Geotagging files with libferris and Google Earth
Geotagging is the association of geographic location information with an object. A geotag comprises three pieces of information: a name and longitude and latitude values. Once files are geotagged, they can be indexed and searched based on the geographic information they contain. Here's how you can tag your photos, documents and other files so you can search for place-related information on your PC using Google Earth.
