If you want to take a look at this kind of data, Toronto's 3D massing data set is derived from LIDAR. It's what we have for building outlines, and it's not bad at all: https://www.toronto.ca/city-government/data-research-maps/open-data/open-data-catalogue/locations-and-mapping/#db07630f-252d-f7ae-2dff-8d0b38ec6576 cheers, Stewart _______________________________________________ Talk-ca mailing list Talk-ca@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-ca
