Geotag your photos using Trails on the iPhone
What is geotagging and geocoding?
Geotagged or geocoded photos are marked with the location at which they have been taken. So when you share your pictures online (e.g. via Flickr) others can immediately see on a map where your photo has been taken.
Photos taken with the iPhone's built-in camera are automatically geotagged. However, if you take pictures with your normal digital camera the photos will be missing this geographical information. This is where Trails can help.

How can I use Trails and my iPhone to geotag photos?
Geotagging on the iPhone can be so simple:
- While you are out and about with your camera, let Trails track your path and movements:
- Make sure that your camera and the iPhone have the same date, time and timezone set.
- Start your iPhone and launch trails
- Create a new track by touching the plus symbol
- Before starting to walk open the track by touching its name and click "Record". Your movements are now being recorded.
- Leave the screen and the iPhone on. Put the iPhone into your pocket where you are sure not to accidentally push the home or sleep button.
- Once you have finished your walk stop tracking by sliding the stop slider to the right
- Now export the track to your email as GPX by touching the export symbol on the track's main screen. (Make sure to leave Trails running for a few seconds to allow full transmission of the track.)
- You should receive an email containing a GPX file.
- Open that GPX file in HoudahGeo (Mac), Geosetter (Win), GPSPhotolinker (Mac) or the like. I strongly recommend HoudahGeo and use it myself in conjunction with Trails.
- Open your photos in the same software and follow the synchronisation procedure. Click the links above to learn more about how to do this.
- Done!
