Topic:
What is the Working datum reference toggle in the Load well info window used for?

Description:
There is a new toggle in the Load well info window selected from Utilities in
the IESX Data Manager. The Working datum reference can be toggled to IESX 10
Method or Geoframe Method when loading borehole information.

Solution:
In IESX 10.x the elevation used as a reference was the working datum plus the
permanent datum. In GeoFrame 3.x the permanent datum is not used; all datums are
referenced from the working datum. If a borehole file has both a permanent and
working datum there will be a difference between the datum shift in an IESX 10
project and a GeoFrame 3.x project. When the IESX 10 Method is selected for
loading, the permanent datum and working datum are added together to make a new
working datum. When the GeoFrame Method is chosen, the working datum is kept
unchanged and the permanent datum is loaded but not used.
