Techopedia Explains Geocoding

Geocoding is typically implemented through geocoder software that performs the task of finding geographical coordinates from a geographical information system (GIS). Typically, geocoding works by taking the address as an input and searching for it within the geographical information system (GIS).

The GIS usually contains the geographical coordinates for that particular address. Geocoding then interpolates the position of the address in formal of geographical coordinates. These coordinates include the longitude and latitude of the searched location or address.
