Unfortunately, some people don’t have a geotagging feature on their present model of digital camera, but you can compensate for it with the i-gotU GT-120.
The i-gotU is a GPS tagger that the user puts on his or her person somewhere. Once it is switched on, it will record not only where you were, but when. If the clock on your camera is synced with the clock on the i-gotU, then you will have an accurate record of where you have been.
Of course, you will have to match the time of the picture with the time on the i-gotU later, but you basically have a poor-man’s (or woman’s) geotagging system. All you need to do is plug in the i-gotU into your USB slot on your PC (i-gotU is not Mac compatible), and you can upload the coordinates of your trip into Google Maps/Earth, Flickr, or any other social networking site.
The i-gotU uses a SiRF Star III chipset, and can also be used as a Bluetooth GPS receiver with a compatible mobile device. It is also water-resistant, so you don’t need to worry about water damage on your trip.
If this sounds like something you might be interested in, then you should be able to purchase the i-gotU GT-120, as well as the more advanced GT-200 at the company’s website.
