[OSM-talk] Street Addresses

[Dan Putler]

Hi John,

The recently released 2010 TIGER/Line data should have better address 
range information than earlier versions. The US Census Bureau went 
throughout the country with GPS units and collected a national set of 
address points to create its Master Address File (MAF) used implementing 
the 2010 Census. They can't release the MAF for non-disclosure reasons, 
and TIGER/Line data has missing address ranges and "random" address 
ranges (where in some cases they have lengthened or shortened the actual 
ranges) for non-disclosure reasons as well. My guess is importing 2010 
TIGER data for NYC would be a nightmare because of the possibility of 
stepping on user edits in OSM. Given the problems with updating road 
ways, I think the real solution for addresses in OSM is to use address 
points where possible.
