Resistance is Futile 1

More tales from the slopes of the Earl of Carnarvon's old stomping ground, formerly known as Marshall Hill and now known as Porchester Gardens.

What we are going to see here is the tale of a householder on Ethel Avenue that wanted to demolish his old cottage, which sits on a 0.16 hectare site, and replace it with 3 new 4-bedroom houses. In pursuit of that he has uprooted almost every green thing on the site (making it a wasteland), blocked access to a green way and received written objections from (almost) every neighbour. The application has been turned down, a judge has told him to restore the Public right-of-way & in response he is throwing a major-league strop, shrouding all his boundary with black plastic. Quite a tale. But first, some brief history of the area.

Marshall Hill was part of land enclosed by the Earl of Kingston (1672), sold in entirety by Kingston's heirs to Carnarvon (1912), and sold in lots to Nottingham citizens that wanted allotments for gardens (1887). Messrs Samuel Robinson, Charles Bennett and David Whittingham acted as guarantors for the latter action (the names of these three are known by householders throughout this 130 acre (52.6 hectares) neighbourhood). Only 2 years later roads began to be laid out & houses built on the plots; that really began to take off in the period following the Great War (1920s & 1930s).

Two things that, in my experience, feature a lot in Porchester Gardens are unadopted roads and Public rights of way; this little tale has both:

The unadopted roads are Emmanuel Avenue and Ethel Avenue. Both are single-track width private roads; Emmanuel Avenue in particular drops like a stone down the side of the hill from Porchester Road, and connects at right-angles to Ethel Avenue at it's bottom. Ethel Avenue looks like your classic private road (badly maintained with lots of potholes) whilst Emmanuel Avenue's tarmac is in superb condition. Here's the view from near the top (this and the photo in part 1 are essentially looking at each other from opposite sides of the valley between them):

Probably the best known local Public right of way is Donkey Steps (photo here). As the ecumenical Porchester Parish boundary runs up Donkey Steps it is likely that humans have been making use of that track for hundreds, and possibly even thousands, of years. It is this tread of history that is the backdrop to the importance of Public rights of way, and how easily they can be lost. To illustrate the latter we have an example close to both the main protagonist (on Kenrick Road) and to Donkey Steps:

Donkey Steps opens at the top onto Hillview Road close to where it meets Standhill Road (and I was told most forcefully “there is no space in ‘Hillview’!”). Opposite the Porchester Junior School, where Standhill makes a bend to the left, is the beginnings of a public footpath that runs first through to Florence Road, then to Daisy Road then Kenrick Road. It should continue next in a dead-straight line alongside 1 Kenrick Road (and the Ordnance Survey map still shows it travelling that way, then emerging onto Porchester Road between numbers 224 & 226, but today it is blocked at either end). A neighbour told me conspiratorially about the Kenrick Road householder that “the judge said that no-one had objected, so he got away with it”. I've been unable to find any report about that loss of rights, so cannot speak with any authority on the matter.

Now on to the heart of this Diary report, which is into the Green Way which runs from Kenrick Road to the junction of Emmanuel & Ethel Avenue. Or rather, used to run to those two avenues, since Mr Lee Freeley, the owner of 21 Ethel Avenue, has completely blocked off any exit from the green way. This is a recent view of the way from Kenrick Road (there are also views from Ethel Avenue in a 2015 Nottm Evening Post story and Google Streetview (October 2014)):

Mr Freeman proposed to use this green way as a driveway for one of his new houses. The whole story is perhaps a bit too long, so here are the highlights:—

1. There have been applications for redevelopment of 21 Ethel Avenue prior to that from Mr Lee Freeley (pdf) (24 October 2014). All have been declined by the local residents and the local authorities, including this latest.
2. A March 2011 Tree Preservation Order was made upon a Larch, a Yew & a Maple tree. The Maple tree had to be felled anyway. Bing map tiles show a capture date of 10/1/2011-3/26/2012 and a vast proliferation of mature trees on the site, all of which have now been cleared (the site is a wasteland). I also noticed Yew trees at 10 Ethel Avenue (the house opposite); Yew trees in medieval settings are often symptomatic of Religious activity on the site.
3. There is the curiosity of “a strip of land running along the backs of the properties fronting Kenrick Road. The ownership of this strip of land is unknown”. Cross-referencing this strip of land with the streetregister map suggests that it may have been yet another right-of-way running parallel to Kenrick Road as it seems to join with the other right-of-way running beside 1 Kenrick Road (although some other houses have added it to their own property, and the streetregister map wrongly shows it as part of 21's property).
4. The Green lane is owned by Gedling Borough Council. Local residents keep it in immaculate condition. A 163-signature petition was presented to the Council in April 2015 to make it into a public Bridleway, and an order issued the following week (see NEP story). Essentially this is the issue that has stopped the development. The PDF states:
   

Nottinghamshire County Council as Rights of Way Authority are currently dealing with a claim to make the Avenue from the junction of Ethel Avenue and Emmanuel Avenue to Kenrick Road a bridleway (Carlton Parish Public Bridleway) and have advised that the Avenue should be treated as a substantive right of way. I note the applicant has a personal right of way over the potential bridleway, as do the owners of the land on the Carnarvon Allotments and their successors in title. There is therefore a substantive number of people who potentially have the right to use the Avenue.

What a tortuous tale!

The CJK fonts seems to be missing in the standard layer, as the map in Asia looks strange.

I guess the Noto fonts that new openstreetmap-carto supported is missing in the server, so the Asian font uses the Unifont as the fallback.

Can somebody take a look and fix that?

On Oct 1st, anandisaac and I conducted an introductory session on OpenStreetMap as a part of a free software camp at Trichy. The participants were a mix of school students, college students from multiple disciplines and teachers.

For the participants, maps primarily meant paper maps used in Geography and History classes or Google Maps used for navigation.

We introduced OSM as an editable map to which everybody could contribute and how its data can be used by all. We showed them some projects based on OSM including the Chennai flood map and the Managua transport map by MapaNica. After showing such examples of how the map data has been used in interesting ways, the participants were given a small activity. They were split into teams and each team had to come up with an idea as to how they would use OSM data. Simply put, we asked them, "What kind of map would you build using OSM data?". The ideas they came up with were both fun and innovative! Listed below are some of them.

• A map of Trichy to indicate where policemen are likely to check for driver's license, speed limit, helmet, etc so that users can choose an alternate route avoiding cops.
• A map to highlight all the signals in the city so that emergency services like ambulance can use the map to plan the best/fastest route without signals.
• A map of forests indicating areas of animal movement. This could be used when humans need to go into a forest they may not be familiar with.
  
• A map of all the bus stops in Trichy with details of bus routes and timing.
• A map to find the nearest recharge (mobile talktime/data) shop.
• A map of all car & two wheeler service centres.

The activity kindled the curiosity of the participants to understand how they could use OSM. Some of the ideas brought out unique use cases. Though a few ideas may seem wild, the exercise drove home the point that they could use OSM in various ways. It encouraged them to think about map as a tool for their daily needs (beyond navigation) and how OSM powers them to be more than just a user of the map.

One of the teachers present in the audience was even curious to know if the map could be used to track students who do not attend classes regularly. Maybe she mistook OSM for the Marauder's Map.

The second and final day of State of the Map Asia 2016 is almost done and it has been great to hear and learn from OpenStreetMap colleagues from India, Japan, Indonesia, Taiwan, Sri Lanka, Nepal, Bangladesh, Russia, Sweden, the United States, the Philippines, and many other countries.

Ich hab ja in meinem ersten Post geschrieben, dass ich mich als Kartierer für ungwöhnliche Orte interessiere. Und neulich habe ich einen seltenen Ort entdeckt: Eine Fußballgolfanlage!

Fußballgolf ist lustig! Es ist änhlich zu Golf, doch statt mit Golfball und Schläger spielt man mit Fußball und Fuß. spielt man mit Fußball und Fuß. Wie bei Golf gibt es mehrere Bahnen, in jeder Bahn einen Startpunkt und ein Loch. Den Ball muss man mit so wenigen Tritten wie möglich ins Loch befördern. Der Spieler mit den wenigsten Tritten gewinnt.

Eine dieser Fußballgolfanlagen kann man in der Datenbank als Linie 107693223 bestaunen (habe ich eingetragen). Es wird zur Zeit auf der Standardebene nicht gerendert, aber das ist schon OK. Wichtig ist, dass die Daten stimmen.

Fußballgolf zeichnet sich auch dadurch aus, dass die Anlagen deutlich kleiner sind als bei Golf, aber größer als beim Minigolf. Die Bahnlänge beträgt so zwischen 50m-250m.

Fußballgolf scheint in der Welt noch sehr jung zu sein und weltweit gibt es vielleicht nur ein paar hundert Anlagen. Also ganz schön exotisch! :-)

Lustigerweise gibt es sogar Fußballgolfverbände, in Deutschland gibt es den Deutschen Fußballgolf Verband (sic!) und sie veranstalten sogar Turniere. Was es nicht alles gibt! xD

Da es noch kein einheitliches Taggingschema für die Fußballgolfanlagen selbst gibt und auch keine Wikiseite existierte, hab ich mir spontan was ganz einfaches ausgedacht:

leisure=soccer_golf

Das ist in Anlehnung an leisure=golf_course und leisure=miniature_golf.

Ich war auch so frei, ein paar Anlagen in der Datenbank auf dieses Schema umzuschreiben (es war etwas chaotisch), aber natürlich nur dann, wenn ich mir auch sicher war, dass es tatsächlich eine Fußballgolfanlage ist (nix automatisch und so). Ich will ja nix kaputt machen! :-)

Seit vielen Jahren hat www.openstreetmap.org eine ziemlich schlichte Legende in der Seitenleiste (für die Ebene »Standard«).

Ich bin es von ausgedruckten Karten ja gewöhnt, dass es eine (möglichst) vollständige Legende von allen Karten gibt. Doch hier scheitert die Hauptwebseite von OSM. Die Legende hat leider nur die allerwichtigsten Straßen, dann noch ein paar Flächenfarben und nur drei (!) Symbole. Gerade das Fehlen der meisten Symbole ärgert mich am Meisten.

Leider ist diese Legende auch teilweise veraltet oder fehlerhaft, weil z.B. die Flächenfarben nicht stimmen. Schraffuren fehlen total.

Daher will ich Abhilfe schaffen. Auf https://wiki.openstreetmap.org/wiki/Standard_tile_layer/Key habe ich eine (englischsprachige) Seite angelegt, auf der die ganzen Symbole, Linien und Flächenfarben im Detail erklärt werden. Sie ist schon ganz schön lang geworden und ich mir ist klar geworden, wie komplex die Standardebene mittlerweile schon geworden ist. Aber ich hoffe doch, diese Seite ist jetzt schon hilfreich.

Die Wikiseite ist alles andere als vollständig, und es ist schwer, überhaupt mit den ganzen Updates hinterherzukommen. :D Natürlich bist du (ja, du!) willkommen, die Seite zu verbessern, falls du dir wirklich so viel Arbeit machen willst.

Ich habe vorgeschlagen, diese Wikiseite auf der Homepage zu verlinken, damit sie nicht nutzlos und ungelesen im Wiki vergammelt. Langfristig wäre es aber vielleicht besser, die Legende automatisch zu erzeugen, was ich auch vorgeschlagen habe.

Was denkst du dazu? Du kannst ja gerne deinen Senf dazu in Issue 1307 geben. :-) Und wenn es erstmal auch nur gelingt, die Wikiseite zu verlinken, wäre das schon ein Gewinn. :-)

Hallo du da! Freut mich, dass du dich auf meinem Blog verirrt hast.

Das ist mein erster Blogeintrag auf www.openstreetmap.org und gleichzeitig mein erster Blogeintrag meines Lebens.

Ich stelle mich erstmal vor: Ich bin jetzt schon seit vielen Jahren aktiv auf OSM und kartiere so dies und das. Hauptsächlich Orte, bei denen ich persönlich war. Ich spreche Deutsch und Englisch. Ich habe mich OSM angeschlossen, weil ich davon überzeugt bin, dass die Welt gute Open-Data-Weltkarten braucht. Meiner Meinung nach sollten Kartendaten grundsätzlich uneingeschränkt nutzbar sein, aber leider zieht uns das Urheberrecht bzw. Copyright immer noch einen Strich durch die Rechnung. :-(

Ich bin froh, dass es OSM in meiner Gegend schon so weit geschafft hat und dass es so viele Menschen gibt, die alle gemeinsam an einem Strang ziehen. Das Internet ermöglicht uns Menschen Dinge, die vorher undenkbar gewesen wären, und für all die bereits geleistete Arbeit danke ich der OSM-Gemeinschaft. :-)

Im OSM-Wiki habe ich auch so einiges schon geschrieben. Hauptsächlich nur Aufräumarbeiten. Meine größte Seite bisher ist der Versuch, eine etwas ausführlichere Legende für die Standardkarte zu machen (auf Englisch): https://wiki.openstreetmap.org/wiki/Standard_tile_layer/Key

Warum ich erst jetzt in diesem Blog hier schreibe? Hmm, keine Ahnung, wohl zu faul oder so oder ich wusste nicht, was ich schreiben soll.

Für das Mapping bin ich etwas an exotischen, seltenen, und evtl. schwer zu kartierenden Dingen oder Orten interessiert. Ein Beispiel dafür sind öffentliche Bücherschränke (siehe die großartige Wikiseite hier: https://wiki.openstreetmap.org/wiki/Tag:amenity%3Dpublic_bookcase). Noch besser, wenn ich was finde, was noch nicht mal ein einheitliches Tagging-Schema für etwas gibt, dann könnte ich nämlich Pionierarbeit leisten. :-)

Diesen Blog werde ich (vermutlich) für folgende Themen nutzen:

• Interessantes oder lustiges aus meinem Mappingaltag
• Exotische Dinge oder ungewöhnliche Orte
• OSM-Karten auf aufgestellten Schildern (ich bin froh über jeden neuen OSM-Nutzer)
• Meinungen zum Thema OSM
• Was ich sonst so zum Thema OSM treibe

Mapping deep in the heart of Porchester Gardens, Mapperley (named after the 3rd Earl of Carnarvon, who sold the land) (from ‘Baron Porchester’, his 1st title), and here is a little of what some of it looks like:

Just around the corner from where I took that view is the bungalow of a chap that used to have an Ash Tree in his garden. Now I love Ash Trees, and I think that many other Englishmen think the same.They are unique for having young branches that are very straight & supple and thus are perfect for making arrows (classically a yard (900cms) long). It was English arrows married with the Longbow that saw victory for Edward III at Crécy, Poitiers & Henry V at Agincourt. However, Englishmen may love them, but French aristos & bureaucrats do not.

This Porchester Gardens chap’s Ash Tree grew & grew until it was overhanging his bungalow & stuff and the local council told him on threat of law suit to cut it down. It broke his heart, but this is the Ash Tree today:

As an intelligent chap he found a humorous way of celebrating the event by giving his home an appropriate name:

شروعی جدید

بعد از اینکه از نقشه کشی گوگل مپس به خاطر مسائل پیش آمده پس از وارد کردن حدود بیش از پنجهزار مورد دلزده شدم تصمیم گرفتم تا از فرصتی که نقشه ی رایگان (که امیدوارم تا ابد رایگان بماند) در اختیار همگان قرار داده برای تکمیل روزانه ی اطلاعات و جزییات نقشه ای که بدون همکاری جمعی افراد مستعد و سختکوش که بدون هیچگونه چشمداشتی سعی در تکمیل نقشه دارند اصلا قابل تصور نیست و نیاز به بودجه های کلان اقتصادی و دسترسیهای بسیار سخت به اطلاعات انجام شده ی قبلی که گاها سالها از عمر آنها می گذرد و در شرایط کنونی کم استفاده و در مواردی بیهوده است را مرتفع نموده و با ایجاد بستری بر روی وب و همکاری مردمان علاقمند روز به روز تکمیلتر از گذشته می شود. کار بر روی نقشه ی گوگل را زمانی آغاز کردم که تنها جاده های بزرگ و اصلی کار شده بود و نام هیچیک از آبادیها ی استانها یا وجود نداشت و یا بسیار کم و ناقص بود .در ابتدا به خاطر نبود اطلاعات از مناطق گوگل با اطمینان کامل تمامی اطلاعات وارد شده توسط مرا بدون معطلی منتشر می کرد و کار بسیار بزرگ نامگذاری آبادیهای شهر زنجان از روی اطلاعات مربوط به استانداری و تقسیمات کشوری را انجام دادم کاری زمانبر و سخت با عکسهای هوایی با وضوح بسیار بد. اوضاع خوب پیش رفت و توانستم نام بسیاری از آبادیهای استان زنجان را وارد کنم ونقشه ی روی سرور گوگل جلوه ی خاصی یافت .پس از اینکار شروع به ترسیم جاده های آبادیها کردم و در برخی موارد اطلاعات جمعیتی روستا ها را نیز وارد نمودم.پس از مدتی میشد نتیجه ی زحمات خود را بر روی نقشه دید و لمس کرد. بعد از ترسیم جاده ها شروع به کار بر روی نقشه ی خود شهر زنجان بعنوان مرکز استان نمودم همانگونه که خود میدانید با عکسهای کم وضوح توانستم خطوط خیابانها را وارد و تا جایی که میتوانستم نقشه را تکمیل کردم شهرک به شهرک کو چه به کوچه . تا اینکه میزان ویرایشهایم از چهار هزار و پانصد فرا تر رفت . اوضاع خوب پیش میرفت و نقشه ی قابل قبولی به دست آمده بود تا اینکه به هنگام کار بر روی جنوب غربی شهر زنجان به اطلاعات ناقص و غلط و پر از ایراد یک کاربر رسیدم که الحق و و الانصاف تا توانسته بود در خراب کردن آن قسمت از شهر هیچ دریغ نکرده بود. چون عادت دیرینه داشتم تا تمامی کارهایی که انجام میدادم را با توضیح کوتاه مختصری همراه سازم شروع به تصحیح و دو باره سازی کار های ایشان کردم تا اینکه یکروز متوجه شدم اکانتم دچار مشکلی شده و من اعتماد شرکت گوگل برای کار هایم را از دست داده ام. و بعد از هر ادیت متوجه میشدم که کارهایم بایستی بصورت تعلیقی دنبال شوند. و به طور زنجیر وار همه ی کارهایم به تعلیق کشیده میشدند. ضمن نامه ای به گوگل اعتراض نمودم که در کمال تعجب با این جواب در کامنتهایم مواجه شدم که همه ی کاربران میبایست به ترسیمات یکدیگر احترام بگذارند. با ارسال نامه ی دیگری به آنها گفتم که کارهای کاربر قبلی تو ام با اشتباهات فراوان است . ما هیچ نتیجه ی مثبتی نگرفتم که هیچ بلکه ویرایشهای جدیدم میبایستی توسط دو کاربر دیگر تایید گردند.... از شاهکارهای کاربر مورد نظر ایجاد یک راه تر و تمیز شمال جنوب از وسط شرکت ایران ترانسفو بود که حتی یک آدم کور با لمس کردن نقشه میتوانست ماجرا را بفهمد چه رسد به من که خود در این شهر زندگی میکنم و نسبت به تغییرات آن حساس ام. خلاصه که به مدت چندین سال گوگل را رها کردم و در این مدت کاربران نقشه کش حرفه ای تر و بهتر از من کار شهرمان را دنبال کردند و آنها نیز در این قسمت از شهر مجبور به سکوت شدند تا اینکه عکسهای هوایی بهتر و شفافتر درستی ادیتهای قبلی من و نادرستی ویرایشهای کاربر مورد نظر را آشکار کرد . اما دیگر دیر شده بود و دیگر میلی به همکاری با گوگل را نداشتم و هر از چندی خطی یا نقطه ای ترسیم و یا لا اقل ترسیم دیگران را تایید و بررسی میکردم تا اینکه یکماه پیش خواستم تا نقطه ای را اضافه کنم نوشت که دیگر ترسیم چند ضلعی را برداشته و کاربران تنها مجاز به خط و نقطه هستند.در تصمیم خود جهت کنار گذاشتن گوگل مصمم شدم و دیگر تمایلی به همکاری با آن موسسه را ندارم.

Finally I managed to import my hiking trip to mount Shir Kuh near Yazd in Iran into the OSM database.

So far, there was (at least to my knowledge) no map of the 2 hiking paths to the summit and the hut available. I hope that hiking enthusiasts visiting Iran in the future will have it a little bit easier to hike to Shir Kuh!

BTW: A guide is not really necessary (With the GPS map now anyways!)

Unfortunately my GPS accuracy was awful, but I tried to interpolate it with the satellite imagery.

Happy hiking in Iran :) (Yes, you should definitely visit this country!)

Might depend on what exactly one considers a point of interest, but looking at some common keys:

we get around 17.8 million features that could be potential landmarks or points of interest.

Just counting points that have names, we get around 12.9 million features.

Maybe there is a better way of finding out, but here's a new conversation starter at your next mapping party!

Hi everybody,

I'm a newcomer enthusiast focused mainly in editing in Tirana (Albania) and Diber (Albania). It seems like there is a greater need for projects like OSM in Albania since foreigners that visit the country, but also locals find it hard to find directions to move around cities.

I really hope to make further steps for the OMS community in Albania in order to grow the project even more.

Cheers,

Recently, I wrote about [how you could use government road data to improve OpenStreetMap](www.openstreetmap.org/user/joost schouppe/diary/39250). Here's a move in the other direction.

As an employee of the city of Antwerp, I was involved in the recent 'validation' of the Road Registry (Wegenregister) for our city. This registry is managed by the central Flemish government, but final responsibility for the content is with the municipality. Validation means the central government gives us a new dump for us to check for errors. This way of working is only a temporary situation: in the future, we will be live editing in the central database itself.

Some background

There's an amazing amount of cleanup left to do, but we decided to focus on the completeness of the main road network. Before, we did this by comparing with our own city registry of roads. But that is not being updated anymore. So for the first time, we used OpenStreetMap for the validation. Using FME, we identified roads which exist in OSM, but not in the Road Registry. We excluded service roads and "slow roads" (paths, tracks, cycleways), as these are less of a priority right now.

Next time, we will also look at roads that are in the Road Registry, but not OSM. In some case, the lack of road in OSM is really an indication of an error in the Registry. For example when a road has been closed, and the government somehow missed that. This is more work, because the Road Registry contains a lot of little bits of "roads" that are really just driveways. Because nobody cares about them, they aren't in OSM. But they are quite hard to filter out from the Registry data.

The results

The cleaned up dataset of roads that are in OSM and not in the Registry was really quite limited. Only 138 situations needed manual review. Of those cases, 32 were a simple matter of slightly different geometry. For example when OSM mapped the road as a polygon, which we didn't really take into account. We identified 33 cases where the Road Registry was clearly wrong. Then there were 31 cases that looked like they shouldn't have been in the selection anyway: they are private driveways, parking aisles, tramways. About half of those needed a fix in OSM. But the "tramways" were actually dedicated bus roads on top of tramways.

Most of the "mistakes" detected in OSM were caused by larger geometry issues. Sometimes the centerline of a road is debatable, but in most of these cases OSM could be improved, sometimes vastly. These were most often roads that hadn't been touched in years. Only in a couple of cases was OSM really vastly wrong. This happened when the city reorganized streets, and somehow, nobody noticed. Most striking was the Troonplaats, which is a quite popular square. In several cases, OSM had already been corrected in the month or two between data download and final analysis (though to be honest, some of those were fixes of mine). A few mistakes were caused by errors in or outdated road classification.

There was one striking case (pictured above), where we were convinced OSM was wrong, but we apparently missed a big change in the road geometry. Fortunatly there was a [Mapillary sequence], of course one of the 1.1 million pictures uploaded by filipc. Even though the aerial photography in Flanders is excellent and recent, the only place this road shows up is on the OSM map.

Have a look

You can have a look at the cases here. There's a bit of work left on the cases with a difference in geometry. The easiest way to get the Road Registry into your editor is with this (slightly outdated) WMTS:

https://api.mapbox.com/styles/v1/joostschouppe/cir6gwq2p0016cjlyx6e1b1cc/tiles/256/{z}/{x}/{y}?access_token=pk.eyJ1Ijoiam9vc3RzY2hvdXBwZSIsImEiOiJjaWh2djF1c2owMmJrdDNtMWV2c2Rld3QwIn0.9zXJJWZ4rOcspyFIdEC3Rw

You can contact me to get the FME models we used to identify these roads - they aren't very complicated. You could easily do similar things in open source software.

I'm happy to announce a time limited Overpass API test drive that is based on the official 0.7.53 release + some experimental features. The server is updating continuously like the main instance, but doesn't have so called attic data.

That's a great opportunity to try out your favorite queries and post your feedback below

Switching to the test drive instance

In overpass turbo, go to "Settings", enter the following server address, hit the save button and you're all set for testing.

http://dev.overpass-api.de/test753/

(sorry, http only at this time, i.e. you need to run overpass turbo via http as well)

Remember: you can always switch back to one of the 3 public servers listed in the "Server" drop down list, in case there's some issue with the test drive.

A few examples:

(you need to switch to the dev server first)

• 'Ring of fire': http://overpass-turbo.eu/s/iBF
• Find all 'segments' of a street, even containing gaps: http://overpass-turbo.eu/s/iBH
• Global xmas-features: http://overpass-turbo.eu/s/iFM

Have fun!

Emmor (account Palolo) asked some questions in an OSM message, I've put my response here as it may be of general interest.

On 2016-09-26 22:32:47 UTC Palolo wrote:

Ben, Thanks for your contributions to OSM, especially for the rivers you have cleaned up on the west coast. I also just came across your spreadsheet tracking users and find it fascinating.

I was wondering if you could convert your notes into 3 categories of mappers: 1) Imports, 2) Mappers, 3) Combination mapper/importer ?

That's a good question, I've considered trying it, but it can be difficult to tell them apart, or it requires individual detective work that I just haven't gotten around to. Generally, for the import or part-import accounts, I've put the title of that import in the "Grouping" column.

If they have added millions of nodes, and there is nothing about importing in the "Where, What" or "Grouping", it means I haven't been able to figure out if they are an import account or not. For example the Japanese accounts, "Tom_G3X" and "ikiya" and "yamasan". They are probably imports(?)

I've also put the account name in bold (like katpatuka and Heinz_V) if they have contributed millions of features without any obvious importing. Anyone who belongs in this category that I've missed, please let me know!

Also have you thought about gender classification?

I've thought about it, but it is also very hard to tell. Very few account names/images are clearly gendered, and nearly all those that are, by name or image, appear male.

It appears to me that there are very few female top contributors. I wonder why this is since it is open for anyone to edit.

Probably for the same reasons that cartography and technology in general is so male, cultural bias encourages it for men and encourages other things for women.

The top-ranked female account that I know of is "ediyes", a Mapbox mapper at #137/88 (more than 88K changesets!). However, it's entirely possible that some of the mysterious accounts in the top 100 are female. In the top 1000, there are many, including other female mapboxers (dannykath, karitotp, samely...) and the Queen of #MapLesotho, tshedy.

One editor that has been super active over the past 9 months is "Aiko Nakata", which is a Japanese female-only name. Also "Febrina Dewi" and "Fatisya Ilani Yusuf" and "asti_shinoda", all women I believe, were the top-ranked contributors to #MissingMaps last year, all from Indonesia, an amazing amount of mapping work.

Mancher User meint, er müsse ein möglichst großes Gebiet abdecken. Dabe quält er sich oft mit einem schmalen Spalt zur nächsten passenden Fläche. Korrekturen und Ergänzungen werden dann für ein unübersichtliches Gebiet angezeigt. Schnell sind wir bei der hundertsten Änderung angelangt. Das System ist überfordert, die Historie anzuzeigen. Bitte mappt statt dessen lieber jeden Kartoffelacker einzeln für sich. Wenn dann den nächsten Jahren dort Rüben und danach Roggen angebaut werden, wird dies kaum schnell genug verändert, immerhin es wäre dann machbar. Noch schlimmer ist es bei den Multipylogonen und Mega-Multipylogonen; ganze Landstriche werden durch diese Versiegelung von der Aktualisierung ausgeschlossen. Wenn Inseln nötig sind, ja bitte; aber dann so klein wie eben möglich. Eine offene Datenbank muss offen bleiben!
