The Denver Regional Council of Governments (DRCOG) has purchased over 1M building footprints for the greater Denver area. We're going to add them all to OpenStreetMap!

OpenStreetMap is an open map of the world that anyone can edit and freely use. In support of open data, The Denver Regional Council of Governments is making over 1M building footprints with 6cm accuracy available for importing to OpenStreetMap.

To participate, see the links below under Resources + Instructions and visit the OSM-Colorado meetup page to find the next in-person import-a-thon.

Find us in the #colorado channel of the OpenStreetMap US slack workspace.
