Allow Max Strip Numbers

  When importing raw swath data into GeoCue with flight line numbers that range over 32767, a message could appear requiring a number between 1 and 32767 to be used in the Assign Strip Numbers settings.   GeoCue is capable of numbering strips from 1 to 65535, but a change needs to be made in…

Loss of VLR information by TerraScan

With the release of TerraScan v017.001 for CE, TerraScan should now be preserving the projection VLR information in the LAS header. However, when processing with TerraScan, either directly or indirectly through GeoCue, there are some scenarios in which VLRs can be stripped from your data, or at least appear to be removed. Scenario 1: Reading…

Ground targets for horizontal check for LIDAR data collection

An important evaluation to make when performing a QAQC analysis of a LIDAR data set is a control point comparison. Typically, this refers to checking the vertical accuracy of a LIDAR data set. In regards to vertical check/control point location: “Unlike horizontal checkpoints, vertical checkpoints are not necessarily required to be clearly defined or readily…

GeoCue Adds Project Archiving in v2017 Release

One of the common requests we receive from our GeoCue users is to add the ability to archive or off-line projects when they are completed.  Once a project has been completed and fully delivered to the customer, it needs to be transferred effectively out of production operations to an enterprise data archive.  Archiving a completed…

Creating project blocks for a corridor

Building a Simple Corridor We will use an example of building a road corridor.  For this exercise, we have created a new project in the NAD 83, Zone 16 N meters horizontal coordinate system and ellipsoid, meters for the vertical system.  To this project we added a reference raster layer and imported the Madison County…

Enabling CONNECT in GeoCue 2014 SP5

Service pack 5 for GeoCue 2014 enables some capabilities to process your LASA v1.4 files from start to finish using TerraScan for CE. We leverage GeoCue’s ability to launch a TerraScan project for an external application and a registry edit to direct GeoCue to use the TerraSlave for CE. To facilitate use the links below…

Command Line Executable for Point Cloud Information

A quick and basic way to get information about projection information, GPS time and the number of points within an LAS file is to run the LDDump executable. The program is designed to pull the information directly from the public header block of the LAS file, provided the header has been correctly populated with the…

Hardware recommendations for faster processing

If you’re i/o bound, which is usually the case with LIDAR or photogrammetric point cloud processing, you need to figure out what kind of i/o you’re doing at the bottleneck. Case 1: If you’re just waiting for a single tile to load, your slowdown may be from low RPM HDD, but more likely you’re hitting…

UnauthorizedAccessException: Access to the path is denied

Windows 10 continues Microsoft’s trend to lock down security and permissions on computers as Microsoft attempts to thwart malware. In doing so, locations that were once accessible for programs and users alike are now off limits unless explicitly granted permission each time they are accessed. The “C:\Program Files\Common Files” is such a location, as is…
