You mean triangulation? My GPS (garmin oregon 550) comes so close to
supporting this natively with its built in compass, but falls short.
It has a mode which lets you point at an object, then estimate a
distance, then it projects a waypoint. All it needs is the ability to
point at the same object from two different locations, then
triangulate.
