Geocoding is the process of identifying geographic coordinates from other geographic data, such as street addresses or zip codes. When the geographic coordinates of physical data points (e.g., home addresses) are known, various attributes of each data point may be displayed on a geographic map containing the data point. The geographical pattern display of the attribute may show regional variations of the attribute. Briefly, geocoding converts a textual description of an address into a coordinate in a coordinate system.
