Abstract
NASA, NSF and USGS jointly conducted LIDAR surveys to acquire numerous surface points with high densities over the Antarctic Dry Valleys and its vicinity. The huge set of the points unusually includes many blunders, retaining large variation of the point densities. Hence, to reduce the undesirable effects due to these characteristics and process the huge number of points with reasonable time and resources, we developed an efficient, robust, nearly automatic approach to DEM generation. This paper reports about the application of this approach to generating high-resolution precise DEMs from the Antarctic LIDAR surveys and the evaluation of their accuracy.
