Gpicsync is a tool to automatically tag photos with geographical location (if you've got a GPS dongle).
From http://code.google.com/p/gpicsync/
GPicSync automatically inserts location in your photos metadata so they can also be used with any 'geocode aware' application like Picasa/Google Earth, Flickr, loc.alize.us, etc.
Features:
* automatically geocode your photos (in the EXIF header)
* use a GPS tracklog in the GPX format or NMEA format (multiple selection possible)
* Support elevation data if present in the tracklog
* create a Google Earth KML file to directly visualize the geocoded photos and track in Google Earth
* create a Google Maps file to publish your pictures and track on the web (more)
* Automatically associate audio or video files in Google Earth and Google Maps
* create a Google Earth KMZ file (containing your geolocalized pictures and tracklog).
* add additional geonames and 'geotagged' metadata (for automatic tagging in Flickr for example) and create an automatic IPTC caption (more)
* manually write latitude/longitude in a picture EXIF or a selection of photos
* handy tools integrated (Time correction tool, EXIF reader, GPX inspector, rename pictures with date/location,)
* supports Jpeg pictures and main RAW files format (more)
* software available in English, French, German, Italian, traditional and simplified Chinese, Catalan, Russian, Spanish, Polish, Portuguese and Czech (see translations)
