All footprints here are valid and the vast majority are accurate. Thank you for your high quality conrtributions. I think that the C shaped building is actually a rectange with a ^- roof cross section. The T shaped building I think could be better mapped as two footprints becasue I cannot see the same diagonal joints in the roof like the building to its south. I made some modifications to the footprins in this changeset and uploaded them in Changeset: 164572759 & Changeset: 164572787.
