Terrasolid UAV is a specialized software suite designed for the processing, analysis, and management of LiDAR and image-based point cloud data collected by unmanned aerial vehicles (UAVs / drones). Built on the robust Terrasolid platform — natively integrated with Bentley Systems’ MicroStation and CAD platforms — Terrasolid UAV bridges the gap between raw drone data and actionable geospatial intelligence.
The suite is widely used by surveying, engineering, forestry, mining, and environmental monitoring professionals who demand high-precision, scalable workflows from flight to final deliverables.
To understand the value of Terrasolid UAV, one must walk through the typical project workflow.
TerraSolid’s "Profile View" is legendary. You can slice the point cloud along any line to verify that the ground classification did not mistake a truck for a rock. For UAV surveys intended for engineering design (1-foot contours), this manual QC step ensures sub-5cm accuracy.
Multispectral UAVs can't see the forest floor. Terrasolid can.
After flying a DJI Matrice 600 with a LiDAR (e.g., Riegl miniVUX or Hesai) or a DJI L1/L2, you have a .las or .laz file and a trajectory file (SBET). In TerraScan, you import these assets. The unique "Strip Adjustment" tool fits multiple flight lines together, correcting the "bow-tie" effect common in UAV lidar.
Mines move daily. A weekly drone flight produces a point cloud. In TerraSlava, the user defines a "baseline surface" (the original ground) and a "current surface" (today’s drone scan). Within seconds, Terrasolid calculates stockpile volumes to within 1-3% accuracy—critical for royalty payments and inventory.
1. Import raw .las into TerraScan (Project > Import Points).
2. Clean data: `Classify Outlier` (low/high noise).
3. `Classify Ground` (use key settings: Angle = 88°, Distance = 1.5m).
4. `Classify By Height` to separate low veg (0.5-2m) from high veg (>2m).
5. Switch to TerraModeler: `Create Triangulation` from ground class.
6. `Draw Contours` (intervals: 0.5m for UAV survey).
7. Export: DTM as GeoTIFF, contours as DGN/Shapefile.
Quarries and stockpiles change weekly.
