I love the above example. Mapswipe is a great tool for large scale mapping of the type that HOT and Missing Maps does often.
Heidelberg University has done some great early work to visualize the results and projects in MapSwipe. This is still a work in progress but its a great example of the Missing Maps consortium members all pitching in and doing a little bit of work for a greater good, just like OSM. http://mapswipe.geog.uni-heidelberg.de/ On Tue, Mar 28, 2017 at 9:00 AM, Violaine Doutreleau < [email protected]> wrote: > Hi all, > > Just a quick message to share my point of view : mapswipe allows way more > people to take part into Missing Maps than OSM, even though it's not direct > mapping...Anyone who doesnt't want or doesn't know how to map in OSM can > take part in this effort.
