HoudahGeo "pins" photos to locations where they were taken. Professional grade processing. Mac ease of use. Just like an expensive GPS camera, HoudahGeo can store latitude, longitude and altitude information right within the image file - invisibly with no loss of quality. HoudahGeo writes EXIF, XMP and IPTC tags. HoudahGeo projects may be published to EveryTrail or viewed and shared using Google Earth. Geotagged photos may be saved to Evernote or uploaded to Flickr or locr.
