If you watch the josm-rawgpstracks tutorial screencast that you can find here on Imi’s website (or on a mirror), you can learn about a neat JOSM feature: the ability to position photographs geographically based on comparing their timestamp to the GPS logs. Which is a pretty neat way to “geocode” photos.

This isn’t rocket science, of course, and the use in JOSM is primarily for the utility it offers in helping to name ways within JOSM. Next I’m off to look for open source tools that will let me merge my GPS trace information with my photos and end up with EXIF data within the photos themselves that indentifies their location.
