The aim of the filter processing to LIDAR dataset is to divide the dataset into ground points and non-ground points. So, the filtering of LIDAR dataset is a crucial step to obtain the DEM with high precision. Over the last few years, some algorithms have been developed to filter LIDAR data. This paper studies three filtering algorithms that are used in common at present, brings about some improvement to the MLS filtering algorithm which is one of the three filtering algorithms and gives two datasets as experimental data in order to compare and analyze the filtering results.
