Tagging Photos to GPS Data/Tracks
Digital Rebel and Garmin eTrex Vista GPS receiver

Name:	Field test of GPS tagging of photos to GPS data/tracks
Trip Length:	2.70 miles
Average Speed:	2.12 mph
Date/Time:	Tue Apr 06 16:57:52 2004
Workflow:	Used Garmin eTrex Vista, shot with Canon 300d, MacGPSBabel, TopoFusion (via Virtual PC), then I modified the look and content of the HTML export using GoLive and iView MediaPro.

Above is my first field test of tagging GPS data to digital photos. This was done not with a camera with built in GPS system but rather with a standard digital camera and GPS receiver. The general concept is to use the track created by GPS receivers along with the time from the photos EXIF data to match them together. Ideally interpolating between data points for more accuracy. There are number of Mac applications for GPS connectivity, but I could not find one for tagging photos to the GPS data, so I looked at a number of MS Windows based solutions. I'll go into more detail to the various hardware and software options as well as the techniques I used in an article at a later date.
