If the receiver just listen, how does it find the satellite? The logger also use gps chipset to communicate with the satellite and when it finds 3 or 4 satellites together, it will get a precise location data. And it will record this data at the time interval set up before. And some direct geotagging gps devices like mentioned above, EasyTagger GPS, do the same thing, just they got the cable to communicate with the camera.

@Tulio: Thanks for the explanation. We find ourselves having to describe the difference between the logger (receiver) we carry and what everyone associates with a GPS device — namely a transmitter/receiver that features maps and current position.

The GPS logger is just a receiver. It doesn’t talk to satelites, otherwise it would need stronger batteries. The satelites send time information. The receiver gets the time from several satelites. When the receiver is closer to one satelite, the other one is gonna look late, and that’s how the receiver knows where you are. It’s by knowing how fast the information takes to come from each satelite. That’s why the more satelites, the better. That’s it. Each satelite send the correct time: they just inform what time it is. The GPS receiver just listens.

It’s a great device, I like the Easytag Gps Unit, it’s really perfect partner when I hiking outdoor.

Here is a product absolutely worth recommending. It is called Easytagger (www. e-geotag.com). For first, it can direct input GPS information into photos taken by certain Nikon cameras and no need for matching. Second, it has a 2 G TF card to store at least 2 years traits. Third it uses barometric altitude, you can get a very accurate height figures.

Great article! I like using GPicSync myself – I think the interface is better than the Sony GPS software.

You’re right, traveling with a laptop has its advantages and disadvantages. For us, it’s a necessity, but for shorter trips that’s a harder call.

If the trip is relatively short (i.e., less than 15 days), you could just take the GPS logs off the device after the trip. For longer trips without a laptop, you could hop into an internet cafe, connect the GPS device to the computer’s USB port and copy the files to a USB flash drive or CD/DVD (if you’re backing up photos anyway).

We just had an interesting experience this evening at the Hindu temple in Melaka, Malaysia. I have a feeling it’s just a small taste of what’s to come once we’re in India proper!
Have fun preparing for your next trip!

Thanks, Audrey. After having my camera stolen once (in Panama City), I’ve gotten more cautious about carrying a laptop… and sometimes I just fill up my camera’s memory cards, review the photos tto delete bad ones, then transfer the photos to two sets of CD/DVDs at a cybercafe, snail-mail one set to home, and wait until I’m home to work on the photos. (If I ever get the chance again to travel as much as you and Dan are, though, I wouldn’t want to wait so long to sort my photos, for sure!) It’s good to know that there’s a batch-processing option like this… maybe I could get a cheap laptop to handle that part and not worry too much about losing it?

i’ve heard so many great stories about India… can’t wait to see your stories and photos!!

Hi Jerry!
You are right in that the Sony GPS-CS1KA won’t connect directly to your Nikon D200 to embed the latitude and longitude data directly into the EXIF data of the photos. However, if you want to avoid expensive cables, you can still use the Sony GPS device in the way described in this case study – attach it to your camera bag or belt loop and do the batch geotagging on your laptop based on the time stamp on the photo and in the GPS logs. Whichever way you choose to do it, it’s pretty cool to see the Google Maps and topographical information of everywhere.

We leave KL tomorrow for Melaka and then we have a few days in Singapore before exploring India. Should be a pretty wild next couple of months.

Have fun planning your next adventure!

Hi over there (wherever “there” is by now :), Dan and Audrey. You’re encouraging me to get busy on geotagging before (with luck…) I head for the boonies myself this Spring.

My camera is a Nikon D200; iI think the Sony GPS gadget isn’t compatible. A quick Web search found lots of information for my camera — which, like most Nikon cameras, has verrry expensive accessories. I thought I’d mention one page from a do-it-yourselfer who managed to get around Nikon’s high price ($150 for a cable!?) — and to give other info about hooking a more-generic GPS device to a camera. His page is http://www.core5.net/projects/d200GPS/ . (I haven’t tried his method yet, by the way.)

Happy trails…
Jerry
