Why would you assume this? Latitude and longitude describe a precise point (within the tolerance provided by the system). Addresses (especially as defined by the Google Maps API) are imprecise. For example "Georgia" is a valid address, as defined by Google Maps. It is also an ambiguous address. Does it mean the United States state of Georgia or the country in Asia? The API provides for region biasing to disambiguate such addresses. It would be impractical to provide a list of all Lat/Lon pairs for an address. Theoretically that would be an infinitely long list. That is like asking to list every point inside a rectangle. That would also result in an infinitely long list. Reverse geocoding a point into an address is a lot more "fuzzy." Google Maps attempts to provide reasonable results by retuning the "best" address for a given point, along with other addresses within the region surrounding the given point. Unlike geo-points, addresses are finite. There are only a limited number of them within any given region. > So, please let me know how can I get lat/long boundaryies for a pair > of lat/long which will produce same reverse Geo-coded address. Taking a quick look at the Google Maps API I didn't see anything that would directly give you what you want. As I described above I don't even think this makes sense. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
