Automated DTM Generation in Urban Areas with Airborne LiDAR Data

Abstract

This paper proposes a new method for the automatic generation of a digital terrain model (DTM) from airborne laser scanning technique. First, generate regular grids, and then filter the points on each regular grid. Finally, change the size of grid and filter these points on the new grids repeatedly. The data measured by LiteMapper-5600 in a city is used to evaluate the method. The results show that this method can remove most of non-ground points effectively and generate DTM with the high-accuracy in urban areas.
