How to Geotag Photos

MAKE: Blog has a geotagging tutorial that covers every step of the process and several different web services: taking the photo, getting the lat/long coordinates from a GPS or Google Maps, uploading the photos to Flickr, adding the lat/long coordinates as tags, and viewing the photos on a map from either Mappr or Google Earth. While there are a lot of steps, it’s really not that difficult; sooner or later, though, someone’s bound to simplify the process (a cameraphone with a built-in GPS would do the trick, with the right software).
