Geotagging Photos
Unlike some camera phones, most consumer and professional digital cameras do not support tagging photos in EXIF/IPTC with geographic location. Nikon seems to be ahead of the curve here, but hopefully others won’t be far behind.
But I think I found what may be a better solution: the $250 TrackStick GPS Data Logger. It’s a tiny GPS receiver with a USB-only interface, it records location continuously to its 1MB internal memory using AAA batteries and exports its log in a variety of formats.
With this device, photographers could just write a little Perl script (using ExifTool) to go through a folder of JPEG or RAW photos, match up the EXIF timestamp with the GPS location log, and add geocode tags.
Considering Nikon charges $130 or so just for the cable to connect your camera to a compatible GPS device, this looks like a much better solution for travel photographers and photojournalists.
