Upload a Datum Grid File

Select a datum grid file (.dgf) based on the datum used in the project's coordinate system, and upload it to a field device.

To upload a datum grid file:

  1. Connect the field device to which you want to upload a geoid. The Device pane displays.
  2. On the pane's toolbar, click Tasks, and select Upload datum (.dgf) file. The Datum Gridding command pane displays.
  3. If needed, select the folder containing the installed datum files in the Folder list, or click the Browse button and navigate to the folder.

    Note: The default location for .dgf files depends on your operating system:
    In Windows® XP or earlier: C:\Documents and Settings\All Users\Application Data\Trimble\GeoData unless you have previously installed Trimble® Geomatics OfficeTM (TGO). If you have installed TGO and then this software, the path is C:\Program Files\Common Files\Trimble\GeoData.
    In Windows VistaTM: C:\ProgramData\Trimble\GeoData\ or C:\Program Files\Common Files\Trimble\GeoData\.

  4. Select a datum grid file in the Datum Grid Files (.cdg) list, if the datum you need isn't in the list, create a datum grid file.
  5. Click Upload. The datum file appears in the Other Files folder of the Device pane's tree.

Note: If you use the datum associated with your project's coordinate system, but do not create a datum grid file, it will not be saved in the list of datum grid files available the next time you upload. If it is a datum you will need again, create a datum grid file that will be saved.
