Terrasolid applications provide versatile and capable tools for surveyors, civil engineers, designers, planners, and anyone who needs to process and utlize 3D LiDAR data. Terrasolid applications are built on top of Bentley software which is required before installation. Full and light versions of each application are available and can be combined in packages tailored for your specific working requirements.
Terrasolid is a highly flexible and compatible software designed to manage any application involving LiDAR data in addition to applications also involving imagery. The software products are neither fixed to certain applications nor to specific laser scanning or camera systems. The software can deal with data from airborne and mobile systems and even data from static terrestrial scanners can be processed to a limited extend. Terrasolid offers a range of software to cover the whole production cycle from calibrating and matching raw data to the creation of final 3D vector models, ortho photos and terrain representations.
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 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
3D vector data creation
Processing vast amounts of laser point data and images can be a real challenge to a single PC. With TerraSlave you can distribute time- and resource-consuming tasks such as TerraScan macro execution to several PCs over a LAN and thus, free your own workstation for other processing steps. TerraSlave comes as stand-alone application with an easy-to-use graphical interface for managing tasks. Additional functionality includes the queuing of several tasks as well as a simple reporting system based on text files.
There are basically two options for a TerraSlave setup in a LAN: 1) TerraSlave may be installed on workstations and active users can use any free workstation for TerraSlave processing. 2) TerraSlave and all data may be located on a fast server for performing the time-consuming tasks. Since TerraSlave is a stand-alone application, these “slave” PCs and servers do not need to have MicroStation or any other Terra Software installed.
Even on a single PC you can profit from using TerraSlave. It processes TerraScan macros outside MicroStation, and thus, you are able to continue working with TerraScan without the need to wait until the macro execution has finished. TerraSlave is automatically installed with TerraScan on a single PC and a TerraSlave license is provided with each bought TerraScan license.
