Terrasolid
The industry standard software for point cloud and image processing
PCI Software Pvt. Ltd. is the authorized reseller for Terrasolid software in India and SAARC Countries. To purchase Terrasolid products please contact the PCI Sales Team.
Terrasolid is the industry standard software for point clouds and images processing, developed specifically for the demanding requirements of geospatial, engineering, operations and environmental professionals.
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, UAV, mobile and static scanners.
Terrasolid software suite provides versatile and capable tools to create 3D vector models, feature extractions, orthophotos, terrain representations, advanced point cloud visualizations, etc., no matter the data source, no matter the sensor. The finest tools for calibration and matching of point clouds for LiDAR data are included.
Terrasolid products
The Terrasolid product family consists of six main products – TerraScan, TerraModeler, TerraPhoto, TerraMatch, TerraStereo and TerraSlave which can all be combined into unique solutions to cater your particular needs of point cloud processing. Most of the applications are built on top of Bentley Systems’ software. The Terrasolid products are also available running on Spatix platform.
TerraScan
TerraScan is the main application in the Terrasolid Software family for managing and processing all types of point clouds. It offers import and project structuring tools for handling the massive 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.
Point cloud management, processing and visualization is only one part of TerraScan. In addition, the software provides automated tools for creating 3D vector data based on the laser points. Users can produce 3D vector models of buildings (up to LOD2) automatically over nationwide areas, vectorize power lines, run corridor analysis reporting danger objects or analyze road surface condition or detect paint lines and curb stones. The results from the fully 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 batch processing 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 and LAZ formats, TerraScan Binary and TerraScan Fast Binary formats, as well as ASCII formats that can be defined according to the users’ needs.
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.
TerraMatch
TerraMatch is a sophisticated tool for improving the accuracy and quality of the raw laser point cloud. It compares laser data from overlapping flight or drive paths and calculates correction values for the misalignment angles as well as xyz location errors. The comparison and correction value calculation can be either based on surface matching or on different types of tie lines. Tie line matching comprises points or lines on horizontal, vertical or sloped surfaces that can be used for matching flight/drive paths to each other, but also known point or line locations that enable the adjustment of the laser point cloud to control measurements.
TerraPhoto
TerraPhoto is specifically developed for processing images captured together with laser data during a survey mission. The software enables the production of rectified images and ortho mosaics based on ground model that has been extracted from the laser data. The positioning of the source images can be refined by using tie points for image-to-image adjustment while ground control point can be involved for improving the absolute accuracy of the image block. With additional functionality, such as color adjustment options, the creation of selection shapes for several object types or areas (e.g. buildings, water), the inclusion of vector models for true-ortho photo production, TerraPhoto lets you create ortho photos of good positional and color-coordinated quality.
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 screen captures
- Combine different visualization channels 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
- 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
TerraSlave
Processing massive amounts of laser points 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.
Right to run TerraSlave on the same computer than TerraScan is included into TerraScan license giving you the ability to utilize the power of your computer 24×7. Additional licenses can be purchased separately.
More capacity through distributed batch processing
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.
Setup options for TerraSlave
There are 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 processing PCs and servers do not need to have MicroStation or any other Terra Software installed.
