Get country from latitude longitude

Question

I would like to know how I can get the country name from latitude & longitude using JavaScript. I am open to use of Google Maps’ JavaScript API. Can I also get city and zip?

Edit: My aim is to fill up the address field automatically, not to display it on a map.

Answer 1

I don't know if it works with google maps, but there is a web service that returns a country code and takes as parameters the lat and long.

Here is an example:
http://api.geonames.org/countryCodeJSON?lat=49.03&lng=10.2&username=demo

Returns a JSON data: {"languages":"de","distance":"0","countryCode":"DE","countryName":"Germany"}

I also found a little description:

The iso country code of any given point.

• Webservice Type: REST
• Url: ws.geonames.org/countryCode?
• Parameters: lat, lng, type, lang, radius (buffer in km for closest country in coastal areas)
• Result: returns the iso country code for the given latitude/longitude

With the parameter type=xml this service returns an xml document with iso country code and country name. The optional parameter lang can be used to specify the language the country name should be in. JSON output is produced with type=JSON

See the docs

Edit: Please note that demo is just a demonstration user and you should create a user account at http://www.geonames.org/login in order to use the service.
