Address geocoding
Address geocoding, or simply geocoding, is the process of taking a text-based description of a location, such as an address or the name of a place, and returning geographic coordinates (typically the latitude/longitude pair) to identify a location on the Earth's surface. Reverse geocoding on the other hand converts geographic coordinates to the description of a location, usually the name of a place or an addressable location. Geocoding relies on a computer representation of address points, the street / road network, together with postal and administrative boundaries.
The geographic coordinates representing locations often vary greatly in positional accuracy. Examples include building centroids, land parcel centroids, interpolated locations based on thoroughfare ranges, street segments centroids, postal code centroids (e.g. ZIP codes, CEDEX), and administrative division Centroids.
Geocoding – a subset of Geographic Information System (GIS) spatial analysis – has been a subject of interest since the early 1960s.
In 1960, the first operational GIS – named the Canada Geographic Information System (CGIS) – was invented by Dr. Roger Tomlinson, who has since been acknowledged as the father of GIS. The CGIS was used to store and analyze data collected for the Canada Land Inventory, which mapped information about agriculture, wildlife, and forestry at a scale of 1:50,000, in order to regulate land capability for rural Canada. However, the CGIS lasted until the 1990s and was never available commercially.
On 1 July 1963, five-digit ZIP codes were introduced nationwide by the United States Post Office Department (USPOD). In 1983, nine-digit ZIP+4 codes were brought about as an extra identifier in more accurately locating addresses.
In 1964, the Harvard Laboratory for Computer Graphics and Spatial Analysis developed groundbreaking software code – e.g. GRID, and SYMAP – all of which were sources for commercial development of GIS.
In 1967, a team at the Census Bureau – including the mathematician James Corbett and Donald Cooke – invented Dual Independent Map Encoding (DIME) – the first modern vector mapping model – which ciphered address ranges into street network files and incorporated the "percent along" geocoding algorithm. Still in use by platforms such as Google Maps and MapQuest, the "percent along" algorithm denotes where a matched address is located along a reference feature as a percentage of the reference feature's total length. DIME was intended for the use of the United States Census Bureau, and it involved accurately mapping block faces, digitizing nodes representing street intersections, and forming spatial relationships. New Haven, Connecticut, was the first city on Earth with a geocodable streets network database.
In the late 1970s, two main public domain geocoding platforms were in development: GRASS GIS and MOSS. The early 1980s saw the rise of many more commercial vendors of geocoding software, namely Intergraph, ESRI, CARIS, ERDAS, and MapInfo Corporation. These platforms merged the 1960s approach of separating spatial information with the approach of organizing this spatial information into database structures.
