Application of LIDAR in Forest Resources Survey

Apr 18, 2023

With the development of LiDAR, the investigation and management of forestry resources has become more modern. Feiyan Remote Sensing has completed the forest resources survey of 9 counties with different representations in Anhui Province through two sets of LiDAR equipment, and won the second prize of Anhui Province Surveying and Mapping Geographic Information Technology, and handed over a new answer sheet to promote forest resource management .

The project uses the self-developed software P3C to accurately classify vegetation and ground point cloud data. The classification accuracy of vegetation points in densely-vegetated areas is ≥98%, the classification accuracy of vegetation points in sparsely-vegetated areas is ≥95%, and the classification accuracy of vegetation points in urban areas is ≥80%.

The successful completion of this project proves that the accuracy of the airborne LiDAR can not only quickly realize the annual update of the forest resource survey, but also eliminate the need for personnel to carry out heavy and dangerous field collection work, which liberates human resources and improves production efficiency.
