To customize the coordinate system database

You can customize the coordinate system database used by the Origin software. This enables you to:

  • Reduce the number of coordinate systems available so that it includes only the ones you need.
  • Customize existing coordinate systems definitions or add new coordinate system definitions.
  • Include GNSS site calibrations in the coordinate system library.

You must use the Coordinate System Manager software to modify the Coordinate System Database (CSD) and then transfer the modified database to the System Files folder on the controller. When a custom.csd file exists in the C:\ProgramData\Spectra Geospatial Data\System Files folder, the Origin software uses the custom.csd database instead of the coordinate system database built into the software.

The Coordinate System Manager software is installed with the Spectra Geospatial Survey Office software.

  1. Run the Coordinate System Manager software on your office computer.
  2. To hide the required element:
    • Coordinate system: In the left pane of the Coordinate Systems tab, select the coordinate system(s) that you do not want, right click and then select Hide.
    • Zone: In the left pane of the Coordinate Systems tab, select a coordinate system, from the right pane, select the Zone(s) you do not want, right click and then select Hide.
    • Site: From the Sites tab, right click the site(s) you do not want and then select Hide.
  3. Select File / Save As.
  4. Name the file custom.csd and then click Save.

By default, the file is saved in C:\Program Files\Common Files\Spectra Geospatial\GeoData with the extension *.csd.

  1. Run the Coordinate System Manager software on your office computer.
  2. Select File / Export.
  3. Select User‑defined records only and then click OK.
  4. Name the file custom and then click Save.

By default, the file is saved in C:\Program Files\Common Files\Spectra Geospatial\GeoData with the extension *.csw.

If a GNSS site calibration has been saved using the Survey Office software, a site with the assigned name is added to the Sites tab and a Site group is created in the Coordinate Systems tab, if required. When you create a customized coordinate system that includes sites saved by Survey Office, include those sites created in the Sites tab. The Site group in the Coordinate Systems tab contains the coordinate system details referenced by the sites saved in the Sites tab, but the calibration details are only stored in the site in the Sites tab.

Transfer the custom coordinate system file to the controller. The file must be called custom.csd For the Origin software to use it, the file must be in the C:\ProgramData\Spectra Geospatial Data\System Files folder and named custom.csd.

  1. In the Select coordinate system screen, select Select from library. Tap Next.
  2. If this is a new custom.csd file, a warning appears. Tap OK.
  3. In the System field, select [User sites].
  4. In the Site field, select the required site.
  5. If required, select a geoid model.
  6. Tap Store.
