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.

Terrasolid is widely regarded as the premier software for corridor mapping.
