Hello, the vast majority if not all these footprints represent buildings. They'd be even more accurate if they were generally smaller. Exclude the shadow a buildings casts on the ground from its footprint. Mapping footprints slightly smaller than pitched roofs accounts for the overhang and helps prevent data issues in dense areas. Thank you for your contribution. ---
