Errors in Terrasolid – Showing up in Red

Errors with Trajectories, Macro Steps or Images within the Terrasolid software will show up in red. Within TerraPhoto a Red Dash in the File Status Field indicates that TerraPhoto cannot find the image. Check the image path location in the Mission to verify that it is pointing to the location of the images. An error…

Hard Surface Classification

The Hard Surface Routine is based off a planar fit algorithm, which is quite different than the traditional ground classification algorithm traditionally used for airborne LIDAR data. The hard surface routine will classify the dominant, median surface points. This provides an alternative to the traditional ground classification routine. The result is usually better performance on paved…

Fixing LAS timestamps

In some cases hardware manufacturers and/or software are not properly setting the GPS Timestamps in an LAS file according to the LAS specification. That specification dictates that the timestamp for LIDAR points be stored in either weekseconds or Adjusted GPS Standard time. This is very important as the tools within TerraScan and other software expects the…

Scale Intensity in TerraScan

When working with LIDAR data there is no standard for normalizing intensity return values. Hence, there are times when the intensities within LIDAR data do not match between different scanners, or even different altitudes. This disparity can lead to issues when trying to use the LIDAR data intensities to extract features or during calibration. TerraScan…
