I am working on a mapping project for school and this new technology could save me time and energy. Thanks in advance. Save you time and energy i may agree with, but money -- be prepared to spend a few hundred. There are certain GPS devices out there that you may plug into your camera which will record the information with each individual photograph. However, a less costly way to go about doing things and the way I go about doing them when I go hike the barren planes of texas is simply take a GPS with me. If i take a photograph i think is significant i just look down at my GPS and write down the coordinates. I got mine for 150 at best buy, where i work as the digital imaging specialist. |
