WHAT IS GEO-TAGGING, ANYWAY?

From Wikipedia:

GeoTagging, sometimes referred to as 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 placenames.

Geocoding also refers to the process of taking non-coordinate based geographical identifiers, such as a postal address, and converting them into geographic coordinates.

GeoTagging can help users find a wide variety of location-specific information. For instance, one can find images taken near a given location by entering a latitude and longtitude into a GeoTagging-enabled image search engine. GeoTagging-enabled information services can also potentially be used to find news, websites, or other resources.
