[Talk-ca] New project with OSM at Statistics Canada

Thu Aug 4 00:01:29 UTC 2016

Do you really want to add 300,000 building outline to the map?  If it was
just the non residential ones I think that is reasonable but adding every
residential house is adding less value.  Can we identify and omit the
obvious single family homes?
