The aim of the filtering of LIDAR data set is to divide the data set into ground points and non-ground points. The filtering of LIDAR data set is a crucial step to obtain the DEM with high precision. This paper detailedly studies several filtering methods that are used in common at present, brings about some improvement to the MLS filtering method and compares the filtering results.
