The Ground Area in Zhejiang Province Airborne LiDAR data Processing and DEM Production Practice
In order to update elevation of the plain areas in fundamental surveying and mapping products, a project about airborne LiDAR data processing was implemented for the acquisition of DSM and DEM with higher precision. In this article, the main key technologies are studied in TerraSolid software, including the height accuracy LiDAR point cloud data control, point cloud classification requirements and how to use the filtering feature lines to control DEM precision in some area without point cloud data key such as non-regional aspects of point cloud data.
