This was a tough one. I wanted to get GPS coordinates into my Exif data. Rather than spend close to $200 for hardware or software, I wanted to find a program that would let me enter the GPS data after I captured it on another device - cell phone, GPS, etc. Easier said than done. Programs I found were either too expensive - $50 to $100 - or not what I wanted. I received lots of suggestions - close, but no cigar. People kept telling me I could drag a photo onto a map - but first I had to know where the photo was taken. Then someone on the photo.net/nikon forum recommended two apps: GPS4cam and Geotag Photo (Lite and Pro). They range from free to $4.00 They both do basically the same thing. You activate the app, and your cell phone records coordinates every 30 seconds, or whatever interval you select. While the app is running, you take photos here and there. I bought both of them. Free is cheaper (obviously), but free apps use lots more battery power by running ads. I got that from BBC News. When you get home, you upload the images to your computer and load the GPS data file onto your computer. With GPS4cam, you take a photo (with your camera) of the barcode that appears on your phone. After the app does its thing, each photo has GPS coordinates in the Exif data. Using Lightroom 4, you can see where the photos were taken and even see the route you followed. I think Google Maps will show locations, too. Of course, each coordinate will not line up exactly with each photo, but it still lets you know if you took a photo in one town or another. Actually, you can get the exact coordinates if you tell the app, either by shaking the phone or pressing a button, to record the coordinates there and then. The apps are available for both Apple and Android devices. I just started using Geotag yesterday, so I have more learning to do.
