geocoding

In Objective-C this code works fine to plot an address and it finds the longitude and latitude coordinates: NSString *address = @"1 Infinite Loop, CA, USA"; CLGeocoder *geocoder = [[CLGeocoder alloc] init]; [geocoder geocodeAddressString:address completionHandler:^(NSArray* placemarks, NSError* error){ // Check for returned placemarks if (placemarks && placemarks.count > 0) { CLPlacemark *topResult = [placemarks objectAtIndex:0]; // Create a MLPlacemark and add it to the map view MKPlacemark *placemark = [[MKPlacemark alloc] initWithPlacemark:topResult]; [self.mapView addAnnotation:placemark];

I want to use geo coding services in my site which are the APIs available for this, Java based solutions will be preferred and I want to use this in a commercial project so please suggest appropriate options i.e. APIs which can be used in such projects freely..

Is there any standard format to supply the address string to Google GeoCoding API to get the most accurate results on map. For Eg. following query not giving correct result. http://maps.googleapis.com/maps/api/geocode/xml?address=bloom,Bloomfield,CT,06002,USA&sensor=false Thanks Mandeep I believe the suggested format is: House Number, Street Direction, Street Name, Street Suffix, City, State, Zip, Country The results get less specific the less information you can supply, obviously. In your sample, the geocoder is searching for a street named 'bloom', of which there are similar matches in OH

I want to present my users with a text box wherein they can type in their address. As they type their address, I want to provide the users with suggestions/predictions of what address they are trying to type. I'm also concerned about the relevance of this address (e.g. that the address is not an address halfway across the world). Is this possible? I'm using jQuery. You can use Google Places API to have an autocomplete for address. When address is selected, address_components field contains structured address data (e.g. street, city, country) and could be easily converted into separate fields.
