If you’re looking for an easy (PC free) way to geotag your pictures, the GPS Photo Finder from the ATP sounds pretty good. You just sync up your camera with it’s clock, let it got a lock on the location and you’re good to go. It works through applications like Picasa and Google Earth.
Once you’re set up and have taken some pictures you simply load in your SD, MMC or Memory Stick and it will tag your photos with the latitude and longitude coordinates. It has a 128MB and works for around 550 hours.
Looks like it’ll be on the market sometime in early 2008. I don’t have a price but it seems like a handy little item to have to me.
