Upload a Geoid File

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

Connect the field device to which you want to upload. The Device pane displays.
On the pane's toolbar, click Tasks, and select Upload geoid (ggf) file. The Geoid Sub-Gridding command pane displays.
If needed, select the folder containing the installed geoid files in the Folder list, or click the Browse button and navigate to a folder containing .ggf files.
Select a geoid file in the Geoid File list.
Click Upload. The geoid file appears in the Other Files folder of the Device pane's tree.
Note: If the geoid grid file is larger than 1 MB, a confirmation message displays, asking if you really want to upload it. Consider defining a sub-grid of the geoid to make the file smaller.
