TerraSolid

TerraSolid develops software products that are used world-wide for processing point cloud and image data from airborne and mobile LIDAR systems. Running inside Bentley’s MicroStation CAD software, TerraSolid offers a variety of tools for viewing, analyzing and extracting features from 3d point clouds accurately and efficiently. Additional modules offer workflows for LIDAR sensor calibration and point cloud data correction, surface modelling and orthophoto generation from LIDAR and imagery. TerraSolid software supports LIDAR data from all sources; airborne, mobile and static scanners.

 

TerraScan

Process raw airborne or terrestrial scanned laser data.

TerraScan is a versatile software package for processing raw airborne or terrestrial scanned laser data (LIDAR). Operators and other users read-in trajectories and raw data points and classify them into user-defined point classes like ground, vegetation and buildings.

Besides built–in formats, like LAS and TerraScan binary, the user can defi ne his own formats for reading-in practically any ASCII-survey files. All processing routines are optimised to reach the highest performance of the workstation. This performance will be easily exceeded, if the total data is hundreds or even billions of points. In such cases you can divide the data into smaller, geographical blocks by TerraScan and automate processing by user-defined macros.

Natural combinations to TerraScan in laser data processing are TerraSlave, TerraMatch, TerraModeler and TerraPhoto from Terrasolid.

TerraMatch

Correct laser data points optimized for MicroStation® SE/J and V8 from Bentley Systems.

TerraMatch is a sophisticated application for correcting laser data points optimized for MicroStation® SE/J and V8 from Bentley Systems. TerraMatch compares overlapping laser strips with each other and corrects orientation parameters to obtain the best fit and improved accuracy of the laser data. The adjustment is based on measured differences between the xyz shape or the intensity of laser points from different strips. The user can decide whether TerraMatch matches all the data points or only points from selected flight lines.

TerraPhoto

Produce orthorectified images from airborne images.

TerraPhoto produces orthorectified images from airborne images. It is specifically developed to process images, which are taken during a laser-scanning mission. TerraPhoto uses TIN of ground laser points for an accurate projection model. Some known points on the ground are used only for quality control. A seamless compatibility with the other Terrasolid’s applications for laser mapping and the complete orthorectification simultaneously with laser point processing does not let you pass TerraPhoto.

TerraSlave

Run TerraScan macros on a remote workstation.

We at GeoCue have worked with Terrasolid to integrate the TerraScan ‘slave’ processor directly into GeoCue. TerraSlave for GeoCue allows a remote workstation to run TerraScan macros submitted to it from the user’s local machine. It eliminates the need to have a MicroStation license on the remote machine, significantly reducing software costs. Removing the MicroStation limitation also allows you to use more memory, queue more tasks and in general makes optimizing your hardware easier. TerraSlave for GeoCue allows users to easily manage multiple batch processing jobs across your network. This saves considerable time, both in processing (by parallel processing to the limits of your available hardware resources) and error control (by providing robust error trapping of single subtasks, so entire batches are not corrupted by a single failure).

TerraModeler

With TerraModeler you can create, edit and utilize surface models. TerraModeler creates surface models (TINs) from various sources, such as LIDAR points stored in binary files or loaded in TerraScan, XYZ ascii files and graphical design elements. The software offers versatile visualization options including colored shaded surfaces, contour lines, grids, colored triangle nets, elevation texts, slope directions and textured surfaces (in combination with TerraPhoto). Additional functionality includes the production of contour lines and lattice models in batch processing, modification of the TIN, creation of profiles, calculation of volumes, calculation of elevation or volume differences between two surface models, several labeling options as well as other tools for design purposes. Completed with various export options, TerraModeler is a versatile tool for many kinds of design and modeling tasks.

TerraStereo

TerraStereo is a stand-along application for visualizing very large point clouds. It uses high-performance graphics boards for rendering huge amounts of points fastly and in high quality. The software enables you to:

  • visualize up to 50 billion points that are organized in a TerraScan project
  • perform visual analysis and quality check in both, small and large scale displays
  • navigate through the point cloud freely or based on TerraScan trajectory files
  • create animations
  • view laser data in stereo mode and create stereo screencaptures
  • easily change between different display channels and point rendering modes
    • elevation, intensity and class coloring
    • color by RGB values
    • shaded surface display
    • point density coloring
    • TerraZ rendering method for masking foreground objects
    • different quality levels for point rendering
  • combine different visualization channels in order to improve the perceptibility of objects in the point cloud
  • switch point classes on/off
  • apply elevation exaggeration to the point cloud for specific analysis tasks
  • measure distances within the point cloud
  • digitize line vector elements and export them to TerraSurvey
