Have you ever gotten home after a photo excursion and could not remember exactly where you took that great image? Maybe you just want to see your trip laid out on a map for you with thumbnails. Geotagging your files may be the solution for you! Some cameras like the Nikon P6000 and Sony XR520 have GPS units built-in which will place your coordinates into the metadata of the files they produce. If I had to wager, I'd say that within 5 years almost ALL cameras will have GPS built-in. There are ways to get geotagged files with your current camera too! If you have a Nikon DSLR, you might be able to plug their GP-1 accessory unit in to automatically geotag your photos. Fear not if you don't own a Nikon, though, because Sony makes a unit capable of tagging ANY camera's photos, the GPS Image Tracker. You carry this small device with you as you take photos or video and either insert your card into the GPS Image Tracker or synchronize on your pc. It compares the time data of your photo with it's own log to figure out where you were and when. It's Geotagging!
