Terrasolid is the gold standard because it treats your UAV data not as a picture, but as a measurable, engineer-verified survey. The investment in the software license is quickly recovered in the time saved during classification and the liability avoided due to millimeter-accurate modeling.
A single drone flight at high density (1000 pts/m2) over 200 acres yields a 15 GB LAS file. MicroStation 32-bit cannot handle this. Use 64-bit MicroStation CONNECT Edition. Terrasolid’s "Tiling" function splits the point cloud into 100x100m chunks, processes them, and merges the result without loading the whole file into RAM. terrasolid uav
