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..
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..
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..
