Importing GPS Data

GPS data received in an ASCII file format can be imported into MX by using the MX Data Import add-in. This program will read the file data and create one or more point strings from the information.

From the Add-In menu select Personal Add-Ins then MX Data Import. If MX Data Import is not available, then it will need to be installed.

Installing an Add-in

  • From MX's Add-Ins menu, select Personal Add-Ins, then Add-In Manager...
  • Click the Add... button on the next panel.
  • Click the ellipsis button button at the end of the line labeled .EXE File Name.
  • Browse to the add-ins directory of the MX workspace.
  • Select the desired program and Open.
  • Click the OK button and Close the Add-In Manager
  • The program will now be available on your Personal Add-Ins menu
