A Database Approach to Very Large LIDAR Data Management
LiDAR data Octree Quadtree Local KD tree Display precision
2015/11/20
This paper presents an approach to realizing LiDAR data management in DBMS. We use octree to partition data space, and build a local KD tree at each octree’s node. In data organization, we take precis...
