3D scanning & LiDAR
Terrain Under Forest — Drone LiDAR Survey
- Year
- 2026
- Location
- Northern Bulgaria
- Our role
- Airborne laser scanning with a LiDAR drone, orthophoto, terrain model under the canopy and tree cover analysis.
- 15.9 ha — dense broadleaf forest, park, buildings and meadows, surveyed in September in full leaf.
- RIEGL miniVUX-3UAV LiDAR on a DJI Matrice 400 drone — 13 strips, about 14 minutes of scanning, 39.2 million points (247 points/m²).
- Terrain under the canopy — under trees taller than 5 m the laser reached the ground with 34 points/m² on average.
- Georeferencing to 9 ground control points.
- Terrain model (DTM) with 1 m contours and profiles through the forest.
- Tree cover — canopy height model, 800 automatically detected trees over 5 m, median 12.5 m, the tallest about 38 m.
Deliverables: classified point cloud, DTM and DSM, contours, profiles, orthophoto and tree data.
