    44. 44. Geotagging <ul><li>Geotagging ( Geocoding ) is the process of adding geographical identification metadata to various media such as websites, RSS feeds, or images. This data usually consists of latitude and longitude coordinates , though it can also include altitude and place names </li></ul><ul><li>Geocoding also refers to the process of taking non-coordinate based geographical identifiers, such as a postal address, and assigning geographic coordinates to them (or vice versa). </li></ul>
