摘要：Airborne Laser Scanning was used to map Switzerland. Large parts of the project area are in mountainous terrain and all processes had to be adjusted to this challenging terrain to obtain the desired product quality. The required vertical accuracy on hard surfaces was 0.5 m, the achieved vertical accuracy is approximately 0.3 m (1 Sigma). The required point density in the open area was 0.44 Pts/m 2 , the resulting one is almost 1 Pt/m 2 . Among others following factors were critical for the success of the project: optimized flight planning for the data collection in the Alps, adjusted automated filtering algorithms, both impossible without a profound knowledge of the topography. Finally the huge amount of data must be managed carefully and the project management must be supported with appropriate software tools
