Google Map - UK Geocoding

Sep14

Written by:Steve White
Thursday, September 14, 2006 

The Google Maps API is missing one important element for the UK - the ability to type in an address and then find that address on the map. This is known as geocoding: turning an address into map co-ordinates. So until there is a reliable geocoder for the UK in the Google Maps API I had to turn elsewhere.
I registered the application on the Yahoo Geocoding service: http://developer.yahoo.com/maps/rest/V1/geocode.html and started playing around.

I sent the AJAX request via a server side proxy to overcome the security of cross domain XMLHttp calls. I then processed the XML on the server side and returned XML back to the Javascript function to be parse.

If we get back a valid UK point from Yahoo, then the map automatically centers on that point and data is loaded depending on the bounds of the map. If not, we just return an alert to the client.

All's working well so far, but looking forward to the Google version.

Re: Google Map - UK Geocoding

You may already know about this but google have recently added the functionality that you are talking about. I wrote a post on it recently that has a link or two that you might be interested in. (http://paulbrackenridge.com/2007/07/17/google-map-geocoding-now-for-the-uk/).

Re: Google Map - UK Geocoding

Thanks for letting me know Paul. A member of the Google API Group also let me know about this. It's great news for the UK as a lot of people have been waiting for this. I've included the Local UK search on my map using the AJAX Search API and will eventually use the Google UK Geocoding service.
