Airborne strip adjustment with TerraMatch

Airborne laser scanning, including drone applications, produces several overlapping flightlines. To verify the geometric quality of the data sets TerraMatch offers a series of tools. Observations, corrections and adjustments can be analysed statistically and visually produce a reliable point cloud which can be used for further processing. This presentation introduces tools in TerraMatch that can improve the quality of your LiDAR point cloud considerably.

Point cloud and vector data export to Google Maps with TerraScan and TerraPhoto

Workflow demonstrations on how to:

  • Use TerraScan to share Point Cloud Data using Google Maps
  • Export views of point cloud and vector data with TerraPhoto to be used in Google Maps. The rendered image frames can store location tag in their EXIF-metadata, and any external program supporting this can be used for visualization.

High Quality Large Area Orthophoto production

Visualize laser and image data together in TerraPhoto and produce high quality orthomosaics.

High Quality Orthophotos require a correct ground model, improvement of positioning of the raw images, color corrections and seamlines, and possibly 3D vector models of objects on the surface. Produced orthos can be used to colorize the point cloud.

Orthophoto generation from mobile images

This presentation shows a workflow to produce road orthophoto from mobile images and Mobile Laser Scanning (MLS) data. Orthophos are a great complement of LiDAR data in MLS data capture projects giving better idea of the road condition. Georeferenced orthophotos can be also used in many CAD and GIS systems.

Matching photogrammetric point cloud to georeferenced LiDAR point cloud

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.

Ground classification of UAV-based Photogrammetric Point Clouds – Interarial Stage presentation

UAVs are promising platforms for capturing spatial information. They are an affordable solution, which are easy to bring to the surveying field and can operate automatically. Usually these devices are equipped with optical sensors whose data provides 3D information of the field in form of colored point cloud. However, determining the ground level from this 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.
