Abstract

There are many method for DEM generation such as: collect the surveying data, aerial photgrammetry and satellite image processing. Recently LiDAR is a new method which is experimenting in Vietnam and it improved its prominent capabilities. LiDAR is a active remote sense system which uses laser ray to measure the distance between the sensor and the object on the earth (houses, trees…). This system can also create the height points cloud with good accuracy. This paper focus on the abilities of LiDAR and its processing for DEM generation of Bac Giang province.
