Bundling GPS Tracks and Geographically Located Photos in KML

Recently I described my effort to add GPS data recorded during a road trip and a canoe trip to Google Maps.  I had written some JavaScript to import my data into a map, with a few options for customization, but felt that there was more that could be done with the data from the canoe trip.  I had a number of photographs from the trip and a desire to map them, along with the GPS data, at the positions at which they were taken.  Although the photographs did not contain any meta-data providing the GPS coordinates for the location at which they were taken, they did contain meta-data indicating the time at which they were taken.  Since I had a GPX file full of time associated geographic positions, I decided to fuse the two together.  


Putting GPS Tracks into Google Maps

After watching a recent episode of Hak5, which showcased Google Maps GPS Mashups, I was inspired to finally do something with some of my own GPS data.  I had GPS data from a canoe trip taken last year and a road trip from a few years ago stored on my handheld GPS with which I had always planned to do something, but just hadn’t had the motivation until now.  While a little simpler than the project described on the show, my initial goal was to draw the GPS track data in Google Maps annotated with waypoints drawn as map markers.  The markers would be used to mark specific locations with descriptive text and images.
