Heading on holiday and looking for a way to keep track of your photos without manually writing down location data? You'll probably enjoy a camera with built-in GPS tagging.
This year, most of these GPS cameras are in their second generation, bringing extra features like location tracking and location names on top of the standard latitude and longitude. We've seen most of the major manufacturers push their weight behind GPS tagging; Panasonic, Sony and Canon are the big names that have revealed compatible cameras so far. There's even one SLR in this list.
Most of these cameras will insert the GPS coordinates in the photograph's EXIF data, which can then be placed on a map using a photo editor or viewer, like Picasa, which plots location data on Google Maps.

Don't want to buy another camera? There are also devices such as Sony's GPS-CS3KA that will automatically tag photos once a compatible memory card is inserted. Alternatively, there's technology such as the Eye-Fi card, which can tag your photos with a location. It works by using Wi-Fi positioning to determine where you are — providing that you're in an area where the card can detect Wi-Fi networks.
