Playing Back a Log File
After you log a route with your GPS receiver, you can play it back in the mapping
application and review your entire journey on-screen.
Your log will play back in NavMode unless you have it turned off. For more information, see
Using NavMode or GPS Tab View
.
Notes
• You cannot play back a log file if you are currently tracking with a GPS receiver.
• Zooming in on the map allows you to see the log file in greater detail.
• When you play back a log file in NavMode, the tab area is not minimized; this allows
you to control the playback.
To Play Back a Log File
Use the following steps to play back and review a log file.
1. Click the GPS tab and then click the GPS Log subtab.
2. Click Clear Trail to clear any existing GPS points from the map display.
3. Click File and then click Open.
4. Single click the file you want to view.
The bottom of the Open a GPL File dialog box opens the start location, start time,
start coordinate, total distance, duration, finish location, finish time, finish
coordinate, and the number of readings for the selected log. Log files have .gpl
extensions and are saved by default in C:\DeLorme Docs\GPSLogs.
5. Click Open.
6. Click the Play button
to begin playing back your log.
OR
Drag the slider in the Progress Bar (see graphic at the end of this topic) to the
point in the log you want to play.
Note Playing back a log file defaults to 1x, which occurs in real time and takes the
same amount of time as the original trip did; for example, if your trip took six hours,
the on-screen tracking process also takes six hours.
You can also:
• From the Playback Speed drop-down list, select an option (2x, 5x, 10x, 25x,
or 50x) to increase the tracking speed accordingly.
