To the view the parameters Pathfinder Office (PFO) uses for any datum transformation, from the main menu choose, Utilities / Other / Coordinate System Manager. Click on the Datum transformations tab and select the transform of interest.

NAD83 (CONUS) CORS96

In the Continental US and Alaska, choose this transformation in PFO to move data between WGS-84 (G1150) and NAD83 (CORS96).

NAD83 (CONUS), NAD83 (Alaska)

These are both null transforms in PFO. All parameters are held at ZERO and data does not move at all. Despite different names, they are functionally equivalent in PFO.

NAD83(PacP00), NAD83(MarP00)

NAD83(PacP00) is for users on the Pacific plate, which includes the Hawaiian and Marshall Islands and American Samoa. This transformation was updated in the last days of 2008 and was incorporated in PFO as NAD83(PacP00 Epoch 2003.) BUT with incorrectly.  Please see these notes add the corrected parameters to Pathfinder Office. They must be added manually to all versions of Pathfinder Office.  All users must manually add these parameters as the even the most current version of PFO.  Even the parameter in the latest Pathfinder Office 5.0 are incorrect.  Instructions for this are included in the Datums Cheatsheets section of this site. For users on Guam and others on the Mariana plate, use NAD83(MarP00). 

         Be sure to see important PacP00 updates as of Jan 2011!

NAD83 (Hawaii), NAD83(Aleutian)

These transformations are only gross approximations in PFO and should not be used at all.
