2021 Virtual Training Weeks 3 - Afternoon session with 3 presentations - check the description for more info Description:
14:00 Volume Computation
TerraModeler has tools for quantity computation. Those can be utilized to calculate and report the volume between two surfaces and/or based on tunnel or trench sections.
Demo shows the volume calculation of stockpiles.

15:00 Sight Distance Calculation
Using mobile data to analyze line of sight on a road. How to compute driver sight distance forward along the road at regular interval and how to compute sign visibility at regular interval along the road.

16:00 Ground Classification of UAV-based Photogrammetric Point Clouds
Determining the ground level from photogrammetric UAV point cloud data is ambiguous and conventional ground classification approaches that rely only on the geometric information will struggle with the task as they tend overestimate ground level on the top of short vegetation. To overcome this challenge, Terrasolid has developed a new method that includes vegetation index information in computing the distance attribute.
The vegetation index distinguishes vegetation hits from the ground points in photogrammetric point clouds even when the real ground level is covered with vegetation. The new processing strategy implemented in TerraScan overcomes limitations of classical ground classification algorithms and provides a new solution to process UAV-based photogrammetric point clouds.

2021 Virtual Training Weeks 3 - Matching photogrammetric point cloud to georeferenced LiDAR point cloud - 31.3. Morning Description:
The use of photogrammetric point clouds is rapidly increasing due to increased drone activities. One can improve the georeferencing of such point clouds by matching to an overlapping LiDAR point cloud with verified accuracy.
This presentation will give you an introduction to TerraScan tools that can be used for such matching procedure which can improve the geometric quality of photogrammetric point cloud considerably.
