Problem:
Attempting to populate LAS Working Segments in GeoCue results in an exception message in the system message column of the checklist step details pane for the Populate step stating, “System.OutOfMemoryException: Array dimensions exceeded supported range.

Probable Resolution #1:
GeoCue 2017 and earlier are only capable of writing LAS Working Segments smaller than 2GB in size. Reduce the dimensions of the affected working segments by splitting or gridding them in a manner that the populated LAS file size will be less than 2GB.
