摘要

In the process of producing digital elevation model with airborne LiDAR, different procedures are required for products of different specified level. When producing products higher than level two, it requires manual editing to assure the correctness. In this study, several issues of manual editing are investigated. Ten map-sheets covering five major land-cover types are selected for the comparison. The area of each map-sheet is about 2.5 km by 2.5 km. Preliminary results show that automatic filtering with proper selection of parameters specified for different part of the map may have an effect of saving 20% of time for subsequent manual editing. For the same map-sheets, manual editing by different operators may produce different results and the time required is significantly different. In general, the height difference of the DEMs from two individuals gives a standard deviation of 25 cm.
