On the contrary, any use in a serious navigation system fails to meet
user expectation if not using accurate addr:housenumber. The #1 or #2
complaint in Skobbler's free US Smartphone navigation app is that the
location is .25 mile, 9 houses, or 1/2 block from the real location. It is
extremely useful and impressive to be delivered to the exact street address.
I would be surprised if there is any realistic way to crowdsource 99% of
addr:housenumber in the US. It's mindnumbing work, dangerous in some areas
where pedestrians and bikes are not safe.
the Tiger interpolated house number data is out there. it's a little erratic
(it places my house about 1/4 mile south of where it really is), but
seemingly the start point for the major map sources in the US.
