GeoCue 3DIS scanner systems list for Terrasolid: TerraMatch

The GeoCue 3DIS systems have specific system number and lever arm values associated with each type of LIDAR sensor, which are used in Terrasolid – TerraMatch software for boresight and flight line corrections. These are written into Terrasolid format trajectory files, that can be used directly in TerraScan. This article will review these values and…

Update LAS file pyramids

Under normal circumstances, LAS files only need have pyramids generated during initial import into LP360/True View Evo. However, there are times when the user must rebuild LAS file pyramids after performing specific LP360 tasks. This article will review the method used to update pyramids, as well as the known tasks which will precipitate the user…

Using a point grid based on a vertical feature for change detection

It may be desired to create a grid of points for a vertical feature, such as a wall in LP360 or True View Evo. This could be used to detect the change of a set of gridded points, that are static in Z, which could potentially shift planimetrically over time. The following outlined workflow will…

Archiving True View Cycles to Reckon

GeoCue customers using True View products can upload their cycle data using our cloud service Reckon. Each customer account has a Reckon account with an account administrator that was e-mailed credentials when the first product is purchased. The administrator can add users and control user permissions giving them permission to publish or process data. Archiving…

Recommended LAS file size

While LP360 can handle a practically unlimited amount of LIDAR data, individual LAS file sizes must be kept small. LP360 and True View Evo have a maximum recommended individual LAS file size to optimize performance and functionality of the software. If the size of any LAS file used exceeds a recommended size of 250 MB,…

Metashape: No Completion E-mail from Create Ortho from Photo Package

In True View EVO, when running the Create Ortho from Photo Package tool you receive no completion e-mail notification and notice the background Metashape process exited. Review the processing log located in the folder under the Photo Package corresponding to the run attempt (PhotoPackageName\Metashape\PhotoPackageName_YYMMDDThhmmss\PhotoPackageName_YYMMDDThhmmss_log.txt). It would typically include three steps between the processing started and…

Executing task(s) failed (8690)

Receive an error message, “Executing task(s) failed (8690)” while trying to execute a Point Cloud Task. This is a catch all error message that generally occurs when something caused the PCT to fail in its execution. Verify the parameters for the desired point cloud task correspond with the loaded data and desired execution method. Description:…

Affine Transform LAS PCT

The Affine Transform LAS Point Cloud Task is a versatile tool for modifying the coordinates of your point cloud. A common use is applying grid to ground conversions which require more than a simple scale or translation. How to setup the Affine Transform LAS Point Cloud Task to accomplish this may not be readily apparent…

Derive Grid to Ground Transformation with TerraScan

For certain projects, it may be necessary to process and output derivative products in a user defined (local) coordinate system. There are multiple ways to accomplish this, but one is to have matching pairs of projected and local coordinates to define a local coordinate system and derive the transformation. If the rotation, scale and translation…
