The derivative products and applications of point cloud data are based on point cloud classification.
Based on the fact that airborne lidar can't get the reflection points in the water area, the algorithm detects the boundary of the hole points and automatically connects and closes them to form the water vector range line. Then submit the manual detection and correction to generate the vector distribution map of the water area.

Vegetation information is extracted from vertical spatial data of 3D laser point cloud for Ecological Statistics, analysis, management and decision support.
Aerial photogrammetry is generally low altitude flight, which is easy to operate in airspace and will not be affected by extreme weather. At the same time, it is not limited to the needs of take-off and landing sites. It only needs to select a relatively flat site for take-off and landin...
As we all know, aerial photogrammetry technology is playing an increasingly important role in urban planning and construction. Moreover, compared with the traditional topographic survey technology, aerial photogrammetry technology has the advantages of small volume, light weight, ra...
After the LiDAR data is obtained, the data can be post-processed only after data preprocessing. After the data preprocessing, there is a data checking software to conduct a preliminary check on the data results. The general data format check has the follo
