TerraScan is the main tool in the Terrasolid suite for managing and processing LiDAR data. It enables importing, structuring, and automatic classification of large point cloud datasets, including trajectory information from scanning campaigns. In addition to processing, TerraScan provides tools for automatic generation of 3D vector models (e.g., buildings, power lines, roads). Analyses include detection of hazardous objects, road surface condition, and pavement markings. The software supports batch processing through macros, network execution, and various formats (LAS, LAZ, binary, ASCII).
