Improving Ground Classification with Vegetation Index using TerraScan

Enhance ground classification accuracy in point cloud by incorporating vegetation index using TerraScan. This video shows how to utilize vegetation index to distinguish vegetation hits from the ground points, especially in photogrammetric point clouds when the real ground level is not visible. Learn how to compute vegetation index distances, smooth the values, and apply them to the ground classification routine.
