Very useful when surveying and mapping - given the astronomical prices of real estate.
better to use a laser range finder for this - gps wont cut it
Sort of True. Survey quality gps will give you repeatability - the offset will be consistent and the distance between two points over a few Km will be accurate. But the position wrt to a standard survey may be way off. Thus results (conventional survey or gps) are open to interpretation.
