Overall you've improved the accuracy of the footprints in this changeset. Generally footprint size has been reduced so they no longer envelope the shadows cast by buildings. Beware that objects can shade themselves i.e. there are dark and light parts of roofs depending on their shape and sometimes the (shaded) wall of a building may be visible if the imagery is taken at an angle.--- you appropiately changed the shape of footprints from square to round. You did this by deleting and remapping the footprints but you can actually just select square buildings you think are round and press (o) to circularise them, then move (m) and scale [shift+(-/+)] them to make them accurate instead of mapping from scratch. The circularise function only requires a minimum of 3 nodes. You deleted some valid footprints here. I previously mapped some of these becasue they are likely buildings under construction. Thanks for your contribution.
