Currently programing C# methods to retrieve the following address information:
Latitude/Longitude based upon postal address
Latitude/Longitude based upon ip address
Postal Address based upon ip address
Postal Address based upon zip/postal code
Anyone know of any geolocation services/api’s I can plug in to that can help with retrieving some of the above? I am based in Europe.
Google provide a great Geocoding API. It supports JSON and XML.
Example: http://maps.google.com/maps/api/geocode/xml?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&sensor=true
The free version is limited to 2,500 geolocation requests per day.
