Ground control factors need to get on the ground for consistent outcomes. Beware when choosing 'normally taking place' ground control points. Some attributes (such as parking rooms or the corner of buildings) might be as well repetitive to be beneficial. Shadows are alluring - yet they may move also while it takes to fly a site.
