GPS Data Logger


As an eager Geocacher, I've been the owner of several GPS Receivers over the last years. The last year I've been using a Garmin GPSMAP 60 CSx. In my opinion a very good GPSr with the SIRF-III chipset. I can receive the satellite signal in places where other GPSr give up. However, it's rather bulky and not very convenient to carry all the time.
Some months ago I read about a GPS Data Logger, the GlobalSat DG-100. The only thing it does is to log your position at certain intervals. It has room for 60,000 positions before you have to connect to your computer and download the positions. It's really a simple and compact device. It runs on a couple of AA batteries (two re-chargeable are supplied with the device) and it charges from your computers USB port. The only bad thing about this device is the software. It's not much good, but it's simple and once you learn your way around it, it's easy to download the coordinates.
The DG-100 now lives in my camera bag. Whereever I go with my camera, it goes with me. I uses the PixGPS Photo Geotagger to match the GPX track files from the GlobalSat DG-100 with the EXIF information in the photos. The information is stored in the EXIF meta data of the photo for future reference and I can plot the location of each photo on a map, for example Google Earth.
