Reverse Geocoding Data and Software
GeoNames street level reverse geocoding for the US is available as web service either free or in a commercial variant with a service level agreement. GeoNames also provides the data and software to run the reverse geocoding inhouse in your own data center and we offer consulting services to help you integrate the functionality in your applications.
Reverse geocoding is used for vehicle tracking, for location based services and other applications where you have a gps signal with latitude and longitude and want to know information about the address or place this location represents.
