What you are proposing is the best way to provide a compressed
geographic co-ordinate. But for the best 'post code' perhaps it's worth
considering (maybe at the expense of an extra digit) a 'routing index'
would would identify 'official' post codes and hence satisfy those who
need/want 'address based' locations.
In this way you can optionally provide a 'partial' code which gives
accurate location information, or the 'official' code which provides
full address information (registered a central database).
This would also ensure accurate translation as even though you consider
the geolocation codes 'easily converted' I am sure that the process
would be error prone and subject quality of information source.
ie. you might provide an open post code system keeping all camps happy.
