Building footprints

As of September 20, 2024, you can find the data for the building footprint layer using the [Quebec Building Repository] sheet (https://www.donneesquebec.ca/recherche/dataset/referentiel_bati). You will have access to improved data with increased territorial coverage. Therefore, the “Building Footprints” product sheet will be removed from our directory for a simplified experience. * * * The building footprint layer is the result of a data exchange partnership between Natural Resources Canada (NRCan) and the Government of Quebec. It will be improved as data becomes available. The Government of Quebec, wanting to optimize the use of Light Detection and Ranging (lidar) data acquired in recent years, has partnered with NRCan in order to extract the polygons of buildings in Quebec. Airborne lidar data from Quebec is processed using automatic extraction algorithms developed by NRCan, which makes it possible to obtain a layer of building footprints from a bird's eye view, in the form of vector polygons. The data is normally broken down by lidar project. Since extractions are carried out automatically, no quality control has been carried out on these data sets. Work to improve the geometries and to improve the attributes is currently under way.
