Terrasolid - Phoenix LiDAR Systems

In addition to Phoenix LiDAR Systems comprehensive SpatialExplorer Pro post processing software, we proudly offer TerraSolid products to customers with additional application specific needs. The Terrasolid software suite provides versatile and capable tools to create 3D vector models, feature extractions, batch processing, terrain representations, advanced point cloud visualizations, etc., no matter the data source, no matter the sensor.

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 number 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.

TerraScan is available in Full, UAV and Lite versions

Go even further with TerraScan

Automatic classification routines can be combined in macros for batch processing. Using TerraBatch macros can be executed outside TerraScan even on other workstations over a LAN. License to run TerraBatch on the same computer than TerraScan is included giving you the ability to utilize your computer 24×7.

TerraScan supports several import and export formats, including the LAS and LAZ formats, TerraScan Binary formats, as well as user defined ASCII formats.

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 multiple 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.

TerraModeler is available in Full, UAV and Lite versions

TerraModeler can use many different surface sources

Creation of surface models from several sources, e.g. laser points, breakline elements, xyz text files delivering the best possible results for the analysis or end product.

Contour line production

Contours are the traditional and familiar way of depicting elevation differences on a map. LiDAR produces a point cloud that represents the ground and objects on it. Points classified with TerraScan can be used as basis for contour line creation in TerraModeler. Terrasolid software distinguishes two types of contour lines. There are mathematical contour lines which follow the elevations of the laser points very accurately but are not very useful for mapping purposes and cartographic contour lines which are smooth and nice-looking but less accurate.

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.

TerraPhoto is available in Full, UAV and Lite versions

Ortho-rectification of Images and Data Visualization

Besides starting a camera calibration from scratch, TerraPhoto is able to convert calibration files from several mobile and airborne systems into its own camera file format. It reads numerous image formats, such as ECW, GeoTIFF, TIF, BMP, CIT, COT, RLE, PIC, PCX, GIF, JPG2000 and PMG.

Combine TerraPhoto with other Terra applications

TerraPhoto offers many tools for visualizing laser and image data together, partly in combination with tools from TerraScan and TerraModeler. This includes the opportunity of draping ortho photos on a ground model or on building roofs, the creation of wall textures from horizontally-looking cameras of mobile or airborne systems, as well as the display of rendered views. With TerraPhoto you can also create fly-through animations from laser and image data in an easy and intuitive way. Finally, the extraction of color values from images or ortho photos to laser points can be performed with TerraPhoto and TerraScan.

TerraBatch

Processing massive amounts of laser points and images can be a real challenge to a single PC. With TerraBatch 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 TerraBatch 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.
