Martijn van Exel’s OSM Then and Now compares OpenStreetMap as it was in October 2007 with how it is today, with a slider to change how much you see of one or the other. Amazing how little was mapped back then, especially outside: my own town didn’t appear at all, and even Ottawa was rudimentary.
Quartz takes a look at the Missing Maps project, which I suppose can best be described as a way to jumpstart mapping the unmapped developing regions of the world with OpenStreetMap. What’s interesting about Missing Maps is how it systematically deals out tasks to people best able to do them: remote volunteers trace imagery, community volunteers do the tagging and labelling. There’s even an app, MapSwipe, that gives its users “the ability to swipe through satellite images and indicate if they contain features like houses, roads or paths. These are then forwarded onto Missing Maps for precise marking of these features.” [WMS]
Start with the National Hurricane Center, which has lots of different maps of Hurricane Matthew’s predicted path, weather warnings, rainfall potential and so forth. See also maps from Weather Underground.
Google’s Crisis Map includes evacuation resources—Red Cross shelters, evacuation routes, traffic data—in addition to storm track and precipitation information.
“The OpenStreetMap Community is at a crossroads, with some important choices on where it might choose to head next,” wrote Michal Migurski last month. Identifying three types of map contributors—robot mappers using third party data, crisis mappers responding to a disaster like the Haiti earthquake, and so-called “local craft mappers” (i.e., the original OSM userbase that edits the map at the community level, using GPS tracks and local knowledge), Michal ruffled many feathers by saying that “[t]he first two represent an exciting future for OSM, while the third could doom it to irrelevance.” That’s largely because, in his view, the craft mappers’ passivity and complacency, and their entrenched position in the OSM hierarchy, are impeding the efforts of the other two groups.
With Pokémon Go players turning up outside private homes that have somehow been designated, in game terms, as “gyms,” The Atlantic’s Robinson Meyer asks where exactly Pokémon Go is getting its mapping data from. [Jay Owens]
Arun Ganesh talks about making a multilingual map of India: “Hardly anyone in India even knows that OSM can handle regional languages, simply because its not visible anywhere on the map. After some recent interest from the community in making regional language maps for openstreetmap.in, I decided to give this a shot to make a multilingual place map for India using OSM and Mapbox Studio that I have been playing with recently.”
