Shift an entire layer with Global Mapper

Sometimes I have to provide sample geospatial data to vendors for product testing or for troubleshooting software problems. But I do not want to give them the actual location of the data, in which case I have to move the data away from the actual geographic location. Global Mapper provides a simple layer shift command to do this but it is hidden away in a pop up menu some where. To do this, do the following:

  1. Start up Global Mapper. Open up the file for shifting.


  2. If the Overlay Control Center is not displayed, press ALT+c.

    The Overlay Control Center is displayed.

  3. In the Overlay Control Center list box, mouse right click on the layer to shift.

    A pop up menu appears.

  4. Choose Shift Selected Layer(s) a Fixed Distance.

    The Specify Offset to Apply to Point(s) dialog box appears.

  5. In the X/Longitude Offset field, type in the horizontal offset, e.g. 1000.
  6. In the Y/Latitude Offset field, type in the vertical offset, e.g. 2000.
  7. Click OK.

    The layer is shifted.
  8. Save the layer.
