure the necessary attributes to the later generation of GTFS **.

The participatory dynamics was directed towards methods of gamification, based on an open call and the formation of teams put in competition for the obtaining of sponsors' prices. To improve participation, other groups of young people already enrolled in a voluntary process (INJUVE youth) were added to the dynamic. The organizations represented at the collaborative table were also asked to contribute with the provision of volunteers.

The data collection season resulted in a data set that was subsequently cleaned with the contribution of several organisms, in 2 stages, with a relative result.

MapatonCDMX data evaluation

The data of the MapatonCDMX were published in different formats, the files of the GTFS specification can be downloaded here, the complete database can be consulted from its dashboard and API for developers.

The first public delivery of data via the API, yielded a route system with topology deficiencies and an erroneous validation process.

Photo 1. Routes contained in the API of the MapatonCDMX in the first delivery

In the Mapaton API, which was the method for public consultation and download of routes in GTFS format in the first delivery, 2893 routes were available, of which only 501 were valid for GTFS format, representing only 20% usable in navigation and network analysis technologies.

Photo 2. Routes contained in the GTFS in the first delivery

The routes contained in the GTFS, despite having a good topology, did not manage to be representative of the public transport offer in the CDMX. The state of the information requires a process of validation and correction of the routes contained in the API that could not be integrated to the GTFS because of the topological errors.

The data were submitted to a second cleaning session with the support of the Mario Molina Center in October and November 2016. These data were made available in December. In this second stage, the API presents 4019 routes, of which 29 do not contain geographical information, the 3990 remaining routes are divided into categories:

Valid: 2162
Invalid: 1122
Invalid, out of time travel: 529
Invalid, data with error: 177

Of these routes, 501 were finally added in the GTFS format, which represents 23.17% of the total of API's valid routes. For these 501 routes, georeferencing is good and is attached to the road network, but some of the attribute information is missing and does not allow to validate the format and give it a possible use: service schedule, stops, time of arrival at stops. When this information can not be reliably robust (such as in the case of informal or unstructured transport systems mapping), the construction of a GTFS format relies on estimations, but information can not be dispensed with.

A visual summary of the information contained in the GTFS is presented:

Photo 3. Routes total Photo 4. Valid routes Photo 5. Invalid routes Photo 6. Invalid routes, short travels Photo 7. Invalid routes, travels out of time

As synthesis

The current MapatonCDMX data has a very low part of valid strokes and the absence of the complementary attributes don't allow its use as a GTFS. For this purpose, this data may still go through an in-depth process of validation and correction, which could be done with some technological tool or with a crowdsourcing methodology, which should be submitted to a cost-benefit evaluation. Another strategy could be to re-raise the data or establish a permanent mechanism for contributing to the create new data over a long period, to progressively replace non-functional information.

Because of the scope it has had, the MapatonCDMX can be seen as a pilot test of cooperation, and methods of citizen participation. We invite you to read soon about the methods and results of other non-structured transport mapping operations carried out in other cities around the world. We will inform about the upcoming evaluations in this blog and networks of OpenStreetMap México.

** The General Transit Feed Specification (GTFS) was created in 2005 by Trimet and Google so that transit agencies could share open information in a simple way, boost the technology development ecosystem and facilitate the development of applications that use this information.

OpenStreetMap UK Local Chapter officially exists

2016-12-18T16:01:12+00:00

On Saturday morning I received from Companies House the Certicifate of Incorporation for OpenStreetMap United Kingdom Community Interest Company Ltd. It is a private limited company, limited by guarantee.

It’s taken us a year to get this far, through a protracted and often tedious process of agreeing Memorandum and Articles of Association,Community Interest Statement, form-filling, and signature gathering. Thankyou to everyone who participated, especially the volunteers who agreed to be the first directors necessary to get the thing off the ground.

Now we can start doing the fun stuff of how we make this work and transform it into a living organisation.(Although I’m sure we’ll still have our share of bureaucratic process to navigate).

Using Osmose to fix admin boundary errors

2016-12-18T15:23:30+00:00

Over the past few days I have been using Osmose (docs) to find errors in administrative polygons in Ireland. OpenStreetMap does not have a native area type, so we have to create type=boundary relations. It's easy to break these areas, which means software which wants to extract boundary data from OSM is unable to "see" these areas.

As someone who consumes OSM data for administrative boundaries (Townlands.ie for townlands in Ireland), I have a certain affinity for admin boundaries in OSM in Ireland, and would like T.ie to be as good as possible, and that's possible if the OSM data is the best possible.

I've been turning off all checks in Osmose and enabling just the open polygon error. Click on each blue marker to open the popup with details. Then click the "josm" link for the relation with the problem, which will load that relation in JOSM using JOSM's remote control. The JOSM validator will then tell you where the open polygon is. You should then look at the problem and see what's wrong and how to fix it. The most common error is a small gap, and there's a missing way that you need to (re-)add to the relation. However I have seen more complicated errors sometimes.

Osmose will update regularly, but it can take a day before it's updated, so the "polygon error" will still be on the website. You can click on the "corrected" link in the popup to tell Osmose that this problem has been fixed. The popup & marker will then disappear from the map (for everyone). You can then clear the errors and work on the next problem. Sometimes I've seen many copies of the same error on top of each other, so if you click "corrected" and it looks like the popup & marker don't disappear, it probably did get recorded as corrected, it's just that there's an identical error in the same place which you're seeing. Just click "corrected" on all of them until it goes away.

Why OpenStreetMap US elections should use Single Transferable Vote (STV)

2016-12-18T07:21:49+00:00

Today is the final day of the board elections for the US chapter of OpenStreetMap (OSM-US). Just a few days ago the international OpenStreetMap Foundation (OSMF) also held its elections. If you are a member of both groups, you may have noticed that the two organizations do their elections a bit differently. In OSM-US elections you just choose from a list of candidates, while in OSMF elections you rank the candidates in order of preference. What are these two systems, and which one is better? Well, I'm glad you asked...

The international OSM Foundation uses a system called Single Transferable Vote (STV). STV allows voters to rank candidates in order of preference, and produces a proportional result (meaning, for example, that 40% of the voters can choose 40% of the seats on the board). OSMF has been using STV in their last few elections, and Richard Weait wrote some detailed post-mortems of these recent elections, such as OSMF Board Election Results 2015, and the more descriptive OSMF Board Election Data 2014. He has more blog posts on STV here.

OSM-US currently uses a non-proportional Block Voting system (technically, "Plurality-at-large voting") where each voter can choose five candidates, and the candidates with the most votes win. While this voting method is easier to implement, it requires the electorate to vote strategically, rather than expressing their true preferences. Also under this system, there is the potential that 51% of the electorate could choose all five seats on the board.

So which method is better?

STV performs better than Block Voting in a few key ways:

First, voters can express themselves more fully because they rank the candidates from their most favorite to their least favorite. Voters don't have to make arbitrary binary choices of who's in and who's out.

Second, voters can vote sincerely for who they really like the most, without having to guess about whether their preferred candidate has a chance of winning or not. Because your vote transfers to your second choices if your first candidate doesn't win, you don't have to worry about throwing your vote away on "spoiler" candidates. STV lets you vote idealistically without giving up your chance to influence the results.

Third, every group within the electorate has a chance to elect someone who represents their views. Because STV is a proportional system, it's impossible for a slim majority of the voters to dominate the board. The result of STV is a board that represents the full diversity of the OSM community, and is better able to resolve differences and find compromise.

The consensus of all the major non-partisan electoral reform groups (FairVote in the US, FairVote Canada, the Electoral Reform Society in the UK, and so on) is that STV is significantly better than Block Voting. None of these organizations recommend Block Voting, and all of them include STV among their most recommended options.

For these reasons, OSM-US should switch to STV elections before we vote on the next board in 2017.

Ok, but is there actually a problem that we need to fix?

It's true that currently the OSM-US board elections are small, civil, and friendly affairs, and we do not have the concept of political parties and contentious campaigns. Right now with OSM-US our election system isn't causing any significant problems that we can see. The system isn't broken, yet.

In fact, there is a good chance that STV and Block Voting would produce mostly the same results in recent elections. Brandon Liu ran a simulation based on the previous two OSMF elections, and found that Block Voting and STV would have produced the same results.

Why is there little to no difference? Currently we still have a small number of candidates relative to the number of seats (roughly twice as many candidates as seats) and we don't really have strong factions (yet), so the difference between the two systems shouldn't be very noticeable. But we shouldn't be complacent and assume that these the status quo will not change in the future. When factions do emerge in the electorate, we need a system that will respond well to those changes without breaking. We need STV.

Then why should we change?

As OSM keeps growing, we will probably get more candidates, and see more vote splitting and factions forming. Also, if stronger divides in opinion develop within the OSM-US community, we might see board elections that fail to represent the diversity of opinions in the electorate.

The board should be able to resolve conflicts between different factions in the community if and when they develop. To do this, the board needs to include representatives with diverse perspectives. But with block voting, there is the strong likelihood that a minority group would not be able to get any members on the board to advocate for their views.

Imagine if 51% of the electorate wanted to ban imports (just as an example), and 49% did not. If the anti-import group ran a slate of five candidates (a common practice in elections using Block Voting) they could win all the seats under our current rules. The minority would be shut out completely. Under STV, however, the minority faction would be guaranteed some seats on the board.

But STV is also great because it doesn't require party affiliation like other proportional methods do. Voters can choose to rank candidates based on differences in their platforms, or they could allocate their vote based on regional affiliations, or gender, or whatever differences matter to them. STV produces boards that are proportional across whatever dimensions are important to the voters.

Who supports the change?

During the current OSM-US election, I asked each of the eight candidates whether they support a switch to STV or not. All the candidates who were familiar with STV supported it enthusiastically, and the others who hadn't considered the issue before were tentatively supportive. No one strongly supports Block Voting, and the only reason we keep using it is institutional inertia.

Furthermore, the OSM-US bylaws are not prescriptive about the exact method of our elections, so it should be relatively easy for the board to switch to STV elections without any change of the bylaws. Given the apparent consensus of the incoming board members (no matter whoever gets elected), hopefully we can switch to STV before the next elections in 2017.

Even if OSM US doesn't have problems yet, there's inherent value in us using the most democratic voting methods we can, and being a model for best practices of self-governance. OSMF is taking the lead here, by using STV for their elections, and it's time that OSM-US joined them.

True namespace versus Colon-delimited suffix/prefix

2016-12-17T20:07:20+00:00

Thanks to this diary entry, I just discovered a Wiki page Date namespace which exists there since 2014 as an improperly published proposal. Basically, it is about an introduction of syntax that supposedly gives us the ability to indicate a date range for virtually any key. Proposed syntax looks like this:

<key>:<year>-<year>=<value>
<key>:<date>--<date>=<value>
<key>:<year>-=<value>
<key>:-<year>=<value>

Unfortunately, I haven't been aware of this until today, but it's never too late to address it.

First of all, storing a variable value in a form of colon-delimited suffix (or prefix) is not the same as utilizing a namespace because namespace always serves a purpose of grouping. So, this proposal has nothing to do with a namespace.

The second problem is that variable colon-delimited suffix makes data processing awfully redundant. With a proper namespace suffix, it is easy to compare it with a set of known ones within a simple query, while the date "namespace" syntax requires a complex regex (including an ISO 8601 date format pattern) to find all keys containing it. There is no way to "just" select them all because this scheme does not include a qualifier of any kind. Even a bit improved syntax like <key>:daterange<year>-<year>=<value> would allow way simpler preprocessing, but it didn't happen.

You can read more detailed explanations of these two main issues on Talk:Proposed features/Date namespace page.

I am perfectly aware of at least one web service, where developers have managed to utilize this data salad, but it only means that they had enough free time on their hands. Anyone who wants to argue is welcome to start from writing an Overpass Turbo query, showing the names of Irish counties for a specific date (say, 1920) and showing it here in comments.

Townlands.ie supports historic names

2016-12-17T16:32:22+00:00

Townlands.ie now displays the historic name of areas! Townlands.ie is a website which shows the Irish traditional boundaries in OpenStreetMap, like townlands, civil parishes, baronies and counties. It's very useful for Irish genealogical research, and mainting Ireland's heritage into the digital era.

An example of this is County Offaly, which was initially created as a county in 1556 as "King's County", and was known as that until Irish independence in 1922, when it was changed to County Offaly. Neighbouring Co. Laois was known as "Queen's County".

We use the date namespace suffix to support this. The current OSM relation for Co. Offaly shows how to add this data: name:1556--1922=King's County, name:1922--=County Offaly

Townlands.ie currently supports the following 3 forms. Other options may be added later.

name:--YEAR: Name before YEAR
name:YEAR--: Name from YEAR to the present
name:YEAR1--YEAR2: Name between the years YEAR1 and YEAR2

There is already support for adding the name Griffith's Valuation (with name:griffithsvaluation tag), and the 1901 and 1911 census names (name:census1901 and name:census1911). However that is often used for transcription errors.

Please add more historic names to OSM in Ireland!

Filling in the gaps of the maps....Providing a humbler service to humanity...

2016-12-17T10:26:16+00:00

In year 2015, 344 disasters triggered by natural hazards were reported worldwide, affecting 108 countries and nearly 142 million people. That’s 344 times that local communities and organizations, local and national governments, and international organizations needed geographic information on the affected area to inform a rapid and effective response. Unfortunately, there are still many places across the world which lack this basic geographic information, remaining unmapped.

Detailed maps give individuals, organizations and governments’ information to support them in planning DRR activities and preparing for crises. Detailed maps also help humanitarian response actors to get aid where it is needed most, by helping to understand the population size and density, as well as identify and address logistical challenges. Efforts are being made to address the lack of maps in the most neglected places.

Humanitarian OpenStreetMap Team (HOT) is a global NGO that creates and provides digital and print maps to address the world's toughest challenges. In times of crisis and natural disaster, HOT rallies a network of volunteers to rapidly produce maps relied upon by humanitarian relief organizations to reach those in need.

A common question about aid is, does it work? In some cases, yes, but not always. Unfortunately, nothing in life is that straightforward. When someone external comes in to do the work and eventually returns home, they leave with the skills and knowledge of the project as well, so how is this sustainable? We believe initiatives carried out by community members, not only provides local knowledge, which instantly enhances the project, but the skills and knowledge associated with the project remain in the area and continue to be applied.

Micro grants are a way to support local champions of open geo-spatial data (maps), community organizing and an open source software tool chain and building OpenStreetMap from the ground up every step of the way. Many local OSM community builders face obstacles that can be difficult to imagine but they are succeeding in turning OpenStreetMap into a global, open map of the world every day.

Your donation regardless how big or small, is needed urgently to map the world’s most vulnerable and least mapped places through Micro grants, before the next disaster. 100% of each Micro grant donation goes to a local leader who is transforming their country by filling in critical data gaps. Your donation will help provide the basic necessities to these leaders, in the forms of micro-grants. Micro-grants will cover the basic costs of mapping additional villages and cities by paying for things like transportation, equipment, internet, printing, and more.

By contrast with the starry-eyed Silicon Valley evangelists who often claim their technologies have changed the world, we see the process of filling in the gaps of the maps as providing a humbler service to humanity.

“We are not trying to claim that this map is saving a kid’s life. It’s just not true,”

“Doctors, nurses and aid workers save kids’ lives. These maps help them do their jobs better.”

Did you know …

…the first node translated into the language Atikamekw?
… the service MapContrib of Guillaume AMAT? User escada presented it on the basis of a map with dog parks a few months ago.

OSM in the media

The newspaper La Croix published (automatic translation) an article about a contributor, Fabrice Ramamonjy who improves the data of Antananarivo with his community of students. Their university supports (automatic translation) the initiative.

Other “geo” things

An impressive interactive map visualizes the population density of English cities. John Elledge shows some examples on CityMetric.
The detailed replica of the world famous “Lascaux” cave, a Unesco World Heritage Site, was opened by French President Hollande, is now open to visitors.
The change of name from Open Street View to OpenStreetCam is complemented by the new version.
Sightline reports on structural changes in the use of living space in Seattle.
Ivory Coast adds the 3-word global addressing system offered by the British startup What3Words to their own insufficient system of postal addresses. What3Words assigns an arbitrary three-word-code to any 3×3-metres square of the Earth surface. Critics consider it a bad idea to make a postal system dependent on a commercial company’s licensing system.

"O que é o OpenStreetMap?"

2016-12-16T17:15:17+00:00

Reproduzo um trecho de conversa que tive com um amigo sobre o que é o OpenStreetMap.

Essencialmente, o OpenStreetMap é um banco de dados de elementos geométricos (pontos, segmentos de reta, poligonais e polígonos) georreferenciados e elementos lógicos (relações) que representam elementos do mundo real (estradas, rios, construções, pontos de interesse, etc.). As características desses, são atribuídas àqueles elementos por meio de pares chave=valor. Por exemplo, para representar um rio, se usa uma poligonal para representar seu leito e aplica-se o par waterway=river.

Esse banco de dados é licenciado utilizando a Open Database License (ODbL). Porque essa licença? Bem, é uma licença especifica para banco de dados que garante, às pessoas, as liberdades de usar, modificar e compartilhar o banco de dados desde de que mantenham essas liberdades. Repare nessa condição, ela perpetua as liberdades. Essa é a essência do copyleft! Então, a ODbL é uma licença copyleft. Porque isso é importante? Não existe um mágico que tira da cartola um banco de dados com informações do mundo inteiro com uma licença assim, ele precisa ser construído. E como é construído? De maneira colaborativa, num grande bazar (lembra de “A Catedral e o Bazar”?) à semelhança da Wikipédia e do software livre. E para ser construído colaborativamente, são fundamentais essas liberdades. Para modificar, ou só usá-lo, alguém tem que ter compartilhado com você, e não seria justo, com aqueles que contribuíram com a copia compartilhada, se você pudesse restringir essas liberdades ao compartilhar a cópia que obteve ou suas modificações e, geraria incertezas sobre a perenidade da disponibilidade desse banco de dados. Você usufruiu, as outras pessoas também devem usufruir dessas liberdades.

E de onde veem as informações para esse banco de dados? São coletadas em campo, por exemplo, em placas que informam o nome de ruas (e algumas, também, CEP e numeração de lotes), de tracklogs de sistemas de posicionamento, de imagens de satélite, de ortofotos, de leis, etc. Podem ser obtidas, também, de órgãos públicos, de empresas ou qualquer outra fonte com licença compatível com a ODbL. Por exemplo, a Microsoft disponibiliza imagens de satélite para auxiliar o projeto. É importante ressaltar que não se pode usar informações do GoogleMaps, GoogleEarth, mapas impressos, outras fontes comerciais e qualquer fonte que não explicite sua licença. Mas a informação está ali, porque não copiar? Usando informações com licenças incompatíveis, você restringe as liberdades, e pior, contamina qualquer outra modificação feita sobre essas. Com isso, não está ajudando mas, prejudicando o projeto. E expondo-o a riscos de processos judiciais. Pegue o exemplo do rio. Se você obteve a poligonal sobre uma imagem de satélite do google, essa geometria terá que ser removida. Mas e se outra pessoa já tivesse adicionado o nome desse rio usando o par name=Rio Jacuí? O nome é removido junto com a poligonal.

Pragmaticamente, isso tudo produz informações melhores? Bem, a realidade é dinâmica. Empresas comerciais com desenvolvimento no estilo catedral, dificilmente conseguem acompanhar esse dinamismo. Além disso, não se preocupam com o usuário das informações, ao introduzir erros propositais em seus dados. Já imaginou o efeito, na vida das pessoas, de uma informação errada? Dois nomes de ruas trocados de lugar, propositalmente, podem, por exemplo, atrasar um atendimento de emergência... Não da para responder, simplesmente, com um “sim!” essa pergunta. Onde existem pessoas contribuindo, usando, e mantendo as informações, no mínimo, são mais confiáveis. Além de poderem ser utilizadas onde quiser sem as limitações impostas pelas empresas comerciais.

06.12.2016-12.12.2016

Die OpenInfraMap jetzt mit neuen Layern ¹

In eigener Sache

Nach längerer interner Diskussion, wie wir mit dem aktuellen Urteil des Landgerichts Hamburg umgehen sollen und wie wir künftig eine solche detaillierte Linkprüfung durchführen könnten, haben wir uns dazu entschieden, die deutsche Ausgabe der Wochennotiz nach dieser Ausgabe einzustellen.

Mapping

Andy Mabbett schlägt mehrere Ideen für die Quartalsprojekte in England vor. Solltet Ihr ein Interesse an der aktiven Mitarbeit bei der Wiederbelebung der Wochenaufgaben haben, setzt Euch bitte mit dem Wochennotizteam in Verbindung.
Harald Hartmann versucht sich in Mikromapping, was zu einer Diskussion über Flächentagging führt.
Für die Vorschläge zu amenity=baking_oven und oven=* kann jetzt bis zum 20. Dezember abgestimmt werden.
Auf der Mailingliste osm-talk wird über die Benutzung des Tags highway=living_street in Afrika diskutiert.
Alejandro Suárez wundert sich über die unterschiedliche Definition des Tags amenity=bar im Mittelmeerraum und dem Rest der Welt, der wohl durch eine andere Wortbedeutung von bar im Spanischen stammt und würde dies im Wiki gerne vereinheitlichen.
LeTopographeFou stellt fest, dass das eigentlich gewählte Schema shop=estate_agent ignoriert wird und sich stattdessen office=estate_agent durchgesetzt hat.
Daniel Hofmann schreibt über die Anomalien, die die OSRM-Anwender melden, und die Auswirkung von oneway=reversable Tags auf die Routing Engine. Er schlägt das Tag oneway=alternating für die Nutzung in OpenStreetMap vor – eine Diskussion, die auf dem Elbe-Labe-Meeting 2016 begann.
Manoharuss veröffentlicht seine Analyse der MAPS.ME-Edits für November.

Community

Die neue OSM-Damen-Initiative versucht die weiblichen OSMer in einer Telegram-Gruppe zusammen zu bringen.

OpenStreetView review by The Register

2016-12-14T20:18:24+00:00

OpenStreetView? You are no longer hostage to Google's car-driven vision
(14 Dec 2016, The Register)

One of the great bright lights of open-source software and user-driven community projects is OpenStreetMap, which offers an open-source mapping platform similar to, but also very philosophically different than, Google Maps.

This review is about Telenav's OpenStreetView. I find it a little odd, because it mentions OSM at the top of the article (extract above) and also has a link to Mapillary and yet, does not contain a single link to either the topic of the article (OpenStreetView) nor to OSM. Most odd.

Coda:

(with thanks to mmd (see comments)):

The Register review is already well out-of-date as, after OSV attracted the wrong kind of attention from Google, OSV changed it's name to OpenStreetCam on 25 Nov 2016 and can now be found at openstreetcam.org.

Hey I just posted to my diary! Where's the checkbox on this form that says "Share with Twitter" or "Share with Facebook"?

In fact, where the link on this page that says "Provide Feedback on the Diary Feature of OpenStreetMap"?

この記事は OpenStreetMap Advent Calendar 2016 (12/15用) として投稿しました。

OSMstatsから読み解くマッパーコミュニティの現状

About OSMstats

OSMstats は世界中の OpenStreetMap ユーザーコミュニティ活動量が毎日どのように行われているのか、定量的な統計情報を整理して、見える化するサービスです。運営は altogetherlost.com & Pascal Neis (neis-one.org) チームが行っています。

http://osmstats.neis-one.org/

何がわかるの？

様々な情報が可視化されていますが、主に次の情報が便利です。

OpenStreetMapユーザーアカウント総数の時間遷移
日別のアクティブマッパー活動量
国別のアクティブマッパー数

これらの情報を、それぞれ見てみましょう。

OpenStreetMapユーザーアカウント総数の時間遷移

OSMstatsトップページを開く

これは簡単です。OSMstatsのトップページを開くだけです。

http://osmstats.neis-one.org/

Number of registered OSM members

左上の Number of registered OSM members の情報を見ます。2016/12/15 の時点では、3,285,076ユーザーアカウント、約330万マッパーによって今のOpenStreetMapはデータ更新されています。但し、この数字は現時点で有効なアカウント数であり、過去に作ったっきり使われていないアカウントや作業の目的によって複数アカウントを使い分けている人も含まれていますので、実際の人間としてマッパー数はこの数字よりも小さくなります。

グラフの時間軸を少縮尺にする

横軸を時間軸に、縦軸をユーザーアカウント数でプロットした二次元グラフを見てみましょう。また、2012年から現在までの遷移を見てみましょう。

ユーザー数の増加傾向に変化

このグラフをよく見ると、ユーザー数の増加傾向に何度か変化が起きていることが読み取れます。一つは、2012年6月前後からの増加（①）。二つ目は2013年4月前後からの増加（②）、そして最近も 2016年4月からの増加傾向（③）。さあ、ここからその背景を、、、と書きたいところですが、この問いは青山学院大学の古橋ゼミの課題に使うのであえてここでは問題提起のみに留めます。後日学生達の分析を追記公開します。

日別のアクティブマッパー活動量

上記のユーザー増加数の中身を判断するには、実際にマッピングを行っているユーザー数である No. of daily active members overall と比較することが大事です。これは日別のアクティブマッパー数のグラフで、例えば 2016年4月からの増加傾向は、ユーザー数が増えているだけでなく、連動してアクティブマッパー数も同じタイミングで増え始めています。

国別のアクティブマッパー数

最後に、国別のアクティブマッパー数を比較してみましょう。先程までは世界全体の傾向を追っていましたが、OSMstats上に並ぶ Countries タブリンクから表示を切り替えると、各国ごとの集計表が登場します。時差もあるので、２日くらい前に設定したほうが正しく表示されることが多いです。2016/12/14時点では日本は世界でTOP10のポジションにいます。

http://osmstats.neis-one.org/?item=countries&date=14-12-2016 （例： 2016/12/14の集計結果）

今度は、Japan をクリックして、日本のアクティビティ（実際には日本エリア内でのマッパーアクティビティであり、日本人だけでなく遠隔からのアームチェアマッピングも加算されています）を見てみましょう。

日本でも 2016年4月から、アクティブマッパー数が増えているように見えますが、これはグローバルなOpenStreetMapのマッパー数の増加傾向と関連性があるのでしょうか？それとも日本独自の現象でしょうか？いずれにしてもこのような定量的な数値を元に、世界と日本のマッパーコミュニティがどのように変化しているのか、マクロな視点でのコミュニティ分析も大事な見方です。

Tracing guide for Aweil, South Sudan

2016-12-13T15:04:46+00:00

This is a tracing guide for people mapping Aweil in South Sudan for MSF with Missing maps (see the task here). Aweil is the capital city of the state of Northern Bahr el Ghazal. The city's infrastructure is relatively developed. Aweil now has a functioning railway station, hotel, airport, soccer stadium, and public hospital. [1]

As we are mapping the suburbs of Aweil, you will see rather sparse settlement. Here are some photos of the structures that are visible on the satellite imagery. Very detailed information on what MSF is doing in this area, along with many useful photos (some published in this tracing guide) can be found here: One Day in Aweil: An MSF Team Portrait

Residential areas

Residential areas look like this in the idEditor

The houses you are looking for look like this from the ground

[2]

Another photo of Aweil from above

And the last one

Buldings

Houses in this area are usually either traditional African tukuls - round (or square) structures with thatch roof or more solid square buildings with roof from metal.

Other buildings

[3]

How does it look like in the aerial images?

See the huge square building on west of the residential area, and few tukuls (rounded or semi-rounded). South from a tukul in the north-east part of the area, there is a yard - you can see, that unlike buildings, the yard not drop a shadow. As the task is to map residential areas and buildings, there is no need to map the yard.

If you need any help, feel free to leave a comment here and post a screenshot of the area that you are mapping.

“Das machen wir wieder!” – Das war das Elbe-Labe-Meeting 2016

2016-12-13T14:32:33+00:00

Die Teilnehmer des Elbe-Labe-Meetings 2016. Bild unter CC BY-SA 4.0, User BigDaddy73.

Es ist früh an einem Samstagmorgen im Oktober in Dresden, als für viele OpenStreetMap-Enthusiasten der Tag beginnt: Das Elbe-Labe-Meeting findet zum ersten Mal überhaupt statt. Das Ziel des Treffens: Mapper und auch Entwickler aus dem tschechischen und deutschsprachigen Raum zusammenzubringen, um sich gegenseitig kennenzulernen und um sich über OpenStreetMap auszutauschen. Oft begegnen den verschiedenen Communities die gleichen Herausforderungen – warum sich also nicht einmal austauschen?

Wanderwege – auf Tschechisch und Deutsch

Die Teilnehmer bewundern das Design des offiziellen Elbe-Labe-Meeting T-Shirts, das den Verlauf der Elbe (tschechisch: Labe) zeigt. Bild unter CC BY-SA 4.0, User BigDaddy73.

Die Teilnehmer sind neugierig aufeinander, und sie kommen aus verschiedenen Regionen Tschechiens und Deutschlands. Schon am Abend zuvor gab es regen Zulauf bei einem gemeinsamen Abendessen mit anregenden Diskussionen. Am Samstag gibt es erstmal T-Shirts, die Alex (User Blackdeeranger) selbst designt hat. Der Fokus des Morgens liegt auf Wanderwegen, Mountainbikerouten sowie Routing auf OpenStreetMap-Daten. Sarah Hoffmann, die Macherin hinter waymarkedtrails.org, erklärt die Feinheiten des Taggings von Wanderwegen. Insbesondere Routenklassifikation und das Tagging von Wanderwegsymbolen birgt so manche Stolperfalle. Direkt im Anschluss beleuchtet Miroslav Suchý in seinem Vortrag den aktuellen Stand des tschechischen Wanderwegenetzes: Über 40.000 Kilometer wollen kartographiert werden! Bei der sich anschließenden Diskussion zeigen sich viele Gemeinsamkeiten: Der Unwille von Organisationen, Geodaten zur Nutzung für OpenStreetMap freizugeben, ist ein länderübergreifendes Phänomen – genauso wie das Engagement der Mapper, einfach parallel zu proprietären Datensammlungen eine freie Karte der Welt zu schaffen.

LIDAR und 3D Datenakquisition – nur eines der vielen Themen der einzelnen Workshop-Gruppen. Bild unter CC BY-SA 4.0, User BigDaddy73.

Wer Wege erst mal erfasst hat, der möchte sich auch darauf bewegen. So dreht sich der Nachmittag um die neuesten Entwicklungen im Projekt OSRM (Open Source Routing Machine), das für die Berechnung von Routen auf OSM-Datenbasis genutzt wird. Daniel Hofmann, der bei Mapbox angestellt ist und in Berlin an OSRM entwickelt, erklärt Routingkniffe und das komplexe Zusammenspiel zwischen Routenberechnung und hinterlegter Tagginginformation. Dabei wird auch das Routing auf mehrspurigen Kreisverkehren und Einbahnstraßen, deren Richtung sich nach Tageszeit ändert, besprochen. Tatsächlich wird in der anschließenden Diskussion und einem spontanen Workshop deutlich, dass das Tagging von Einbahnstraßen mit wechselnden Fahrtrichtungen verbesserungswürdig ist – und die Community findet noch am selben Tag einen Fix für dieses Taggingproblem (Reversible Oneways vs. Alternating Oneways).

Tiefe Lernverfahren und das automatische Schätzen von Dachgeometrien aus Satellitenbildern

In Lightning Talks und Workshops werden in kleineren Interessengruppen verschiedene Themen intensiver diskutiert. Neben der Oneway-Tagging Gruppe bildet sich eine tschechisch-deutsche Gruppe zum Thema “Tagging für Quad Kraftfahrzeuge”, eine Gruppe zu “LIDAR und 3D Datenakquise für OSM” sowie “Visualisierungsstrategien für Wanderwege”. In den Lightning Talks stellt Jan Marsch seinen neuen “OSM Buildings Editor” vor; Martin Tesař demonstriert dynamische Legenden in der tschechischen Wanderwege und Mountainbikekarte; Daniel Hofmann erläutert die automatische Schätzung von Dachgeometrie-Informationen aus Satellitenbildern durch tiefe maschinelle Lernverfahren. Daneben werden noch Maponshirt.com sowie neue Funktionen von taginfo vorgestellt.

Wikivoyage und Karten für Reiseführer – Diskussionen auf dem Elbe-Labe-Meeting 2016 in Dresden. Bild unter CC BY-SA 4.0, User BigDaddy73.

Nach einer langen Nacht mit gemeinsamen Abendessen beginnt der Sonntag mit einem Vortrag von Roland Unger. Roland arbeitet seit Jahren ehrenamtlich bei Wikivoyage, einem Wiki, das freie Reiseinformationen für Jedermann zur Verfügung stellt. Besonders im Fokus stehen die Karten, die für heutige Reiseführer unerlässlich sind. Hier entspinnt sich ein reger Austausch, denn die Mapper haben viele Vorschläge an das Wikivoyage-Projekt.

Am Nachmittag bilden sich wieder freie Diskussions- und Interessensgruppen. Neben einer “Vektortiles und Toolchain” Gruppe finden sich auch Teilnehmer, um über die JOSM-Plugin-Entwicklung sowie über das Kartographer Plugin für Mediawiki zu diskutieren. Angeregt wird über “Alternating vs. Reversible Oneway” und “Visualisierung von Wanderwegen” diskutiert. Das Meeting klingt am späten Nachmittag bei Kaffee und Kuchen aus. Die Teilnehmer verabschieden sich voneinander, und am Ende steht fest: “Das machen wir wieder!”

Besonderer Dank gilt dem FOSSGIS e.V., der durch seine Förderung das Treffen, insbesondere die Räumlichkeiten und die Verpflegung, erst möglich gemacht hat. Daneben hat Alex die T-Shirt-Produktion privat teil-subventioniert. Herzlichen Dank dafür! Außerdem gilt Dank dem Organisationsteam, bestehend aus Jochen, Alex, Matthias, Tim und Stephan sowie allen anderen, die bei der Organisation des Treffens behilflich waren.

3 years of welcome messages, more than 3400 of them

2016-12-13T10:03:46+00:00

Three years back I started sending welcome messages to new mappers on behalf of SOSM, using a simple tool chain based on the RSS feed of new mappers from Pascal Neis.

The message is not customised as from the beginning it was seen as a replacement for the welcome message that had gone away with the web site redesign. The text (in 4 languages, no Romansh version though) is designed to welcome the new contributor and give pointers to the resources available nationally.

Has it worked? Difficult to say, as the whole point was a replacement of something that existed before, we didn't expect drastic change and we didn't get it.

And, no, I'm not stopping :-)

New data sources available for Western Australian roads

2016-12-13T01:27:55+00:00

The Main Roads department of Western Australian recently released quite a few datasets under the Creative Commons Attribution licence. We have explicit permission to use two of these in OSM: the Road Network (MRWA-514) and Road Hierarchy (MRWA-515).

I'm part of a local geogeeks group that meets fortnightly in Perth, and with the help of some people far more knowledgeable than me about spatial stuff I've been attempting to derive a comparison between the Main Roads data and what's already in OSM. That's a work in progress (eventually it'll spit out an OSM file containing only correctly-attributed roads that are missing from OSM), but for the time being I'm going down a much more manual route:

1. Download shapefile from the data.wa.gov.au site linked above

2. Use ogr2osm to convert it to OSM format:

python ogr2osm.py RoadNetworkMRWA_514/RoadNetworkMRWA_514_1.shp -o mrwa514.osm`

3. Create a JOSM style file that makes the names stand out:

way[cwy=Single] {
text: auto;
width: 3;
color: #c0c0c0;
text: "road_name";
text-position: line;
text-offset: 14;
font-size: 16;
font-color: lightyellow;
}

4. Mostly, road geometry is actually already in OSM, but the names and road types aren't. To make it easier to find where to work, I apply filters in JOSM to hide everything apart from roads with no names. Then it's just a matter of clicking a road, adding its info, and as soon as it's got a name it disappears (thanks to the filter).

This is still pretty slow, but it's safe. I'm sure there's going to be lots of better ways to work with this, but at least some missing names (and geometries) are being fixed.

I'll use source:name=Main Roads Western Australia to designate where the name has come from. The geometries I'm double-checking against Bing.

First #geomob of 2017 - 25th Jan at new venue

2016-12-12T23:45:11+00:00

Friends,

it’s hard to believe, but we’re almost to the end of 2016. Many thanks to all of you for another great #geomob year.

Turning our attention to 2017 our first event will take place at 18:30 on Wednesday the 25th of January. I’m pleased to announce we’ll be at a new venue. Traveltech Lab has generously agreed to host us! They’re at 6th Floor,
2 More London Riverside, London SE1 2RR. I am told the view over the river and towards Tower Bridge is amazing. The nearest tube is London Bridge. Please sign up on the Lanyrd page (if possible, sadly it seems the service has become unreliable) so we have a sense of the numbers.

Many thanks to them for volunteering their space. As a travel incubator we’ll hopefully be hearing from their start-ups at #geomobs in the future.

Despite the new venue, we will follow the same tried and true format from the past. Five speaker shave volunteers to share their projects with us. After a very brief introduction each speaker will have 10-15 minutes to discuss their project, then take a few questions. At the end of the evening we’ll vote for the SplashMaps best speaker and then retire to a nearby pub for discussion.

Our speakers for the evening are:

Ed Leon Klinger, co-founder of Flock
Mike Thompson, creator of AdmissionsDay
Alice Gadney from Silver7Mapping
Sam Hill, co-founder of Run an Empire
Sean McGee will show off his “What are you looking at” App

I hope you agree it looks like a great line-up.

Allow me to close by once again thanking the various groups that make #geomob possible:

Our sponsors: OpenCage, KnowWhere Consulting, What3Words, and SplashMaps who fund the post-talk beers. Please let us know if you’d like to sponsor.
The venues that have generously hosted us: UCL, Geovation Hub, and the BCS.
Everyone who volunteered to speak over the last year
And last, but not least, you, our dear attendees.

For those of you anxious to plan the year ahead, please put Wednesday the 29th of March in the calendar, when #geomob will be back at Geovation Hub. We have a few excellent speakers already confirmed, but are also on the hunt for another volunteer or two.

Happy holidays to one and all and see you on the 25th at Traveltech Lab

- One final note for those still in need of a geo gift, check out our sponsor SplashMaps’ offers.

Routenplanung — richtungsändernde Einbahnstrassen

2016-12-12T16:42:17+00:00

Ab und an berichten uns OSRM Nutzer von Umwegen die wir auf Anhieb nicht erklären können. Das folgende Beispiel zeigt eine solche Situation: der Flottsundsbron, eine schmale Brücke mit abwechselndem Verkehr in eine Richtung, im Süden von Schweden. Um solche und ähnliche Situationen handhaben zu können wurde vor Kurzem der oneway=alternating Tag in OpenStreetMap eingeführt.

Flottsundsbron Foto von Mapillary Nutzer alatius lizenziert CC BY-SA 4.0.

Bisher hatte der Flottsundsbron einen oneway=reversible Tag, was dazu führte, dass wir diesen Weg als nicht befahrbar markiert haben. Warum der Tag so problematisch für die Routenplanung ist, zeigen die folgenden zwei grundlegenden Unterschiede in seiner Benutzung:

Zum Einen wird der Tag verwendet um schmale Brücken und Tunnel zu markieren, die ihre Fahrtrichtung relativ häufig ändern (minütig, oft gesteuert durch Ampeln). Bei der Routenplanung können wir also die Wartezeit mit einkalkulieren und den Nutzer trotzdem darüber leiten. Flottsundsbron ist ein Beispiel für eine solche richtungsändernde Einbahnstrasse.

Zum Anderen gibt es Einbahnstrassen die ihre Fahrtrichtung relativ selten ändern, wie zum Beispiel Autobahnen um Pendler früh in die Stadt zu bringen und Abends wieder aus der Stadt heraus. Für diese Situationen macht es keinen Sinn bei der Routenplanung den Nutzer warten zu lassen, ohne die genaue Zeit zu kennen. Die Autobahn I-95 in Virginia ist ein perfektes Beispiel dafür.

Beide dieser grundlegend unterschiedlichen Semantiken wurden bisher im oneway=reversible Tag kombiniert. Das macht es bei der Routenplanung unmöglich zwischen den beiden Fällen zu differenzieren.

Deswegen wurde nach langer Diskussion auf dem Elbe-Labe-Meeting in Dresden der oneway=alternating Tag eingeführt.

Damit wird eine Unterscheidung möglich:

Hoch-frequente Änderungen der Fahrtrichtung die der Nutzer abwarten kann werden nun mit oneway=alternating getaggt.
Niedrig-frequente Änderungen der Fahrtrichtung können weiterhin oneway=reversible getaggt bleiben.

Mit dieser Unterscheidung kann die Routenplanung den oneway=alternating Weg in Betracht nehmen und gleichzeitig die Wartezeit mit einkalkulieren.

Hier sind die Wiki Seiten der Tags:

Der nächste Schritt wäre es für oneway=reversible die genauen Zeiten zu taggen und für oneway=alternating die Frequenz bzw. die Wartezeit.

Für mehr Details gibt es hier den ursprünglichen Nutzerbericht. Richtungsändernde Einbahnstrassen sind im OSRM v5.5 Release enthalten. Für Feedback zur Routenplannung sind wir im OSRM Repository, im IRC oder auf der osrm-talk Mailingliste anzutreffen.

Routing — alternating oneways

2016-12-12T16:27:34+00:00

Every now and then OSRM users report routes that take puzzling, unrealistic detours. For example, a user reported this route that went to extensive means to avoid going over Flottsundsbron, a narrow bridge with alternating direction of traffic in the south of Sweden. Investigating this strange route led us to the oneway=alternating tag in OpenStreetMap.

Flottsundsbron Photo by Mapillary user alatius under CC BY-SA 4.0.

The oneway=reversible tag's usage on Flottsundsbron meant our routing engine avoided it completely. A search for this tag in OSM will reveal that it has been used to express two different semantics.

On one hand the tag has been used to describe narrow bridges and tunnels that alternate direction of travel on a high frequency, say every five minutes. Encountering a oneway of this variety may add some amount of waiting time to the user's route, but the route is always accessible. Flottsundsbron is an example of this type of way; a changing traffic light dictates the direction of travel.

On the other hand there are oneways that change direction of travel very infrequently, like highways for the commute into a city in the morning and out of it in the evening. For these it does not make sense to let the user wait until the direction of travel changes. This highway, I-95 in northern Virginia is an example of a highway that reverses its direction twice a day.

If the routing engine doesn't know about the frequency of direction change there is no way to distinguish between the two semantics being overloaded in the oneway=reversible tag.

To pacify this ambiguity, we came up with the oneway=alternating tag at the Elbe-Labe-Meeting. The semantic distinction is clear now:

high-frequency direction changes can be tagged as oneway=alternating
low-frequency direction changes continue to be tagged oneway=reversible

With distinct semantics in place we route you over oneway=alternating but apply a penalty for waiting time.

Check out the tags' Wiki pages for more detailed descriptions:

The next step would be tagging oneway=reversible with the specific times and oneway=alternating with the waiting times or the frequency.

You can read up on the original discussion with the Routing Engine. This feature is included in the latest OSRM v5.5 Release. We're always glad for user feedback; in case you stumble over issues like this please talk to us! You can find us in the OSRM Repository on IRC and on the osrm-talk mailinglist.

Leaflet plugin

2016-12-12T14:05:00+00:00

I have been trying to replace a long-standing map based on the OpenLayers 2 library to LeafletJS. The main sticking point was that OpenLayers has a useful permalink function that changes the URL to include a query string that identifies the map location and which layers should be shown.

Leaflet has a neat plugin to show the location as a hash but that doesn't include the layers to show. After a bit of investigation I decided to try to write a Leaflet plugin to make all this easier.

If a map has optional base layers and some overlays it often will use the Layers control to make the choices easy to select. The layers are not easily accessible from the map object as only the currently displayed layers, not the hidden ones, are available. The Layers control has access to all the layers, but that control is not accessible from the central map object. The only way to have access to all of the layers is from the Layers control, so a new control, inherited from the Layers control seemed to be the right answer. HashLayers control was developed.

HashLayers does all that the Layers control does, of course, but adds the functionality of the URL hash. The hash looks like this:

#zoom/longitude/latitude/layers

This gets appended to the URL of the page that the map is on. Using the hash means the position and layers can be changed dynamically as the map is zoomed or scrolled around and as different layers are selected. Changing the hash value of a URL doesn't force a reload of the page and doesn't show up in browser history.

The zoom is the current zoom level and longitude and latitude are the centre of the map. The layers is a string representing the base layers and any overlays. If a base layer is selected 'B' is shown, 'O' shows an available base layer not selected. The overlays are shown as a string of 'T' or 'F' (true or false) showing if they are shown or not. A typical hash might be:

#12/-0.393105/53.775095/BOFFTF

This has the first base layer visible, the second one not showing and four overlays available, but with only the third one visible. These selections will be reflected in the visible selection control too.

If a map is created with the HashLayers control on it and a hash is passed in the URL, the map will centre on the location and zoom specified and show the requested layers. If no hash is passed then the default location and zoom will be used from the setView() or map options as normal. Layers will be shown as they were added to the map. A hash to reflect all this will be appended to the URL which gets updated with every change. There is no need for the OpenLayers permalink control.

I now need to test it more carefully and decide if it is worth publishing as a Leaflet plugin.

Реки Сахалина

Год назад сгорел комп и появилось время на чтение документации и форума Gis-Lab.
Давно собирался разобраться, что за зверь - GRASS GIS и как его хотя бы запустить...

В течении года пробовал разные подходы, настройки, аддоны и версии GRASS GIS - короче, развлекался по полной.
Так как уже почти 2 года сижу на Ubuntu, каждый шаг превращался в мини-квест... в целом забавно, но местами выбешивает.

В качестве цели ставил себе задачу - пройтись по Сахалину и геокодировать реки, без детальной прорисовки.

Кстати, можно обойтись и без GRASS GIS для этой задачи.
По наводке gamm с форума Gis-Lab, можно воспользоваться Whitebox GAT
http://www.uoguelph.ca/~hydrogeo/Whitebox/download.shtml

алгоритм расписан на gis.stackexchange.com

SRTM:

Полученный в итоге GPX использовал в качестве направляющих и подсказок, а порой и в качестве ограничителей детализации... как по минимуму, так и по максимуму. Что особенно заметно на верхней половине острова.

Конечно, пробовал результат обработки SRTM и в SHP выгружать, а его открывать в JOSM с помощью плагина opendata. Там сразу встает ряд проблем, которые хотя и можно решить, но в итоге тратишь столько сил и времени, что обрисовать в ручную и проще, и гораздо быстрее.

Хотя... есть пара трюков, если сильно озадачится.

Потратив некоторое время на изучение wiki и написав несколько скриптов под разные задачи, подбор параметров стал проще и быстрее.

Во время различных экспериментов, обратил внимание, что подобрав параметры площади водосборного бассейна, можно получить что-то похожее на пирог региона для http://mapcraft.nanodesu.ru/.

Что отлично подходит для мапинг-пати по отрисовке гидрографии или дорог во всем регионе.

J'ai trouvé le chaînon manquant !

2016-12-12T09:07:30+00:00

Comme vous le savez peut-être, je penche depuis un bout de temps sur une amélioration du schéma actuel de cartographie des transports en commun. Outre diverses clés et valeurs pour préciser le niveau de service des lignes, et les informations disponibles aux arrêts, e principal point de ma proposition consiste en une division de ce qui est aujourd'hui représenté par public_transport=platform. Aujourd'hui, ce tag peut designer un quai, un poteau d'arrêt ou un abri. Ma proposition utilise des tags différents pour chacun e ces cas. Or en pratique, le poteau est toujours sur le quai non ? Pourquoi les séparer alors ? Hé bien parce que le poteau peut ne pas être sur le quai ! Samedi dernier, lors d'une visite à Milan, j'ai rencontré un arrêt de ce genre. Le tramway circulant au centre de la chaussée, le quai est en îlot au milieu de la chaussée. Mais par contre, le poteau a été planté au bord de la chaussée, sur le trottoir. Il y a donc une voie de circulation entre le poteau et l'arrêt.

そのメーカーのキャットフードが好き

2016-12-12T08:42:36+00:00

キャットフードを購入して、バーコードを集めて応募をすると、しっかりプレゼントを発送していただける援助があります。
平年行われているので、購入をする度にバーコードを切り取っている。
猫のことを知り尽くしてあるペット食材の社なので、どういうものが猫の好きに合うのか思い切り分かっていてくれている。
猫が快適に過ごすことが出来るペットベッドであったり、爪とぎが今年のプレゼントなので、魅力的です。
中には応募を通じても全事前ではないメーカーもあるので、全事前はほんとに嬉しいですし、プレゼントも多々選べるはウリが大きいと思います。
根っからそのメーカーのキャットフードが好きなので、購入をすることに心配はありません。
全事前を行っているからわざわざ購入をするのではないのです。
好きなキャットフードだからこそ、購入を通じていて、全事前はオプションのようなものです。
でもただ購入をするよりは全事前という形でフィードバックされたほうが嬉しいですし、バーコードを揃えるエンターテイメントもあると思います。
コーデをすることはなかなか大変ですが、少しずつ配列が貯まって出向くというのも嬉しいですし、手広く集まるというとても嬉しくもなります。詳しくはこちらから

Back in July, we talked about the Los Angeles building import hitting > 1 million mark for LA City and last month, we already imported 2 million buildings covering the rest of the county. We are not finished yet ;)

Read on for what we are doing in the last couple of months.

MaptimeLA in Catalina Island

The local community through @MaptimeLA has also been busy validating the data on the ground. A few of them took a ferry to Catalina Island for an awesome mapping weekend! Aside from validating the imported buildings, they added local features and Mapillary street/trail level photos across the island.

Updated imported data for 2008-2014

Also last month, LA County GIS released an update to the building data covering changes from 2008-2014. The team decided to pause importing buildings to check the new dataset. The data is now ready and mappers can continue the import starting with Malibu & Santa Monica Mountains.

New buildings (2008-2014) are now available for import

What about the previously imported buildings?

We are reviewing the best strategy to update areas with already imported buildings. Conflation is challenging and we need to make sure that data already improved by mappers won't be damaged unnecessarily. If you have thoughts on this, hit us on gitter or the project's repo.

Retaining New Users

2016-12-12T06:46:09+00:00

This is a blog post on my efforts to connect with new users. OpenStreetMap adds new users at a surprising rapid rate. If only they would stick around. So what can we do to increase their longevity? Not have extra money, bribes are out. So is swag, not that I have any of that either.

Right now I'm giving new users thumbnail information on OSM and inviting them to join an OSM Meetup group. After the new year when I'll pull together some statistics to see if information alone is useful or if I should try another approach.

What else can I try?

Last Friday 9 December I thought that I'd spotted yet more Khazis on houses near the head of Perlethorpe Drive but in fact it was more interesting than that. These 1959 houses had been built with combo Wash-houses and Coal-Sheds.

These two are in superb condition:

Building a Women's work group in Openstreetmap Latin America, or How to Make Community

2016-12-11T02:25:34+00:00

The gender gap in technologies and information's world is a commonplace, so assumed that few solutions are sought. This reflection appeared through an internal debate in the regional chat of OpenStreetMap Latam, allowing that the concerns of several people could concretize in a work line within the community. This text could also be a reflection on how to build community.

Why and how did the need to build a forum on the gender gap in OpenStreetMap appear

The OpenStreetMap community has various channels for relating, communicating information, giving directions, debating opinions: mailing lists, wikis and chats, country or region based, working group based. In the ConDatos 2014 event in Mexico City, where several people from the continent meet each other, linking the Openstreetmap community of Latin America in a more integrated way was proposed, firstly creating a mailing list and a regional chat.

I wasn't personally involved in these media until summer 2016 when I was invited to the chat. A chat of about 100 people can be a space where topics are drowned, but also a space where new perspectives, information and conversations emerge. In relation to the State of the Map Latam event in Sao Paolo, November 2016, where an extremely low participation of women was taking place, the issue of the gender gap in the community appeared as a problem to be addressed. The chat then had an active participation of no more than 5 women over then 80 registered. We began to talk about propositional actions to achieve greater participation in the SOTM. The ongoing debate was first about the need to have data about female participation in the mapping, but this data not exist since the profiles of OSM users are anonymous. We talked about some analyses presented previously in another SOTM event (Brussels 2016), which sought to interpret the mappers gender through the types of mapped objects. The analysis related a type of commerce and service with a specific gender: services considered male-oriented (car shops) appeared more frequently on the map than services considered typically women-oriented (hairdressers and services oriented to personal aesthetics). This analysis was considered inconsistent for the most of us, generated passion in the chat and raised to ask: 1. How to obtain evidence of the relative participation of different genders 2. What difference can there be in the perspective, the needs and the interests on the space, between the different genders 3. Why it is so important to integrate this axis into our community actions and information management

What actions were proposed?

Certain countries, such as Argentina, had already a map of the location of their users, being a local community support. We all decided in the regional chat to replicate the map at the LatAm level asking each one to locate him/herself on the map, with gender information. Although it grows permanently, the map reflects the gap in the same proportion as estimated. It is proposed to frequently invite new OSM members to mark his or her location on the map. In addition to giving a visualization of the gender gap, the map is a nice product and a medium for identity group construction. Because it allows to clearly perceive the problem of the very low female participation, it gave the impulse to the formation of the internal group: #OSMchicas.

The discussions focused secondly in the need to develop an effort to summon more women to the SOTM event: from the local community of Brazil, from the region, and orienting the scholarships that are generally oriented to have a wide participation, towards women. In this way, the participation of women from the chat was greater, they could attend the event and meet personally. As a consequence, this group of women strengthened and had the possibility to propose specific actions to address this issue, in advance.

The plan for the event was: 1. Participate individually with their individual work presentation, contributing to a better gender balance in the program 2. Organize a women's panel where the topic would be discussed from various perspectives: Why greater participation of women in the OSM mapping is important to build the map with information that represents society as a whole (it appears as a crucial point since the map is the basis for territorial planning and public policy); Telling about our projects related to gender, women, space, and mapping; What is our experience as women in the community and in the data and technology world; How we could remedy the gender gap in the community, and unit everybody into this debate and brainstorm. 3. Begin to build a network of women among those present, involving less active or new women in this area.

In addition, a pre-SOTM toast was proposed to get to know and strengthen ideas before the panel, being a pretext to summon more people not very connected with the community or the subject.

What results did we have?

We can consider that, as a first step of linking, these actions with a gender perspective and female empowerment have had a triple success: raise awareness on this issue in the community; start a network of Latin American women broader than the starting nucleus; Through gender-based engagement, integrate isolated people into the OpenStreetMap community. The panel also gave rise to several agreements, in addition to identifying us and forming a new workgroup, with a parallel chat of 15 people.

We invite attendees and participants as well as social networks to brainstorm about the gender gap with the hashtag #OSMintegra. This action will be a permanent task of the OSMchicas group.

We also understood the need to link and make more visible the different works with a gender perspective that we are doing throughout the community, linked to the construction or use of the map, or technologies associated to OpenStreetMap, as well as training actions for women in any kind of context. It is about documenting and having a tendency to publish in all possible ways (and firstly in this OSM diary) to give space to the subject.

Reducing the gap also implies a constant effort to increase women's participation in OSM, data and freeware events in general. Added to a representation gap, there is a clear problem of funding for traveling, and targeted call, which can be achieved through the work of network construction. A central task of OSMchicas will be the search for sponsorship of all kinds to finance: * Travel scholarships for women from the community or women who can contribute to the community, to attend the most important events * Support for the logistics of activities that target women participation

As a result of the link that naturally happens in a regional scale community event such as SOTM Latam, we have been interested in participate in an important upcoming event for a wider community: CubaConf 2017. Several dimensions today lead us to have a more committed attention to this event: the interest in the challenge of a free technology event in the context of Cuba, and a challenge for OSMchicas to promote in a first occasion the participation of women.

Our participation in the organization of CubaConf, with ideas and proposals, gives us a pretext to continue building our instruments of work and OSM women's network. It also lead us, given the particular context of Cuba, to develop new strategies, projects, methodologies for local community participation.

Many things to come

It seems to have a high relevance to continue analyzing participatory processes in a network like Openstreetmap, but not only. Explore the mechanisms that result in the building, growth and strengthening of a community; Identify how leaderships are built and how these leaderships can be as positive as inhibitors for certain parts of the community, based on a gender or any other difference. This analysis is nourished by our expression and debates, both in our differences and internally to a subgroup. In this sense, separating women in a reserved space is not a matter. They are given the opportunity to work in several groups and expand their opportunities to express, propose, take leadership. It was quite revealing how the construction of a separate chat for this new group led us to have new ideas and how it encouraged the participation of people who were already part of the regional community, but less visible.

Our participation in CubaConf can have a positive impact in boosting the participation of women in Cuba and in the region, by continuing to build networks, and to give greater scope to training. We will be seeking funding and having a participation of more institutions to achieve this.

We invite to join a general effort of documentation to the people who can contribute to this issue of cartography and the uses and perceptions of space by women, being a necessary link to have an integrative vision of the territory. People from the Openstreetmap community are invited to write on this topic in their OSM User Journal, with the hashtag #OSMintegra (in diaries and in social networks), that allows to link the contributions, to spread them more easily, and to continue to invite to be part of the debate. Finally, any link will be enriching to understand better this topic. The group of girls of OSM Latam was very enthusiastic following the meeting in SOTM Latam of Sao Paulo. Thanks to the organizers!

OSM data in MapMyIndia

2016-12-10T09:04:30+00:00

In India, MapMyIndia is one of the biggest aggregators of commercial map data, including running their own fleet of mapping cars, so it was quite interesting to find OSM data in their map for areas i'm familiar with and have mapped on the ground.

Its not all OSM though, will need to dig more into how they mix the data.

Mesclando fotos com trilhas GPX para uso em Mapillary ou OpenStreetCam

2016-12-10T00:14:23+00:00

Introdução

Para registrar fotos e mesclá-las com trilhas GPX, o primeiro passo é garantir que o relógio da câmera e do celular estejam sincronizados. Para câmeras como a GoPro, é necessário realizar essa configuração manualmente; já a Giroptic 360cam acerta o relógio automaticamente, ao sincronizar com um aplicativo de celular.

As trilhas GPX podem ser gravadas com diversos aplicativos; sugiro a utilização do OSMTracker para Android.

Instalação

Você precisará instalar as ferramentas exiftool.

As instruções de instalação a seguir foram feitas em um computador rodando Mac OS X.

Você pode instalar o exiftool usando o brew, um instalador de programas em linha de comando. Caso nunca tenha utilizado esta ferramenta, acesse o site brew.sh e siga as instruções de instalação.

Com o brew instalado, abra seu terminal e entre o comando brew install exiftool

Além disso, você precisará do script interpolate_direction.py do pacote mapillary_tools. Baixe ele através deste link e descompacte-o em um local em seu computador.

Utilização

Primeiro copie as fotos para uma pasta em seu computador. O ideal é que as fotos fiquem dentro de uma subpasta. Por exemplo:

Agora abra um terminal e entre na pasta em questão.

Primeiro, vamos executar o exiftool para escrever a posição de cada imagem, baseada na trilha GPX. Para isso, execute:

exiftool -geotag nome-do-arquivo-gpx pasta-das-fotos

Dependendo da quantidade de fotos, esse procedimento pode levar alguns minutos. Aguarde o comando terminal de executar.

Por padrão, o exiftool cria cópias de segurança dos arquivos. Caso nenhum erro apareça no terminal, podemos apagar essas cópias sem problemas. Para isto, execute:

rm pasta-das-fotos/*.JPG_original

Com isso todas as fotos tem uma latitude e longitude. Falta ainda o parâmetro bearing, que é a direção para qual a câmera estava apontada. É possível extrair essa informação, através da posição da próxima foto e da foto anterior. Para isso executamos:

python pasta-mapillary-tools/python/interpolate_direction.py pasta-das-fotos

Tudo pronto! Agora é só subir as fotos para o servidor. :)

Street Art in Wollaton Avenue

2016-12-09T21:37:48+00:00

A volley of Winter Virus breached my defences — the first in 10/15 years — so I've spent a week or so indoors with Bronchitis.

At one stage I examined my phlegm in a piece of tissue & it was the colour & consistency of a mid-green emulsion paint typical from the 1980s. My more recent sputum is clear, with the odd bit of yellow stuff in it, and the earlier result may well have been a delusion caused by sleep deprivation (every time I fall asleep I cough & immediately wake up again). Well, whatever, I finally got to the point that I could convince myself that I was both strong enough to go out, that I was no longer a male variant on Typhoid Mary, plus I needed the fresh air. The boundary streets of Phoenix Farm Estate in Gedling, Nottinghamshire were waiting to be surveyed.

I actually reached a street sign on Arnold Lane, Gedling as I walked towards Gedling Church that said “Gedling Village”, which suggests that there should be some GIS for the village. The section that I've been doing so far is called “St James” (electoral ward), whilst the next bit on the east side of the (closed-down last September) Sherwood Academy is called Phoenix Farm Estate (also an electoral ward, although far more interesting as a physical link between JRR Tolkien & the initiation of Lord of the Rings).

Sherwood Academy is rapidly rotting on Wollaton Avenue, and it was on that same road that I first spotted today's very fine example of Street Art / Garden Furniture. It is a miniature water fountain, and the Householder offered to switch it on, so we all have two bites of the cherry for this one:–

も、今回の地方自治体書士トライはある意味任務として受験するということもあってそれだけに今回の受験は力が入っていらっしゃる。（落ちた事例が照れくさいのですが。）
これで及第したら著述の任務の選択肢ものさばるし、お金貯めてビジネス拡大して呼物生み出すということもできるようになりますからエッセイストだけではなく地方自治体書士としても仕事ができるようになります。
当然及第して地方自治体書士としての登録することがポイントだ。
やはり著述の任務を始める前に機関に提出した実録も変更しなければいけなくなってしまうし、上呼物を出さなければいけないから呼物のアレンジも必要です。
それで地方自治体書士として設立するには相当設立やるだけのお金をためておく必要があります。
設立下部も地方自治体書士会に会費を納めることもしなければいけないし今のうちに資金をためておきたいです。
その前に受験勉強をする必要がありますけど、受験終わったら本格的に任務を複数こなして稼ぐことを考えています。エンジェルプレミアマジックソープは楽天で買うな

手動によるグッズ部類がディスプレー

2016-12-09T06:50:15+00:00

日和が良かったので、久しぶりに渋谷東口のヒカリエにグッズを見に行きました。
渋谷駅前は東急線の再発達中で、周りは覆異がされてる中に大型のクレーンや工事貨物などがあり工事まん中でした。大型のビルが２棟建設達するそうです。
最近ちょい暑くなってきたからか、店内のあちこちの塀には観葉植物が埋め込まれて涼しげなアピールがされていました。
店内の光線だけでは日照不完全になりそうですが、操縦はどうしてしてるのでしょうか。
店内では「いいねNIPPON」という特集を通じてあり、所々の職人の手動によるグッズ部類がディスプレーされていました。
袋、センス、刷毛など丁寧に作られた賜物は迫力がありました。
売り値は大きいので購入することは難しいですが、品質の良いものは長期使い込んでも壊れたりしないので一部分欲しいなと思いました。
グッズ暖簾ではガラス器に入ったモスという多肉植物のちっちゃなテラリウムという内側が素敵でした。
ペイントしたブリキ缶や吊り下げられたワイヤーに豆観葉をあしらったものが飾られていて園芸欲しいなと思いました。
が、代を見ると数千円で園芸暖簾と比べるとまさか割高で諦めました。
それでもグリーンを彩る相応しい参考にはなりました。マンションにおける缶をペイントして鉢保障を作ってみたいですね。興味のある方はどうぞ

Creating MapRoulette Challenges from GeoJSON

2016-12-08T21:35:28+00:00

This post also appears on the MapRoulette wiki

Creating MapRoulette challenges has never been easier. You can use the API or the brand new Challenge Wizard. I will cover the API in a future post. I have already covered the Wizard in general in a previous post, but right now I want to focus on creating a Challenge with a GeoJSON file.

In my example case, I have a GeoJSON file containing all the bus stop locations in Utah. I downloaded these as a Shapefile from the Utah GIS portal and converted them to GeoJSON using QGIS (there are other methods too, like ogr2ogr but I am too old for that). The result looks like this:

{
    "type": "FeatureCollection",
    "crs": {
        "type": "name",
        "properties": {
            "name": "urn:ogc:def:crs:OGC:1.3:CRS84"
        }
    },
    "features": [
        {
            "type": "Feature",
            "properties": {
                "StopId": 13840.0,

With this GeoJSON, I go to MapRoulette. After logging in, I go to my Project and create a new Challenge. (For more details on this, see my original post on creating challenges.) I enter the basic information for the Challenge:

Then I go to the next screen to choose my GeoJSON file:

I choose sensible numbers for the default zoom levels and base map:

And then I can complete my Challenge.

After a while I hit refresh in the browser and see that my Challenge is complete, with a little over 6000 tasks. This is the same as the Feature count in the original Shapefile, so I am happy. I can now go to a random task:

And see what the challenge looks like:

Looks pretty good! I can also click on the marker to see the GeoJSON properties:

Now everyone can help add bus stops near me!

But wait...

A word on the quality of this Challenge. It is really hard to verify that a bus stop actually exists using just Bing imagery. So this Challenge may not be suitable for anyone who does not already know the area very well. Another good source for people who don't know the local area is OpenStreetCam or Mapillary imagery. Without knowing if there is coverage for these sources, the Challenge can be hit or miss.

Finally, MapRoulette does not (yet) add the location of the new node to JOSM or iD when you click 'Edit', so you end up switching back and forth between MapRoulette and editor to figure out where to add the bus stop.

In the future, we want to extend MapRoulette to support better handling of GeoJSON source data:

Automatic adding of the feature to JOSM or iD (if possible) when clicking 'Edit'
parsing of GeoJSON properties and adding them as tags for the new feature

So with a properly formatted GeoJSON you could take most of the hard work out of mapper's hands and they would just need to verify and upload. That would be great progress for community-driven human imports. Please help make this happen, contribute to MapRoulette!

Happy Mapping!

Mapping

BushmanK versucht die Definitionen der englischen Tags man_made=mast und man_made=tower genauer zu fassen, was im Englisch-Amerikanischen Sprachbereich schwerfällt. Im deutschen Wiki sind schon seit längerem für einen Mast oder einen Tower klarere Definitionen vorhanden. Im Bereich tower_type gibt es ebenfalls Nachholbedarf.
Das Voting für nesting_site (Nistplatz) hat am 05. Dezember begonnen und endet am 19.
Markus Schnalke fragt, wie man damit umgeht, wenn für ein Proposal während des Votings noch gute Vorschläge eingehen.
Im Forum diskutiert man, wie man eine Fischzucht taggen kann.
[1] Marc Zoutendijk hat eine Overpass-Abfrage erstellt, um Fixme-Tags auf der Karte anzuzeigen. Andy verweist in den Kommentaren auf sein Tool zum Erstellen von GPX-Files zum Ablaufen solcher Fixmes (und Notes).

Community

Wir gratulieren Sarah Hoffman zur Ernennung als Mapperin des Monats.
Peter Bremer berichtet über einen neuen TMS-Server von Mapillary, der transparente PNGs für Karten-Overlays liefert, die visualisieren, wo sich Mapillary-Bilder befinden. Zudem erkärt er, wie man diesen Overlay in OsmAnd einbindet.
Mappa Mercia hat bei der Birmingham Highways Data Challenge einen Preis für ihre Verkehrs-Heatmap gewonnen. Glückwunsch!
Matt Amos fragt auf Github, ob OSM Mattermost, eine OpenSource-Alternative zu Slack, als Dienst für die OSM-Gemeinde zur Verfügung stellen sollte.
Markus wundert sich über einen gelöschten Benutzer und erfragt Details dazu.
Das russische Blog SHTOSM berichtet über Malenki und seine großartigen Dienste die er für OSM und unserer Community geleistet hat.

Importe

Anlässlich eines bereits laufenden Imports erklärt Christoph sehr ausführlich, warum ein Import von (sinnvollen) Daten noch lange nicht die Qualität unserer Datenbank verbessert, warum der Review von geplanten Importen so wichtig ist und weshalb es unangemessen ist, Personen persönlich anzugreifen, die ihre Zeit dafür opfern, sachliche Anmerkungen zu machen und damit nicht zuletzt die Qualität der Importe zu verbessern.

OpenStreetMap Foundation

Die OSMF bedankt sich nochmal herzlich bei allen Spendern. Ein besonderes Danke geht an Mapbox.
Durch einen Fehler bei der Erstellung der Liste wahlberechtigter Mitglieder muss die derzeit laufende Wahl zum OSMF-Vorstand unterbrochen und neu gestartet werden. Die Jahreshauptversammlung wird trotzdem stattfinden und dann bis zum Wahlende vertagt werden.
Christoph Hormann erklärt anlässlich der anstehenden OSMF-Vorstandswahlen, wie das verwendete STV-Wahlsystem genau funktioniert.
Auch bei OpenStreetMap US stehen demnächst Wahlen an. Im Wiki findet man die Manifeste der Kandidaten.

Veranstaltungen

Die FOSSGIS-Konferenz wartet auf eure Einreichungen für Vorträge und Workshops. Helft mit und unterstützt die deutsche Community, nur so kann es wieder eine großartige Konferenz wie in den vergangenen Jahren werden! Einreichungsschluss ist der 06. Januar.
Bis zum 16.12. werden noch Bewerbungen für die Austragung der ersten State of the Map Afrika angenommen. Bisher gibt es eine Bewerbung aus Uganda.
Michael Kugelmann weist darauf hin, dass es auch 2017 wieder einen Geospacial-Devroom auf der FOSDEM geben wird, für den noch Einreichungen gesucht werden.

Humanitarian OSM

Blake Girardot ruft dazu auf, sich an der Planung, Kommentierung und Entwicklung zum OSM Tasking Manager 3.0 zu beteiligen.
HOT bittet um Spenden bis Ende des Jahres. Der Erlös soll in 2017 für ein Förderprogramm verwendet werden, um 10 ausgesuchte Projekte, die besondere OSM Kapazitäten aufbauen wollen, mit dem notwendigen technischen Equipment auszustatten.
Severin Menard bemängelt die Transparenz von HOT und stellt die Spendenzwecke in Frage. In den Antworten versucht Tyler Radford aufzuklären und kündigt einen klärenden Blogartikel an.

Karten

Paul Norman kündigt größere Änderungen von OpenStreetMap-Carto an, die hoffentlich bald zu einem Datenbank-Neuimport führen werden. Ab dann könnten endlich neue Tags problemlos in die Hauptkarte übernommen werden.
OSMLanduse.org ist online gegangen. Die thematische Karte bildet Landnutzung/Bodenbedeckung nach OSM-Daten farbig ab und schlüsselt Anteile auf.

Open-Data

Beim Weltgipfel “Open Government” ist auch OSM unter anderem durch Emmanuel Bama vertreten.

Lizenzen

Im Forum wird diskutiert, ob man Videos (von Youtube) als Information zum Mappen heranziehen darf.

Programme

Chris Hill erklärt in seinem Blog, wie man OpenLayers einfach durch LeafLet ersetzt.
Ein Pull-Request der Brasilianischen OSM-Community, der die Portugisische Übersetzung korrigieren soll, wartet seit einem halben Jahr auf eine Reaktion durch Maps.Me. Die Übersetzungsfehler führen unter anderem zu falschen Eintragungen in die Datenbank.

Programmierung

Marc Tobias weist auf osm4scala hin, eine Bibliothek für Scala, die PBF-Dateien lesen kann.

OSM in der Presse

Die Washington Post zeigt sechs verschiedene Karten, implementiert ist auch OSM, welche die US-amerikanische Infrastruktur aufzeigen. Den neuen Präsidenten dürfte dies, mit der erforderlichen Investition von einer halben Billionen Dollar für die Erhaltung und Erweiterung dieser Infrastruktur, einige Nerven kosten.
