This tool helps to geotag photos.
HoudahGeo is a photo geocoding & geotagging solution. It works on the Mac OS X platform. It helps add location lat-long information to the photograph taken. Geo-tagging helps keep the geographic location information along with the photo. Even if you do not remember later, where the particular shot was taken; the photos now carry that information for ever. HoudahGeo can store latitude, longitude and altitude information right within the image file. The data will be invisible and complete. It is able to write into all the industry standard photo files like the EXIF, XMP and IPTC tags. This tool is tightly integrated with Apple iPhoto and Aperture. It also allows for direct access to your Adobe Lightroom catalog. It can help you geotag using EXIF, XMP and IPTC tags for archival and let you publish your photos on Google Earth, Flickr, EveryTrail or locr.
You can publish GPS tracks and photos to Google Earth and be able to view it with eference to the exact location on the earth. While this is an additional and optional information for amateurs like you and me, professionals need to record this information on their photos. This tool really shines when documenting travel. Image a Safari, Animals roaming in the middle of nowhere, etc. By the end of the day, with the information recorded on the images taken, you are able to see a birds-eye view of your journey. You will be able to locate, exactly, the spot where you took the most memorable shot. It has the capability to match photos to GPS track logs and waypoints from GPX, NMEA, Sony LOG, Wintec TES, etc. files. It will be able to match photos to reference photos taken using iPhone. It can do the same with the built-in map and point to the desired location on Google earth. This is a very good tool.
