Shared publicly -Heard of #ChattyMaps? Its a wonderful website that takes data from #maps and other sources to create a best guess estimation of the makeup of #sound composition at that location (eg 20% industrial, 80% wildlife etc). Really neat. http://goodcitylife.org/chattymaps/index.html

This site is AWESOME! Reminds me a little of http://listen.hatnote.com/ where you can "listen" to Wikipedia.

Windows 10 -
Windows 10 is an ever-evolving operating system, and its latest iteration was released this week in the form of Insider Preview Build 14291 for both PCs and smartphones. Build 14291 is notable for a number of reasons, with the most prominent one being the addition of extensions support in the Edge browser.
Many users lamented the fact that

The improved resolution of the new gravity map suggests a new explanation for how some features formed across the boundary that divides the relatively smooth northern lowlands from heavily cratered southern highlands. Also, the team confirmed that Mars has a liquid outer core of molten rock by analyzing tides in the Martian crust and mantle caused by the gravitational pull of the sun and the two moons of Mars. Finally, by observing how Mars' gravity changed over 11 years – the period of an entire cycle of solar activity -- the team inferred the massive amount of carbon dioxide that freezes out of the atmosphere onto a Martian polar ice cap when it experiences winter. They also observed how that mass moves between the south pole and the north pole with the change of season in each hemisphere.
The gravity field was recovered using about 16 years of data that were continuously collected in orbit around Mars. However, orbital changes from uneven gravity are tiny, and other forces that can perturb the motion of the spacecraft had to be carefully accounted for, such as the force of sunlight on the spacecraft's solar panels and drag from the Red Planet's thin upper atmosphere. It took two years of analysis and computer modelling to remove the motion not caused by gravity.
"With this new map, we've been able to see gravity anomalies as small as about 100 kilometers (about 62 miles) across, and we've determined the crustal thickness of Mars with a resolution of around 120 kilometers (almost 75 miles)," said Genova. "The better resolution of the new map helps interpret how the crust of the planet changed over Mars' history in many regions."
For example, an area of lower gravity between Acidalia Planitia and Tempe Terra was interpreted before as a system of buried channels that delivered water and sediments from Mars' southern highlands into the northern lowlands billions of years ago when the Martian climate was wetter than it is today. The new map reveals that this low gravity anomaly is definitely larger and follows the boundary between the highlands and the lowlands. This system of gravity troughs is unlikely to be only due to buried channels because in places the region is elevated above the surrounding plains. The new gravity map shows that some of these features run perpendicular to the local topography slope, against what would have been the natural downhill flow of water.
An alternative explanation is that this anomaly may be a consequence of a flexure or bending of the lithosphere -- the strong, outermost layer of the planet -- due to the formation of the Tharsis region. Tharsis is a volcanic plateau on Mars thousands of miles across with the largest volcanoes in the solar system. As the Tharsis volcanoes grew, the surrounding lithosphere buckled under their immense weight.
The new gravity field also allowed the team to confirm indications from previous gravity solutions that Mars has a liquid outer core of molten rock. The new gravity solution improved the measurement of the Martian tides, which will be used by geophysicists to improve the model of Mars' interior.
Changes in Martian gravity over time have been previously measured using the MGS and ODY missions to monitor the polar ice caps. For the first time, the team used MRO data to continue monitoring their mass. The team has determined that when one hemisphere experiences winter, approximately 3 trillion to 4 trillion tons of carbon dioxide freezes out of the atmosphere onto the northern and southern polar caps, respectively. This is about 12 to 16 percent of the mass of the entire Martian atmosphere. NASA's Viking missions first observed this massive seasonal precipitation of carbon dioxide. The new observation confirms numerical predictions from the Mars Global Reference Atmospheric Model – 2010.
The research was funded by grants from NASA's Mars Reconnaissance Orbiter mission and NASA's Mars Data Analysis Program.

A new map of Mars' gravity made with three NASA spacecraft is the most detailed to date, providing a revealing glimpse into the hidden interior of the Red Planet.

There are main 5 highways entering to Tibet, which respectively are Nepal-Tibet ( Sino-Nepal ) Highway, Qinghai-Tibet Highway, Xinjiang-Tibet Highway, Sichuan-Tibet Highway and Yunnan-Tibet Highway, but the last two are closed for foreign travelers. We offer the maps here http://www.tibettour.org/tibet-map/tibet-road-map.html .

This is one of those why-haven’t-we-had-this-all-along kind of updates, but Google Maps has just launched the ability to tag your favorite locations with themed icons. Previously, everything was stars. Stars for work, stars for home, stars for your favorite bowling alley, etc. Now you can make your Maps really feel like your own, and isn’t that really what the Android experience is all about?Google has your back with an array of colorful icons t...
