And then 2)http://www.storm-consultancy.com/bl开发者_运维百科og/development/code-snippets/using-google-maps-api-to-get-latitude-longitude-co-ordinates-from-postcode-or-address/

In this i must have api_key of google.

Now i dont have the api_key.

Is there any another way to get latitude and longitude by pasing address.

Well, if you want to use the Google API then you can get an API key.

There are other resources you can try as well.

You should google for geocoding. Maybe you find something on OpenStreetMap
