Breadcrumbs provides a free and easy way for you to bring together your GPS tracks, photos and videos.
What is geotagging?
Geotagging allows you to associate a photo/video with a geographical location. This provides huge benefit, as it gives a lot more context for anyone looking at the photo/video. In Breadcrumbs you can really get a feeling for a track, as you can view your photos/videos while also interacting in a 3D world. Geotagging therefore gives you a whole new way of organizing and sharing your media.
How we do it?
There are three ways to geotag photos in Breadcrumbs:
- Photos which were taken on a device which have an inbuilt GPS (such as an iPhone) already contain location data (stored in the Exif data), so Breadcrumbs extracts this information and the photos are geotagged automatically.
- For photos which do not contain any location data we use a different technique. Each point which makes up a GPS track contains not only a geographical location, but also the time at which the point was recorded. Because cameras also record the time when a photo is taken, the timestamp on the photo can be matched with the the associated timestamp on the GPS track, and so your photos can be located in the correct place on the map. This technique requires that the clocks on the camera and video have been synced to the clock on your GPS device, so don’t forget to do this before you start snapping!
- For any photos/videos which are not geotagged by one of these methods, manual geotagging is also possible in Breadcrumbs. All you have to do is drag your photo/video from the thumbnail viewer along the bottom of the page onto the correct location onto the map (see image).
Currently we rely on our users syncing the times on their GPS device and camera/videocamera. We know that this is not always possible so we will be providing a semi-automated solution in the near future to enable you to sync all your media based upon the correct placement of one photo.
