September 10, 2024
RST Ltd. uses UAV-mounted LiDAR (UAV LiDAR) to provide high-density point-cloud scanning that effectively penetrates vegetation to obtain true ground elevation, producing digital terrain models (DTM/DSM) that support surveying and change analysis for farm roads, landslide areas, and major engineering sites.
Service Capabilities
- Vegetation-penetrating scanning: Multiple LiDAR returns capture the true ground surface beneath vegetation, producing a high-precision DTM.
- High-density point-cloud modeling: Terrain point clouds, contour lines, and digital elevation outputs are produced.
- Multi-period change analysis: Scan results from different periods are compared to identify changes in terrain and sediment.
- Integration with surveying: Results can be combined with aerial photogrammetry and ground control surveys to improve accuracy.
