Only when running TerraScan macros on a project in TerraScan or through GeoCue’s LIDAR 1 CuePac can an overedge region be specified. The macro loads points from neighbor tiles to: support the algorithms maintain continuity between data files, such as providing for a continuous surface at the block edge Should be done when doing routines…
The LAS specification requires that the File Source IDs and the Point Source IDs match (i.e. are the same number) when the LAS file contains data from a single flight line, drive pass, or strip of data. To ensure that this requirement is met, we can use a combination of TerraScan and GeoCue processes. Step…

Detailed Description: System.NullReferenceException: Object not set to an instance of an object. …” Solution: Errant tasks such as this can be deleted from the system through the use of the…
GeoCue has the ability to import source LIDAR strips with multiple scanners and assign the scanner number to the User Byte in the LAS format. The User Byte is what TerraScan uses for the scanner since no scanner attribute existed before LAS v1.4, and the field, even in LAS v1.4 is limited to a small…
When working with data in county coordinate systems, the definitions of datum transformations are important. The steps in this CueTip provide recommendations and an example of such a project; beginning from project setup, to selecting appropriate Coordinate Reference Systems (CRSs), to properly defining the coordinate transformations. Please consult with your surveyor to determine the appropriate…
Problem: While attempting to populate LAS Working Segments the process errors with an exception. In the system message column of the Checklist Step History you note the following exception: System.ArgumentException: Source array was not long enough. Check srcIndex and length, and the array’s lower bounds. at System.Array.Copy(Array sourceArray, Int32 sourceIndex, Array destinationArray, Int32 destinationIndex, Int32…
In the GeoCue Command Dispatch System (CDS) the Processing Priority (or simply priority) determines the processing order of subtasks that could otherwise process in any order. Priority in the CDS is a floating point number ranging from 0.0 to MAX_FLOAT. Higher values are considered higher priority. For example, assume that two LIDAR Orthos are in the…
The Set Attribute Checklist step can be used to allow a user of the GeoCue Client to manually set or modify attributes that are associated with the checklist’s entity or entities if more than one are launched from the Working Set at the same time. This is quite handy for providing necessary additional parameters when…
Problem: Attempting to Run Macro in GeoCue results in a “RunMacro Exception: System.Exception: Unable to ReadFileNumber after 1000 attempts” error message in the System Messages of the Checklist Step history. Probable Resolution #1: Verify that the GeoCue temp folder has been set by opening Configure Client. Also, verify that the path in “GeoCue Temp Folder”…
