I cc'd the talk-ca list, as it's a FAQ

No, not yet.  RichardF (who works on development of Potlatch, says that for
version 3 it will be available).   But for now JOSM works well for it.
There is also the option to right-click on the layer and choose 'change
resolution'  as this will produce a different map scale render of Toporama.

BTW, the background is the GeoBase Aboriginal Lands. ... (i'll announce it
later)

BTWW,  Empress, Alberta is also proving to become the best mapped place
