Hello all. I just wanted to share a bit of a success story.
I had been searching for a way to geotag my photos from my Nikon D200 raw files (*.NEF). To geotag while shooting, the Nikon solution is expensive and tethered with Garmin devices on the camera, adding weight and heft at the expense of ergonomics. There are also a couple of expensive ($200) Bluetooth dongles for the D200, but again they interfere with ergonomics and drain battery life.
I decided I did not need to geotag my images while I shoot, so I started looking for a GPS logger. I had an older Bluetooth GPS receiver (old i***) that worked great for traveling for navigation on vacations, but it did not log waypoints. Sony's solution was expensive and could not be used a GPS mouse. So, I decided to get a logger that also had Bluetooth. I ended up with the qstarz BT-Q1000.
Now, there is some effort involved in geotagging NEF files. I am currently using a nice bit of freeware appropriately called geotag. Geotag takes GPX files and tags pretty much any photo file that DCraw can read. So, using gpsBabel to convert the BT-Q1000's NMEA file to GPX takes all of about 10 seconds, and then I load the file and match the photos in geotag!
Hope this helps someone else out there! It should also work for other image files, but I have not tested anything other than D70/D200 NEF files and jpegs.
Cheers.
