TerraScan – Software for LiDAR Data Processing and 3D Vector Data Creation

>> Overview of functionality in TerraScan and TerraScan Lite

TerraScan is the main application in the Terrasolid Software family for managing and processing LiDAR point clouds. It offers import and project structuring tools for handling the large amount of points of a laser scanning campaign as well as the corresponding trajectory information. Various classification routines enable the automatic filtering of the point cloud. The results from the automatic classification can be refined by using half-automatic and manual classification tools in combination with versatile 3D point cloud visualization options.

Most of the automatic classification routines can be combined in macros for batch processing. In combination with TerraSlave macros can be executed outside TerraScan and MicroStation, even on other workstations over a LAN.

TerraScan supports several import and export formats, including the LAS format, TerraScan Binary and TerraScan Fast Binary formats, as well as ASCII formats that can be defined according to the users' needs.

Point cloud management, processing and visualization is only one part of TerraScan. In addition, the software provides tools for creating 3D vector data based on the laser points. There is also the opportunity to produce 3D vector models of buildings (up to LOD2) automatically over large areas. Toolsets for checking and modifying the building models manually enable the creation of more accurate and higher-quality building models. For the application field of power line processing, TerraScan contains tools for the automatic vectorization of power line wires, manual placement of tower models as well as labeling, reporting and danger object analysis tools.

TerraScan Lite

TerraScan Lite is a lighter version of TerraScan for viewing laser points that are already automatically classified and for performing processing steps that require manual effort. It replaced the previous TerraScan Viewer in 2012 when more functionality was added to the software.

The typical uses of TerraScan Lite are visualization of laser data, manual point classification, automatic classification of model or contour keypoints and model extraction, as well as manual check and modification of building vector models that have been created automatically with the TerraScan building vectorization tool. The functionality of TerraScan Lite includes:

  • loading and saving laser data in various formats
  • loading trajectories
  • setting up projects
  • manual classification tools
  • export options such as export lattice models or raster files
  • tools for drawing 3D vector data based on laser points
  • various commands for processing loaded points like transform points, cut overlap or color extraction from images in TerraPhoto (Lite)
  • adjusting laser points to geoid models
  • convert geoid models
  • set polygon elevations
  • read building vector models from text files generated with the TerraScan building vectorization macro function
