HowTo: Geotag your photos with the Garmin Forerunner 405

For running, I use a Garmin Forerunner 405. Besides using the watch for sport, I show how you can “geotag your photos”. Geotaging means that you add in the meta information of your pictures the geographic position where you have taken the photo.

How does it work? The GPS track information is compared with the time when your photo as been shot. The X and Y coordinates are stored in the EXIF meta information.

Cookbook:

  1. Preparation: Take your Garmin Forerunner 405 and your digital camera. Take care, that the time of the camera is synchronized with your Garmin watch.

  2. Start your hike. Important: Before you start you have to start the stopwatch (In the training mode). The stopwatch has to run the whole hike; otherwise it doesn’t record your trip.

  3. Back home, you have to transfer the track to your computer: Plug your “ANT-stick” to transfer the data to your Training-Center or the GarminConnect application.

  4. Once the data is imported in your application, you have to export the track to a tcx file.











  5. Convert the tcx file to a gpx file, use:

    or: http://www.gpsvisualizer.com/convert_input

  6. Use gpicsync to add the geoposition to your picture
    Start the application.
    Choose your picture folder.
    Choose the gpx file.
    Start the process (Press “synchronise”).





As a result you have your picture enriched with geographical information and you have a kml file with thumbnails of your pictures along your track.


You can use the kml file with Google maps or Google Earth:

wow nice! i didn't know that there are watches with included GPS modules. How is the battery life of the watch? I don't think it can record a week of traveling, right?

Greetings

As a matter of fact, the battery last "only" for about 8 hours. In order to charge the watch you need a special adapter. For longer hikes or trekking I suggest a real outdoor GPS like the Garmnin Colorado (or similar). The Forerunner is mainly for running or cycling ...

Ok this makes sense as you usually will not run/hike for more than 8 hours, do you?
