This used to correctly go to MapDust for a given location. However at some point the Permalinks changed from WGS84 decimal degrees to, I believe, Spherical Mercator meters. (I guess those Permalinks aren't really that "permanent" if they changed coordinate systems).
Is there a way to have MapDust accept WGS84 decimal degrees like the other services that the OSM wiki links to?
I've fixed the OSM wiki template code to do the conversion so that MapDust links work correctly.
