Use US Censor (Tiger) address database for missing OpenStreetMap US addresses

[biodranik]

In the ideal world, all houses will be in OSM and will have their addresses. But in reality, it's often needed to navigate to some address that is not (yet) in OSM.

A good test case from the documentation for testing the search in the U.S.:

Who is familiar with Tiger (from Nominatim, but doesn’t matter)?
I made a quick check of data source, some entries:

802;800;even;Central Ave;Berkeley;WV;25404;LINESTRING(-77.950436 39.463301,-77.950452 39.463250,-77.950607 39.462734,-77.950622 39.462683)
I expect 2 house numbers 800 and 802, but have 4 points in LINESTRING.

698;600;all;Boston St;Berkeley;WV;25401;LINESTRING(-77.970484 39.464604,-77.970540 39.464630)
I expect a wide range of addresses 600 - 698, but have only 2 points

So the questions are:

• Should I make some manual interpolation to get the exact house number <-> exact (lat, lon) point, and how?
• Or I just should treat this data as OSM addr:interpolation/odd/even/all and don’t think at all?

@Zverik ?

Or there is some other Tiger data exist with more precise point addresses? :)

Possibly the National Address Database?

Isnt this done with the newest update?
