Google Reverse Geocoder Update

Google Reverse Geocoder Update New! v1.0.2

Reverse Geocoding is the inverse relationship where each geographical coordinate is mapped to the nearest known address. Currently this feature is not directly supported by the Google Map API. But can be done by Nico's Reverse Geocoder for Google Maps API using Google's Directions functionality.

Based on the Original Post by Mapperz


Nico has been keen to add some more useful functionality to the Reverse Geocoder.

Experimental House Number Support

Since v1.0.2. Once the Reverse geocoder is set up experimental house number support is enabled by calling the setExperimentalHouseNumber method as shown in the example.

reversegeocoder.setExperimentalHouseNumber(true);

Important note:
THIS FEATURE IS EXPERIMENTAL AND USES MULTIPLE
GClientGeocoder AND GDirections
REQUESTS WHICH COULD EXCESS THE GOOGLE REQUEST LIMITS.
That's exactly why it is disabled (uncommented) in the full example.
Use it on own risk.
