Another useful device for geotagging photos, the GiSTEQ PhotoTrackr Lite with GPS uses geo-mapping technology to identify precisely where a photo is snapped. Connect it to your computer and you can then easily upload your geotagged pics to photo-sharing platforms such as Flickr, locr, SmugMug, and Google’s Picasa. Powered by a single AA battery, the PhotoTrackr Lite is so low on power consumption that under normal use a single battery should last you a minimum of 22 hours. It’ll also export pics in NMEA, GPX, KML, and HTML format, has built-in waypoint management, simple Google Earth integration, and multi-language support. How much will it set you back? About $119.
