Building Footprints
Building footprints and heights come from OpenStreetMap worldwide and from national open datasets in Switzerland and France. Where a national dataset has a building, it takes precedence over OpenStreetMap. OpenStreetMap fills in everything else, so there are no gaps at the borders.
