Airborne LIDAR has a large number of data, which contains a large amount of redundant information. The information have little help or no help on the follow-up analysis, but the redundant data will take up a lot of storage space and computing time, which will take the inconvenience to the LIDAR data transmission and application. Therefore, in this paper we provide a kind of block algorithm on the basis of tile pyramid, which could rapidly process LIDAR data and reduce the data volume in the terrain mapping. Then based on the block algorithm, we put forward the simplification of LIDAR data, the experiment results show that the algorithm can control simplification degree of point cloud, delete the maximum redundant information, adaptive to retain topographical features information. Therefore, we could construct the Multi-Level of Detail Organization of Airborne LIDAR Data, and it can be the basis of the visualization and transmission network of LIDAR data.
