Geocoding API is a web-based API for georeferencing addresses. It can be used to geocode addresses, and to perform reverse geocoding. The response returned by Geocoding API includes latitude and longitude information. Developers can build geocoding requests by following examples in the Developer's Guide. The response will be returned in a human-readable format. The Developer's Guide also provides information on building geocoding request URLs.
Google offers both a free and a paid geocoding API. For paid accounts, contact their sales team. Google is like the Ferrari of geocoding APIs. It's capable of completing some impressive tasks at lightning speeds. Users may be willing to deal with some limitations and clunky APIs in exchange for the high speed of Google. So, what are the options for geocoding? The answers to these questions are as varied as the features of geocoding APIs.
For the most accurate results, geocoding api providers must use address format best practices. For example, a query value must be at least two characters long. If the value returned is ambiguous, geocoding errors will occur. In such cases, geocoding providers can use address interpolation. Alternatively, they may use the centre point of a street feature as a fallback. These two methods should be used in combination. Geocoding API users will typically accumulate one API request per keystroke. This can be avoided by setting an application to make a Geocoding API request every time a character is typed. By default, autocomplete counts each keystroke as one request. In this case, applications should limit the number of requests they make. If the boundary box is more than 180 miles across, an application should limit the number of requests it makes. Geocoding API supports ISO 3166 alpha 2 country codes.
