Geocoding is the process of translating an address to an approximate location in terms of latitude and longitude (approximate is misleading, it can be very accurate). Reverse geocoding is the process of taking latitude and longitude coordinates and translating that to an address.
Updates in the service include:
- Requests no longer require a Maps API key
- Google Maps Premier customers must sign their requests
- V2 of the web service is now deprecated – can still be used and is still supported
A word of warning, if you do use this service to geocode addresses, you can only use those geocoded values with the Google Maps API – you can’t use it with other services such as Bing Maps.
