With Smugmug, both Google Maps and Google Earth can be used to look at the photos the drawback is that the displayed pictures are small and you have to go go back to the Smugmug page to see the photos in a reasonable size. Once I had the photos tagged with the geographic coordinates, I had two options to display them in the context of a map: either relying on Smugmug, the photo-hosting web service that I use, or on a cool iPhoto plugin called iPhotoToGoogleEarth. It is important, of course, to record a fairly large number of GPS points when you are taking the pictures. You can choose between ‘snapping’ photo locations to the nearest GPS datapoint or to interpolate between two points to find the best estimate for the place where the photo was taken. GPSPhotoLinker finds the GPS points that are the closest in time to the time stamp of the photograph and writes the latitude and longitude into the EXIF header of the jpeg file. After that, everything went pretty smoothly. GPSPhotoLinker apparently is not able to just ignore this part of the GPX file the only solution was that I manually deleted all the saved tracks from the GPX file. The problem was that some of the tracks on the GPS unit were actually saved - and saving tracks on a Garmin GPS unit (and maybe on other units as well, I don’t know) results in losing the time stamp from each datapoint. I tried to open the GPX file in GPSPhotoLinker, but it did not work. For some reason, GPSPhotoLinker did not do this for me so I downloaded GPSBabel, connected my Garmin Vista Cx to the iMac, and saved the tracks in GPX format.


After downloading and installing this nice little program, the next step is to get the GPS tracks from the GPS unit.

The key piece of software is GPSPhotoLinker, written by Jeffrey Early.

Before I forget how I did this, here are some notes on the process. Not long ago I managed to georeference some of my photos using GPS measurements.
