A MORPHOLOGICAL RECONSTRUCTION ALGORITHM FOR SEPARATING OFF-TERRAIN POINTS FROM TERRAIN POINTS IN LASER SCANNING DATA
LIDAR morphological reconstruction terrain points off-terrain points DTM
2015/8/13
During the last decade various techniques have been proposed to extract the ground surface from airborne LIDAR data. The basic
problem is the separation of terrain points from off-terrain points whi...
