DEM (Digital Elevation Model), DSM(Digital Surface Model), DTM(Digital
Terrain Model), Photogrammetry.
Abstract
Obtaining and managing accurate information is most important in
the 21st century. Airborne Laser Mapping System (ALMS) provides better
accuracy than other photogrammetry data. The study shown in this paper
suggests the superiority of ALMS above other photogrammetry methods.
This paper deals with ALSM which is being rapidly developed last
few years provides us high density and accurate DTM and DSM and
furthermore, the way ALSM can contribute to the study NGIS
Implementation.
