Hi, these footprints are all valid and appropriately squared but oversized. Cross refernece Bing if it makes it easier to see that this is the case. Press f1 while your cursor is over the select mode icon in JOSM for modification shortcuts. I also recommend installing the extrude tool. --- When mapping buildings, please trace the shape accurately. Accurate building footpritns aid population estimates and prevent issues like data overlaps. Zoom in so that you can see the outline of the building and mark the corners carefully. Exclude shadows and yards when tracing the footprint.  Keep in mind that you are looking at the roofs of buildings, but mapping their footprints.  Generally pitched roofs overhang the walls of a building, so a footprint slightly smaller than the roof is accurate. Take care to make contributions that others can build upon. ---Please keep this feedback in mind when contributing in future. Thank you for your contribution.
