GPS functions are quickly becoming commonplace in digital cameras. This feature records a photo's location into the file's metadata. Some cameras, such as models from Casio, Panasonic, and Samsung, even allow you to see your photos on a map within the camera; it's helpful if you want to map out your images or just jog your memory about where you took a shot.
Conveniently, the technology is showing up in rugged point-and-shoot models such as the Panasonic TS3 and Pentax Optio WG-1 GPS, which lend themselves well to adventurous treks. The Canon PowerShot SX230 HS (that company's first GPS camera) and the Sony DSC-HX9V store altitude, longitude, and latitude. Taking the technology a step further, the new Panasonic Lumix DMC-ZS10 shows 1 million international landmarks and points of interest. In addtion, we've reviewed the GPS-capable Casio Exilim EX-H20G, which has an excellent in-camera mapping interface to go along with an extensive points-of-interest database; like the Canon model, it also comes with a "logger" feature, which tracks the camera's movements even when you aren't snapping pictures.
