Date: October 26, 2023 Subject: A Technical Analysis of Processing Aerial Data using the Terrasolid Software Suite

Terrasolid is not intuitive. It was built for engineers in the 1990s, and the interface reflects that. Solution: Invest in the official Terrasolid Training (TST) courses. Focus specifically on the "UAV Quick Start" manual. Learn keyboard shortcuts—TerraScan is virtually unusable without them. terrasolid uav

For UAVs without LiDAR (DJI Phantom 4 RTK, Mavic 3E): Date: October 26, 2023 Subject: A Technical Analysis

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.
