Geocoding is the process of converting descriptive location information (such as a text address line) into geographic positioning data (such as latitude and longitude coordinates) that can be mapped and placed on the earth. These coordinates can also be assigned to other geographies to provide more information on the location, such as which county the point falls within. The example below shows only a few of the many types of spatial information available.
