Evaluating the accuracy of digital elevation models derived from spaceborne satellites
In Jordan, Sultan Al-Harbi (PhD student) and Kevin Tansey collected several thousand height points using the kinematic mode of the SPLINT differential GPS (Leica GPS-500 SR20). They managed to find a secure location (a police station) in the middle of the desert for siting our base station, attached a Rover antenna to their vehicle and set off. Three days later they had collected million of very accurate height points from which to evaluate the accuracy of digital elevation models that we have derived from spaceborne satellites.
