GPS Correlate

GPS Correlate is a program to match a recorded GPS track with the EXIF tags in digital camera photos, and update the EXIF tags with the location that the photo was taken. It does this by using the timestamp in the photo and finding a data point in the GPS track that matches, or interpolating a point between two other data points.

GPS Correlate was originally written in 2005, updated for a few years, and then abandoned.

Recently, the code was moved to the GPS Correlate repository on Github and another maintainer took it over, and is updating it for the future.
