We are pleased to announce that the latest issue of Sensors features an article combining testing of various LiDAR sensors with analyses of erosion relief in loess areas, authored by three members of the Department of Geology, Soil Science and Geoinformation UMCS: Dr. Piotr Bartminski, Dr. Marcin Siłuch and Prof. Dr hab. Waldemar Kociuba:
Piotr Bartmiński, Marcin Siłuch, Waldemar Kociuba, 2023. The Effectiveness of a UAV-Based LiDAR Survey to Develop Digital Terrain Models and Topographic Texture Analyses. Sensors 23, no. 14: 6415. https://doi.org/10.3390/s23146415
A comparison was carried out between data acquired from three LiDAR sensors from different manufacturers, i.e. Yellow Scan Mapper, AlphaAir 450 Airborne LiDAR System CHC Navigation and DJI Zenmuse L1. The sensors were mounted on a DIJ Matrice 300 RTK UAV platform. The test area was a ravine system with developed vegetation. Reference data from the ISOK project was used for comparison. Large discrepancies were shown between the different systems, exceeding the values quoted by the manufacturers. The maximum differences for the YSM scanner were 3.80 m, for CHC 6.62 m and for L1 16.8 m. The high differences were mainly due to misclassification of point clouds. It was concluded that reference data, acquired by traditional techniques, should be used to ensure the quality of the final product. Future research should extend the range of sensors used; further comparative studies of different market solutions are advisable.
