Wintec WBT-200 Multi-Function GPS Data Logger
Wintec WBT-200 Multi-Function (3-in-1) GPS Receiver
Wintec WBT-200 is a mult-function Bluetooth GPS data logger in an ultra compact form factor. The stand-alone track recording function is independent from any host and can be operated with Bluetooth off. The recorded track can be configured and even uploaded to Google Earth automatically with the bundled GPS utility.
I’m tempted to pick one of these up soon to carry when I’m taking photographs. There are drivers available for Linux and OS-X that allow one to download the data. It’d be easy to write a script to match up the EXIF timestamp and the data log to geotag photos before sending them to Flickr.
Driver info is here.
