Mapping

• There are  Music-Flashmobs, Timefreezing-Flashmobs, and Students-Flashmobs – but what about a Mapping-Flashmob?
• User k1wi has published tag usage statistics for the tags exit_to=* und destination=* in highway exits in the USA. k1wi created similar tagging statistics for roads in Spain.
• JOSM validator reports 6,432 errors in Nukus, Uzbekistan. How did this happen?

Community

• [1] Ramani Huria published a “Year of Edits” video showing OSM growth in Africa between 2013 and 2015.
• User MeisterLampe from Brazil is happy. His new home town of Blumenau in southern Brazil is better mapped on OSM than on Google. However, as houses and house numbers are missing, he had to start on a more detailed mapping project and he’s pleased with the community’s support (post in German – automatic translation to English).

• SK53 reports about news channels thinking that Google owns OpenStreetMap.
• The Dutch community is discussing public transport data in their country and comparing it to nvloket data. A lot of data is still in an old standard.
• Pierre-Yves Berrard discovered an area on the Bano rendering which is far too busy to be useful. Christian Quest will have a look whether it is a bug. Other proposed to render the data in a different way. (via talk-fr)

• The Asia Foundation (TAF) organised an OSM workshop for the region of Dumaguete in the Philippines.
• Stefan Keller created a Wiki page for “Geohashing”. Geohashing is an outdoor activity inspired by the web comic xkcd. While Google Maps are often used for Geohashing, among the many “achievements” in the game there is an OSM-Achievement for contributing to OSM.
• Anonymaps shows why tagging roads in the US using only ref won’t work.
• Daniel Koć is asking on the Talk mailing list about the goal of the project “main page” openstreetmap.org. He proposed uMap-like functionality on GitHub, which was faced rejection. Steve Coast commented on the topic in the discussion.

• Luis Dinger created a nice 3D view of Manhattan and other cities with Cinema4d, OSM and other data sources. Unfortunately in a Guardian article about these maps “Google’s OpenStreetMap” is cited as a source (since corrected).
• Enjalot posted a web app with a concise interactive visualization of different map projections (also see “The True Size” for exploring the effects of the Mercator projection).
