In this study, a multilevel change detection method is proposed for buildings using airborne laser scanning point cloud data and GIS vector data. To detect detailed information of each changed building, the roof points and corresponding roof segments in laser scanning data are obtained by a multi-entity based classification method and a connected component(More)
Data filtering and image segmentation are two crucial steps in individual tree information extraction based on airborne LiDAR data. In this paper, a new image segmentation method was proposed to isolate individual tree and extract tree height and size information of the tree crowns, which is the fusion of marker-controlled watershed segmentation and(More)
