Grazer allows you to sort pictures dependong on the place where they were taken using GPS information from a GPX-file. The software writes GPS-GeoData into the Exif information of your digital pictures and automatically synchronizes them with the GPS-Data. Even neater is the Exif Mapper application that the Grazer team have developed using Google Maps. It’s currently in Beta, but looks like a great way of visualising where particular photos were taken.

Thanks to Jens Schwoon for letting me know!
