[Talk-ca] [Imports] [Talk-us] TIGER considered harmful

[Dan Putler]

Hi Kate,

How have the address points been obtained? From OSM users? The Census
Bureau has collected and created a national data set of them in
preparation for the 2010 Census, but for non-disclosure reasons, they
have no intention of releasing them to the public. The next possible
public source of this type of information would be based on county
assessor parcel data, but that is limited to those counties that have
released their parcel data (although, counties that have released
address ranged centerline street data also tend to be the same ones who
released their parcel data).
