The GeoTrack tool contains two tracking tools: Start GPS Track and Hide/Show Flag. The Start GPS Track tool allows you to track the map position of an attached GPS device. Hide/Show Flag displays or hides a flag (marker) that shows your current GPS location on the map.
For instructions on how to access the GeoTrack tool, see Accessing the GeoPDF Toolbar.

Enabling Windows Location Services
The GeoTrack tool uses Windows Location Services to determine the location of your device. Before the GeoTrack tool can track your position, you need to enable Location Services and update your preferences in Adobe Reader.
Enabling location services on your PC
On your PC, navigate to Start > Settings > Privacy > Location. Switch the Allow apps to access your location setting to On. For more on Windows Location Services, see Microsoft's Windows 10 location service and privacy guide.
Disabling Protected Mode in Adobe Reader
Open Adobe Reader and navigate to Edit > Preferences > General. Deselect Enable Protected Mode at startup.
Allowing GeoPDF Toolbar to access your location
In the GPS Options pane of TerraGo Preferences, select AutoDiscover. For more information, see the GPS Options in Setting TerraGo Preferences.
Using a GPS device
To use GPS tracking with a GPS device, your GPS device should display coordinates in the same datum as your GeoPDF file. The projection, however, does not need to be the same. For example, the GPS device may display latitude and longitude while your file displays UTM.
Your GPS device must be able to operate with NMEA-compliant mapping programs via a virtual COMM port. You can obtain the necessary software from the vendor of your GPS device. You may also be able to use other software such as Garmin's Spanner software, their Oregon software, or GpsGate's Client.
Starting GPS tracking
From the TerraGo GeoPDF Toolbar, click GeoTrack , then Start GPS Track .
A check mark will appear to the left of the Start GPS Track menu option.
In the GeoPDF Map Frame Selector dialog box, select the map frame in which the GPS device should track your location. (Note: Only NMEA compliant strings are supported.)
Click GPS Track.
Click GeoTrack, then Start GPS Track to stop tracking your location.
Hiding the GPS location flag
When you start GPS tracking the Show Flag menu option is selected by default and a flag shows your current GPS location on the map. The flag appears as a crosshair and your position refreshes according to the value in the Poll Interval: Seconds text box in the GPS Options pane in the TerraGo Preferences dialog box. To access this dialog box, from Edit on the main menu, click Preferences, then TerraGo. Modify the interval value as needed and then click OK.
From the TerraGo GeoPDF Toolbar, click GeoTrack, then Hide Flag .
A check mark will appear to the left of the Hide Flag menu option.
Click GeoTrack, then Show Flag to see the crosshair that represents the current GPS location on the map.
