Footprint polygons can be used in building vectorization process. This short tutorial explains the importance of the footprint quality and demonstrates the Check Building Footprint Polygons and other tools in TerraScan to improve it. The same tools can be used to check the building information quality of topographic maps. List of tools used in this…
A short tutorial showing how to use Vegetation Index or Echo Length in TerraScan to enhance the ground classification. List of tools used in this presentation: Read Points – Load points into TerraScan Display Mode – View points by Color or Echo length coloring Compute Distance by Vegetation Index or Echo Length – Translates values into distance values as a probability Display Mode…
With TerraModeler you can create, edit, and utilize surface models, such as a digital terrain model. TerraModeler creates surface models (TIN, DTM, DSM, etc…) and visualizations from various sources, such as LIDAR points stored in binary files or loaded in TerraScan, XYZ ASCII files and/or graphical design elements. List of tools used in this presentation:…
This short tutorial is an introduction to 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 passes and calculates correction values for the misalignment angles as well as xyz location errors.
This short tutorial is an introduction to 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…
The user receives multiple error messages and has general functionality issues when opening an ArcMap project with the 32 bit LP360 extension enabled. Example error message could be: PCTasksContentsView::ConnectToTrans(): Map object is null. This issue is related to the user opening an existing project, that was saved with the point cloud tasks tab open. The…
Civil3D has known import DEM issues. The user may notice a systematic shift related to units or grid positioning mismatch when comparing the imported DEM to other data in Civil3D, such as the breaklines that were also generated in LP360/True View EVO as part of the . Note: Depending on the scenario, the user may…
A short tutorial showing how to use the Agisoft Metashape Confidence Value as a reliability attribute for ground classification in dense image matching photogrammetric point cloud classification. Dataset courtesy of ELY-Keskus – owner and Mitta Oy – creator. List of tools used in this presentation: Read Points – Reliability attribute is selected at import. Display…
