Towards accurate determination of surface height using modern geoinformatic methods : possibilities and limitations

Auteur :
GAO, J.

Description :
Over recent decades several modern geoinformatic methods have emerged, including global positioning system (GPS), interferometric radar, and airborne laser scanner (ALS) or lidar. In conjunction with the conventional survey and photogrammetric method, they have found wide applications that demand varying levels of accuracy. In this paper, the principles of each method are briefly summarized. The discussion then concentrates on the accuracy level achievable with each method.
