About Geotagging
PhotoLinker adds geographic information to photos, known as geotagging [wikipedia.org]. PhotoLinker also automatically enters the city, state and country into the metadata based on the latitude and longitude, this is known as reverse geocoding.
Why geotag?
You will always know exactly where a photo was taken since the longitude, latitude, city, state, and country are saved to the photo.
Terminology
Location created refers to the location of the camera at the time the photo was taken. This can quite often be distinct from the location shown in the photo, which may be tens of kilometers away.
Location shown refers to the location of the primary object of focus in the image. This may be very different from the location created (such as with a mountain in the distance), or almost the same as the location created (such as a macro shot of a wildflower).
Image direction refers to the direction the camera was pointed at the time the photo was taken. Note that the image direction may differ from the initial tangent of the line between the location created and the location shown. This will be the case if the primary object of focus is not in the center of the image.
Mapped web galleries
Flickr, Picasa, Locr and other websites place geotagged images directly on a map for sharing with family and friends. Check out our examples of mapped web galleries.
Queries
Using Spotlight in Mac OS X 10.4 and higher, you can easily search on any of the metadata right in the Finder. If you search for "Alaska," all photos taken in Alaska will be found because of the geographic information saved to the photo.
Usage
PhotoLinker offers multiple methods for geotagging images. See the geotagging help page for more details.
