Allows you to find coordinates with a place name search. Licensing: Geonet Names Server (GNS) Name search: U.S. National Geospatial-Intelligence Agency (NGA) maintains a comprehensive database of non-U.S. place data. The Libre Map Project: The purpose of the project is to aggregate and make digital maps and related GIS data available for free.
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, frequently latitude/longitude pair, to identify a location on the Earth's surface. [1]
Reverse geocoding is the process of converting a location as described by geographic coordinates (latitude, longitude) to a human-readable address or place name. It is the opposite of forward geocoding (often referred to as address geocoding or simply "geocoding"), hence the term reverse. Reverse geocoding permits the identification of nearby ...
Reverse lookup is a procedure of using a value to retrieve a unique key in an associative array. [1] Applications of reverse lookup include reverse DNS lookup, which provides the domain name associated with a particular IP address, [2] reverse telephone directory, which provides the name of the entity associated with a particular telephone ...
The Geolocation API is ideally suited to web applications for mobile devices such as smartphones. On desktop computers, the W3C Geolocation API works in Firefox since version 3.5, Google Chrome, [6] Opera 10.6, [7] Internet Explorer 9.0, [8] and Safari 5. On mobile devices, it works on Android (firmware 2.0+), iOS, Windows Phone and Maemo.

Since ZIP Code boundaries are based on the areas served by each physical post office, they often do not coincide with the boundaries of local government units. For example, suburban and unincorporated areas may share a postal city name with a neighboring municipality, even if no ...
These databases typically contain IP address data, which may be used in firewalls, ad servers, routing, mail systems, websites, and other automated systems where a geolocation may be useful. An alternative to hosting and querying a database is to obtain the country code for a given IP address through a DNSBL-style lookup from a remote server.
The current version of the API, v0.6, was released in 2009. A 2023 study found that this version's changes to the relation data structure had the effect of reducing the total number of relations; however, it simultaneously lowered the barrier to creating new relations and spurred the application of relations to new use cases.
