[OSGeo-Discuss] online open source polygon mapping, like OSM?

[Nitin Gadia]

Please help!!


Does anyone know an open online mapping platform like openstreetmap that
does polygons (OSM only does lines)?

Basically, I'm envisioning something where someone can add polygons such as
historical nations, and then be able to animate them. I should be able to
type in, say, "1900" and see the way the world was then. I can then edit a
map, changing and adding polygons, and their colors and metadata. I should
also be able to view areas by, say, population density and other statistics.

The closest thing I've found is "click2map", which is not opensource.
Something needs to be created just like it. Try it out, and create a
polygon:

I want to help create an open historical map of the world. Check out the
work I've done so far:

If this is not available, I will do everything I can to help build it!


Thanks,
Nitin
