I've been in contact with VITA, the agency responsible for GIS for the state of Virginia, USA. They are interested in OSM utilizing their road centerline data. VITA coordinates with all the localities in Virginia to obtain this information, though most of it is sourced from the Virginia Base Mapping Program (VBMP), which updates orthoimagery of Virginia every few years with resolution between 6-inches and 2-feet. This is the same data that is used for E911 in Virginia. From what I've seen thus far this data is very good, and certainly much better than the TIGER data.
I'm totally new to importing, so I first wanted to see if anyone else is interested in this project, though I am willing to take the time to learn the process myself. Is the process used for importing the Canadian database [1] the best method for doing this? Of course I'm all for the standard rules of imports, don't destroy previous work, okay to blow away TIGER data in areas that haven't been touched by other mappers, but conflate in other areas, etc. I'll be taking this very slowly. Unfortunately the statewide RCL database doesn't contain address ranges, though some localities does provide that information. For example, Fairfax County provides RCL data in the public domain that includes this information. This of course leads me to believe that it is best to import the data on a locality by locality basis, if not even smaller regions. Again, don't think I'm about to do a massive import all of a sudden. Right now I'm looking for interest and feedback, and will begin to flesh out a wiki article about this import.
