The GPS Travelogue
This is the device that uses GPS to track and record everywhere you travel, allowing you to later upload your journey to online mapping applications such as Google Earth. It stores locations in real time on its built-in 64MB flash memory at intervals you determine between one second and 59 minutes, holding up to a total of 260,000 waypoints, including altitude, speed, time, and distance. Small enough to fit in your palm, it can easily store in a pack, purse, or pocket.
