geotagging and mapping photos

Collecting Photos and Location Data

To begin, make sure that you are familiar with the digital camera you plan to use, that its battery has enough charge, and your memory card has enough space. It is also important to make sure that the clock on your camera is properly set. Before leaving, check the camera's clock against an accurate clock (such as the one on your computer, if it pulls time data from the internet) or http://www.time.gov. We also recommend that you take a photo of the clock on the GPS device so you know when your first photo was taken. (The time that the camera embeds in each photo will later be matched up with your GPS data, and it's useful to know.) We'll show you how to do that next.

When you've arrived at the location you'd like to work at, turn on the GPS device by pressing the power button on the side and hold the unit facing the sky. (If you haven't used the device, or it has been a long time since you've used it, you might want to turn it on earlier in case it takes time to find and establish a satellite link. Once it's established a link, you can turn it off until you want to begin.)

Once it has acquired satellites, press the menu/find key on the left of the device twice until you reach the main menu. Then, use the joystick enter/rocker key to scroll down to the Setup icon. Click the joystick once on top of that icon and you'll be at the setup menu. Use the joystick to scroll over to the Time icon and click on it. Now, take a picture of the GPS device screen, being sure the time is readable in the photo. After you've done that, return to the map by hitting the quit/page key on the right side of the device.

Then, begin walking or driving along your chosen path, taking photos along the way. With the attached cord, you can wear the device around your neck, freeing up your hands.

When you are done, simply press and hold the power button on the GPS to turn it off.
