Testing map accuracy requires the identification of map features with those that are easily visible or recoverable on the ground as well-defined points for comparison. Features which are shown on a map but do not physically exist in the real world or cannot be easily measured cannot be used.
For horizontal accuracy, the intersection of two roads, the corner of a building, benchmark ...
