Symptom: Attempting to checkout a floating license results in an error message stating, “RLM Error: Failed to get License as there are no licenses available”. Probable Resolution #1: Verify that there are license types available in the “Available Licenses” dropdown. If there are, then check the Licenses tab to see if there are any available…
Airgon generally recommends using a shutter interval (amount of time the shutter is open) of 1/800th second for typical drone mapping flight plans. However, as flight speed increases and/or GSD decreases, a faster shutter speed (shorter shutter interval) may be required to prevent motion blur. The proper shutter interval for a situation can…
With the release of LP360 v2017.1 we began recommending that users create their breaklines using LP360 instead of the previous recommendation of using the LP360 Sketch tool in LP360 for ArcGIS. One common question that has come up is how does one create a flat 2D feature and put the summarize Z results in the…
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…
Problem: The following error may be encountered while attempting to terminate a task in the Dispatch Manager: “An error occurred terminating the selected tasks. 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…
A Pennsylvania State University Student Project by Travis Meyer Introduction Mangroves fulfill an important niche in wetland ecology and play a significant role in modifying the global carbon budget. They harbor and provide shelter for the offspring of many species of water birds, fish, and reptiles, and sequester close to five times the amount…
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: An LP360 crash can occur when attempting to read in a lot of files. This can occur when opening the ‘Add Files’ dialog and browsing to the files’ location to add them into the session. Due to the way that browsing control works, this can get overwhelmed with a large number of files, causing…
Buffer classifications (or Ignored Ground in the USGS Lidar Base Specification) are those classes that are assigned to LAS points that are within a user defined-distance of breaklines. Points that are assigned to these classes are excluded from the surface when using breakline enforcement. Typical distances used are one quarter to one half the nominal…
