Creating the GSF in X-Port

To create a GSF (Geoid Separation File) to be used in SurvCE, click on the Tools drop-down and select Geoid Manager.

Geoid Manager

This command will carve out a portion of from a specified Geoid. Since Geoid grids are very large, this procedure will carve out a precise portion of it, to avoid overloading the memory on the remote device running SurvCE. You will be prompted for the approximate latitude and longitude of the job, and the size of the area desired in miles, kilometers or degrees of latitude and longitude. To define a Geoid area, make sure that this criterion is met.

  1. Specify the geoid type.
  2. Enter the latitude and longitude near the center of the job area.
  3. Specify the Grid size (diameter) in miles, kilometers, or degrees.
    Set Geoid Area
  4. Click OK to specify a Name and Location on your PC to save your new .gsf file.
    Please note where the program will be saving your .gsf, as we will need to access that location later, during the transfer process.
  5. Once you have chosen a location to save your .gsf, the program will connect to our server via the internet, to carve the specified area for your grid file. You will receive a message when the process is complete.
