On a recent trip to the Southwest National Park in Tasmania, I tested the GlobalSat BT-335 GPS and used it in a datalogging capacity. By simply synchronising the time on your camera with the time set on the GPS unit, it is possible to automatically geotag your images with location information when you arrive back in the office. After downloading the GPS Tracklog data from the GPS and the captured photos to the PC, the free Geotagging facility LOCR was used to automatically geotag my photos taken on the walk with the GPS coordinates logged with the GlobalSat BT-335 GPS.
At a click of a button you can also view your photo points in Google Earth.
The BT-335 proved to be a reliable option for capturing GPS information to be linked with captured images. With 25 hours of battery life and a capacity to be used as either a stock standard Bluetooth GPS or a datalogger, the BT-335 is a great GPS option for fieldwork and travel alike.
