Some dear friends from Australia just passed through Ithaca on a tour of North America, so we took them around to our picturesque gorges and waterfalls, where they snapped picture after picture of the falling, flowing water, something of a novelty to people from arid parts of the world. They had already accumulated 10-12 gigabytes of photos on their trip and with another four weeks to go, I can only imagine how many they'll end up with. But that poses a problem - how will they remember in the future whether a particular beautiful landscape was from Ithaca or Hammondsport, or whether a close-up of some flower came from Montpelier, Vermont or Jasper in Alberta?
One solution could come from HoudahGeo, Macintosh software that helps you "geocode" your photos - attach latitude and longitude coordinates to them - by matching the date and time stamps on the photos to a GPS track, by using Google Earth to point at the correct locations, by using HoudahGeo's built-in map, by connecting photos to GPS waypoints, or by entering coordinates manually. Once photos are geocoded, you can use that information to browse and find particular photos, and you can also publish your photos directly to Flickr or for viewing with Google Earth.
