I just love gadgets. That’s why it’s nice to find that I bought a Garmin eTrex a long time ago. Haven’t used it in years, but then when Apple released the latest version of iLife 09 with the map function in iPhoto I realized that it is very cool to have all the images geo tagged. So I found a program called GPSPhotoLinker, a program that downloads GPS data and pictures and by the date/time on the pictures manages to add longitude and latitude information in the picture info. When you import pictures with this information iPhoto can use that to show it on maps and make it searchable. And when you upload pictures to Flickr, it also uses the location information place your picture on a map. Very cool.
The software is free to download here. If you have an old GPS receiver like me, you need a serial cable (I made my own because of the very high prices for ready made cables), just check eBay. You also need a USB to serial converter, like the “Keyspan High Speed USB Serial Adapter.
To start tagging, just power on your GPS receiver when you start (I just put it in my shirt pocket) and then photo away). Set the clock in your camera (check the GPS clock, it’s VERY exact ) because this is information that is used to sync position information.
Download all your pictures in a folder, connect the GPS, start GPSPhotoLinker and download data from the GPS, and then select the folder with pictures you took. Press “batch” and your done!
