Hello,
Four months ago new maps were launched at
https://maps.wikimedia.org. Russian, Italian, and other GeoHack language Wikipedias have switched to it, as well as WikiVoyage community. I have been working closely with the creators of the current mapping projects like WikiMiniAtlas and WIWOSM (Daniel Schwen, Kolossos/Tim Alder, Magnus, Simon Legner, Sylvain, and others) on trying to merge them together into one platform.
I believe our maps are now stable and capable enough to serve all users of GeoHack, and can really use community's help to migrate it. Migration is very simple - modify Template:GeoTemplate and MediaWiki:GeoHack.js as was done here:
Eventually I am hoping that we won't need to use this complicated approach, once Kartographer extension is finished.
EXAMPLE:
Please email if you have any questions. Thanks!
P.S. You might like my other project - interactive graphs, available on all wiki. Feedback is welcome.
