MULTIGRID CELL SHAPE EVALUATION IN DTM FILTERING OF MOBILE LIDAR POINT CLOUDS
Point cloud Mobile LiDAR Digital terrain models Filtering Delaunay triangulation
2018/11/9
The georeferenced information acquisition for large scales digital terrain models generation is usually a rather time-consuming and costly process. The use of point clouds gathered by mobile LiDAR sys...
AUTOMATIC DTM GENERATION FROM LASER-SCANNING DATA IN RESIDENTIAL HILLY AREA
LIDAR Geodesic dilation image reconstruction
2015/9/28
Airborne laser scanning systems provide high quality 3D point clouds from the earth’s surface. A Digital Surface Model (DSM) is
provided from the LIDAR data after removing the outliers from the point...
Digital Terrain Models (DTM) are frequently used to make important decisions. In order to judge these decisions DTM quality must
be known. The quality of a DTM consists of several components like pre...
