Tagging Photos With GPS Coordinates
ptorrone writes "As part of a camera mod project to make a low-cost aerial photography device we started finding other uses for the camera hack. This first part of this series is tagging photos with GPS coordinates by automating a camera and GPS unit, it's a DIY Black Box for now with interesting applications and other uses. Ideally, this may encourage the next EXIF data schema to support GPS and other information."
I wrote an app that tags my images based on GPS coordinates from my Garmin Forerunner. If you look in the EXIF spec you'll find that there are tags for latitude, longitude, and altitude (all of which the Forerunner gives you).
.NET flavour.
If you're using GDI+ on a Windows machine you can add the tags into your image pretty easily using either native code or your favourite
