A valid footprint but it should have been squared. After mapping buildings, please remember to square their corners. Most buildings have square corners because that's easy to build. Unless the building is clearly a different shape then it's best to assume that the corners should be squared. In the iD Editor, use the `Q` key to square the corners.
