[Geocoding] Reverse geocoding functionalities

[Gergely Hanti]

Hello,

As far as I know the reverse geocoding looks for the nearest place in the
database, so it also gives result for "unmapped" territories. For example if
I use an extract of a city, the reverse geocoding will produce an address
inside that city for coordinates anywhere in the world.

How could I check the validity of the result?
Is it possible to get the coordinates of the result (or even the
geographical distance from the input coordinates)?
Can the country be determined for a position outside the "mapped"
territories? (Maybe somebody has a method for using the data of the
import_worldboundaries.sql script)

Thanks in advance!
