How to get the equivalent of the accuracy in Google Map Geocoder V3

Question

I want to get geocode from google, and I used to do it with the V2 of the API. Google send in the json a pretty good information, the accuracy, reference here : http://code.google.com/intl/fr-FR/apis/maps/documentation/javascript/v2/reference.html#GGeoAddressAccuracy

In V3, Google doesn't seem to send me exactly the same information. There is the array "adresse_component", which seem bigger if the accuracy is better, but not exactly. For example, I have a request accuracy to the street number, the array is of size 8. Another query is accuracy to the route, so less accuracy, but the array is still of size 8, as there is a row 'sublocality', which not appear in the first case.

Ok, for a result, Google send a data 'types', which have the 'best' accuracy. This types are here : http://code.google.com/intl/fr-FR/apis/maps/documentation/geocoding/#Types But, there is no real order, and if I wan't the result better than postal_code, I have no clue to how to do that.

So, how can I get this equivalent of the V2 accuracy, whithout some dumb and horrible code ?

Answer 1

Well, there is the location type, which is not so bad :

location_type stores additional data about the specified location. The following values are currently supported:

"ROOFTOP" indicates that the returned result is a precise geocode for which we have location information accurate down to street address precision.

"RANGE_INTERPOLATED" indicates that the returned result reflects an approximation (usually on a road) interpolated between two precise points (such as intersections). Interpolated results are generally returned when rooftop geocodes are unavailable for a street address.

"GEOMETRIC_CENTER" indicates that the returned result is the geometric center of a result such as a polyline (for example, a street) or polygon (region)."

"APPROXIMATE" indicates that the returned result is approximate.

I test if the location_type is different of approximate, and it gives some good results.
