How to get data of the object of custom selected area on Google maps

[Sergey Aleksandrov]

Hi, 

My task is to get house numbers and corresponding street name. 

But this list should be generated from custom selected area of the map. So the first question is there a possibility to make a free selection on the map? 

The second one is how to get information about all object in the selected area? 

I have found such type of reverse Geo-codding for a point: 

http://maps.googleapis.com/maps/api/geocode/json?latlng=47.839873,35.147742&sensor=true

where 47.839873,35.147742 - are the coordinates of a point. 

Returned data for the request: 

 "results" : [
      {
         "address_components" : [
            {
               "long_name" : "23",
               "short_name" : "23",
               "types" : [ "street_number" ]
            },
            {
               "long_name" : "Oleksandra Matrosova street",
               "short_name" : "Oleksandra Matrosova street",
               "types" : [ "route" ]
            },
            {
               "long_name" : "Ordzhonikidzevs'kyi district",
               "short_name" : "Ordzhonikidzevs'kyi district",
               "types" : [ "sublocality", "political" ]
            },

and so on. (if you send the request shown above, you will see complete data). 

Please help to find the solution for "free map area selection" and for "how to reverse geo-code free area". Thank you!
