Hi, The vast majority of footprints represent buildings. Some footprints could be slightly shorter. Use the shadow to inform the size and shape of footprints you map. --- The arrow-head footprint is inaccurate, becasue you traced the roof instead of using it to inform you mapping of the footprint. See https://wiki.openstreetmap.org/wiki/Roof_modelling#Typical_errors_in_the_interpretation_of_roof_geometry_from_aerial_images --- Thank you for your contribution. If you want to experience the OSM community or to get timely feedback from other mappers; I recommend that you attend a mapathon. You can find events here https://osmcal.org/
