[Talk-ca] Building Import update

[john whelan]

So how would you tackle it?

Adding buildings with JOSM and the buildings_tool is possible, I think
Julia tried to whip up some interest with the 2020 project.  Unfortunately
mapathons using iD and new mappers for some reason don't work too well for
buildings. They do work fine for adding tags though.

I seem to recall March 2nd is some sort of student GIS day and we can
expect something to happen in GEO/GIS week whenever it is.  I'd prefer
adding tags to existing outlines rather than having to clean up buildings
added with iD.

If we go back in time to the Ottawa import and the licensing issues I seem
to recall a Toronto mapper submitting the Toronto Open Data License to the
legal working group which implies at least one Toronto OSM mapper was after
the Toronto Open Data.

My feeling at the moment is there is a suggestion that "cleaning" the data
up then some sort of team approach in a particular area would be acceptable
but how you put it together I'm not sure.

Suggestions please

Thanks

Cheerio John
