Tutorial: Sight Distance along Corridors using TerraScan

Sight distance assessment is of major importance for road safety. It is essential that available distances along roads are sufficient for emergency stops or overtaking maneuvers where required. Sight distance of signage can be used to assess safety when it comes to traffic signs or rail signals, or show the economics of a billboard. The…

Tutorial: Add Known XYZ Tie Points in TerraPhoto

The absolute accuracy of the images can be verified and possibly improved with the help of ground control points (GCPs). GCPs can be placed in TerraPhoto as Known XYZ tie points. They must be entered manually in images that see the GCPs’ locations. Known XYZ tie points are entered based on points for which the…

Tutorial: Colorizing Airborne data from Orthomosaic

Simple way of colorizing an airborne point cloud data by using an attached orthomosaic. The Extract Color from Images command extracts color values from raster images and assigns the values to laser points. The color sources can be orthophotos attached as TerraPhoto raster references or raw images in an active TerraPhoto image list.

Tutorial: Extracting Color to Point Cloud from Ortho Images

Tutorial will use TerraScan, in combination with TerraPhoto, to extract RGB values from an orthophoto in order to assign a color value to each LIDAR point. This enables the information to then be used in classification routines and visualization. Data from Finnish National Land Survey 5p samples
