Dear all, The mapmakers using Inkscape / photoshop on wikipedia (WP:GL/M) to generate the articles' maps currently work file after file, which generate scores of background / data duplication which are increasingly hard to manage. Also, we are willing to know : is there any ongoing project/system/extension to create a kind of free google maps where we —graphists— may **create and edits** encyclopedic maps in the clouds ?
I noticed : * http://toolserver.org/~osm/styles/ - display many layers, no edit functions. * http://www.mediawiki.org/wiki/Category:Map_extensions - don't seems to have such extension. * the online editing tool is missing ?
