As far as I know, the reason this is hard to do is because of lack of complete rooftop geocoding data. The accuracy of the result from the geocoder depends on our data for this location.
If we do not have rooftop data, the geometry result will include "location_type": "RANGE_INTERPOLATED", as opposed to "location_type": "ROOFTOP", If the geocoder doesn't find a street address, the results won't contain a result with type "street_address". In this case, it seems that our geocoder believes this is a valid address and attempts to interpolate the location based on *known* locations along the same road. If you'd like to help improve our data, input the same request on http://maps.google.com/ and press "Report a Problem" (you'll notice that for this address, place the marker with a tooltip saying that the location is approximate :) Cheers Chris On Fri, Nov 5, 2010 at 2:11 PM, [email protected] <[email protected]>wrote: > Hello, > > I am using Google Maps via http request/response: > > http://maps.google.com/maps/api/geocode/json?address=Santa+Fe+900+Ciudad+Aut%C3%B3noma+de+Buenos+Aires,+Argentina&sensor=false > I am having some trouble with invalid address, for example: > I check one street of my city: Santa Fe Av., it range is between 600 and > 5400, but when I check Santa Fe Av. 7000 I get a valid point from Google > Maps. so How can I validate that Santa Fe Av. 7000 does not exist? > > Thank you > salu2... > masch... > > -- > You received this message because you are subscribed to the Google Groups > "Google Maps API V2" group. > To post to this group, send email to [email protected]. > To unsubscribe from this group, send email to > [email protected]<google-maps-api%[email protected]> > . > For more options, visit this group at > http://groups.google.com/group/google-maps-api?hl=en. > -- You received this message because you are subscribed to the Google Groups "Google Maps API V2" group.
