I'll change the project name to reflect that the import is on hold. As a
local mapper, if you want to take a lead on the Toronto import that'd be
I did review some of DannyMcD's edits last night
(Mississauga-Brampton-Vaughan) and to be honest was rather disappointed
with the quality. It appears Danny chose to import only new buildings (i.e.
residential homes mostly), leaving most of the existing hand-traced
non-residential building outlines in OSM untouched. That's unfortunate, the
dataset offers some really good data and leaving half of it behind makes it
more difficult to revisit in the future.
In my edits (Markham-Scarborough-East York) I was aiming to replace as many
existing geometries with outlines from the import as possible. I think
that's what we should be trying to do going forward.
Looking forward to your comments and discussion.
