HoudahGeo is a photo geocoding and geotagging tool. Use HoudahGeo to attach GPS coordinates and location names to your photos. HoudahGeo writes EXIF and XMP geotags to JPEG and RAW image files. This creates a permanent record of where a photo was taken. Just like a GPS-enabled camera. HoudahGeo supports many methods of geocoding: Use a GPS track log, reference photos taken with iPhone, or pick locations on the built-in map.
