Geocoding digital photos has become a popular thing to do. It makes sharing of photos in applications like Google Earth very easy. Some suggest that it’s helpful for buyers of stock photos in finding images but I’m not sure I completely see the connection there. Are stock buyers searching based on geo. coordinates? Maybe some folks could weigh in on that one.
Anyway, I began geocoding my photos about a year ago. It’s another step in the workflow but it’s reasonably automated so not terribly onerous. In my case, I used my Garmin eTrex Vista HCx which has route tracking capability and GPicSync. GPicSync uses .gpx track files which is what my eTrex creates. The workflow goes like this – Load images from the CF card to the computer via Lightroom (adding copyright, keywords, etc). Transfer the .gpx track file to the computer. Launch GPicSync, point it at the track file, point it at the folder with the image files, let it do its thing. Easy peasy. I set the eTrex to record a track point every 10 seconds. In GPicSync, I set the threshhold for time difference between track points in the track file and the time code in a particular image file at 10 seconds. GPicSync then writes the long/lat coordinates into the EXIF if the difference between the two is less than 10 seconds. In order for this to be successful you have to sync the time in your camera with the GPS time in the GPS receiver you’re using, be it something like my eTrex, a smartphone or a small GPS tracker like those from Trackstick.
