How to remove point data that doesn’t have any corresponding trajectory information?

The best workflow to use to remove the point data for which you do not have trajectories is to: Modify line numbering to set all points to have the same line number, say 999. Deduce using time to assign flight line numbers from the trajectories to the points. Delete those points that remain in line…

Threading in TerraScan, TerraMatch and TerraPhoto

Most customers run a processor with four cores, high quality models today have eight cores . Each core supports a maximum of two threads. TerraScan (TerraSlave ) currently supports a maximum of 128 threads. To benefit from all threads you should have a PC with eight processors with eight cores. If you are a standard…

TerraModeler: Automating Volumetric Reporting

When producing volume reports, TerraModeler, as with all Terrasolid software follows a convention of producing ASCII reports. These reports can then be easily integrated into formats desired to produce respectable deliverable reports. In the case of volume reporting, TerraModeler supports a nice and easy reporting method using an external application that replaces multiple values in…

Smoothen Points – XYZ Option

Smoothen points is a command that smoothes the attributes of points relative to adjacent points. Until recently, the modifiable point attributes were elevation, intensity, or color. The elevation option could be used to iteratively adjust elevation values of points using plane-of-best-fit equations to result in a smoother surface. The intensity option could be used to…

Classify Surface Points Routine

Photogrammetric point clouds are notoriously noisy, very dense, and generally lack points located underneath vegetation. Echo information is non-existent and surface roughness are not as useful for ground classification with these point clouds. Point clouds from low quality LIDAR sensors exhibit some similar characteristics. Hence, a different approach is needed In general, it is a…

Hiding and Showing Applications in License Manager

The Terrasolid allows for the customization of the list of applications in Terra License Manager. This allows the user to hide unnecessary applications (Applications that the user does not have) from the list to streamline the license checkout process for client machines. Simply select the the unnecessary application(s) in the list and select the ‘Hide…

Photogrammetric Point Cloud Processing

Point Clouds generated through photogrammetric methods (such as Dense Image Mapping) have different characteristics than traditional airborne laser scanner systems or “normal” LIDAR point clouds.  Specifically, the data is very dense, which can negativity impact processing time, and the data is also very noisy, which can cause the normal classification routines to err. The echo…
