The one in the south does not cast the sadows I would expect to see and it does not look like similar dark roofed buildings nearby. I think the one in the north is a tree (probably without leaves) it may be a building, but if so the footpint should be significantly smaller. Cross referencing bing is useful here. Hope this is informative.
