TEMS Investigation can load planned routes for drive testing created in the GPX format. The point of doing that is to have the routes displayed in a Map window as a driving aid, so that you do not have to rely on your GPS to follow the correct route.

Loading a GPX route is especially valuable during scripted logfile recording that switches to a new file at regular intervals. The trail of route markers drawn on the map only reaches back to the start of the current logfile; but with a GPX route displayed you always have the entire drive test route in view.

Alternatively, you can load the track of an actual test drive which has been saved in GPX format. That track will then serve as a planned route. The track recorded in a TEMS Investigation logfile (*.trp) can be extracted to a GPX file using the RouteFinder utility; see the Utilities volume, section "RouteFinder".

In what follows, we first describe one method of creating GPX-format planned routes (section "Creating GPX Files"), then go through the mechanics of importing a GPX-format route or track into TEMS Investigation and how it is presented (section "Loading GPX-format Planned Routes or Tracks into the Map Window").
