[GF] Strange Survey Origin

[Brian Stevens]

Thanks for the responses I received.  I found this morning that at least one other project (probably a "clone" of the first) is exhibiting the same behavior.  I'll try to find a one of the projects not actively in use and see if I can fix it.  I'll report back with what does (or does not) work.

The survey's inlines and xlines both start at negative values, and the area of the survey appears much larger than it should be.  Examining the survey origin/locations in the data manager, it has these three points:
