Error 6: EPSG PCS/GCS code not found in EPSG Support Files

Symptom:

While running the Point Cloud Statistics Extractor Point Cloud Task it returns "Error 6: EPSG PCS/GCS code 37518 not found in EPSG Support Files. Is this a valid EPSG coordinate system?". The error message indicates that one or more input LAS files has been assigned an EPSG code that is not a valid code.

Probable Resolution:

1. Use LDDump or the Add Files dialog in LP360 to review the coordinate system information associated with your input LAS data.
2. Verify that the code, for example, 37518 is a valid EPSG code.
   1. Spatialreference.org is a good reference and is easy to use and access
   2. EPSG is the definitive organization, but a bit harder to review the information.
3. If desired, fix the assigned code to an appropriate EPSG code by using the LAS File Analyst in v2018.1 and later, or the Export Wizard.
4. If the code is valid, update the EPSG support files by following the instructions here.
