Coordinate system settings

To avoid issues with your data, do not change the coordinate system once nodes have been added to the project.

You can change coordinate system settings when:

  • Creating a project
  • Starting Penmap, if the Show at startup check box is selected in the Coordinate system dialog.

To change the coordinate system settings for a project that does not yet have nodes added, exit the GNSS method then touch-hold the GNSS button , tap and then select Coordinate system:

  1. Select the System. To view more detailed information about the selected coordinate system, tap Info.
  2. Select the Zone, Datum, and Geoid. By default the software shows a selection of systems, zones and datums appropriate for your location. To view more options, select the Show all CRS check box.
  3. Tap Next.
  4. If prompted to download files for the coordinate system you selected, tap Download.

If the coordinate system you need is not available, you can create it using Trimble Coordinate System Manager. This software can be installed to your desktop computer with the Penmap Project Manager software using Trimble Installation Manager for Windows. See To install Penmap Project Manager. For more information on creating your own coordinate system, refer to the User Defined Coordinate Systems support bulletin.
