[OSM-talk] The world’s best addressable map

First question: how do you build "the world's best addressable map" ?
Through imports or survey ? Is the timeframe that Martin puts forward fur
surveyed addresses acceptable and feasible ?

As for the imports:

Wouldn't it be great that we would have import tools that can be used by
many groups ? Just as we have great editors for "manual" mapping.
Shouldn't the OSMF (or however) invest in a procedure + tools for import ?

So when a group wants to perform an import, they only have make sure the
license is compatible and the data has enough quality. The process of the
import is already described, the tools ( task managers, data conversion,
some quality checks etc.) are in place. They deliver the data and the
import can start.
I have the impression that right now each group has to take all those
obstacles all by themselves.

Maybe I have a totally wrong perception of the import process. please
correct me if that's the case.
