I like to geotag my photos, but I don’t always have a GPS. A while ago, I got an eyefi card that can record some geolocation information. However, this is based on the wifi hotspots on the neighborhood and that does not work very well in the wild.
A family gathering with ten different photographers shotting every moment. You end up with thousands of photos that need to be organized at least in sequence over the time (to make a slide-show, for example).
Un appareil photo d’un côté, un tracker GPS de l’autre… il est tentant de combiner les info. Ce n’est pas pratique (ou même pas possible) dans la plupart des cas de connecter directement les deux appareils.
