      Highly accurate digital roadmaps with detailed house-numbering data
are produced by Etak, Inc., in Menlo Park, CA.  Etak makes these for their
automatic vehicle navigation displays, but they are available for other
purposes, and there are sources of PC-based software capable of using them.
For example, you can feed in a mailing list and see all the addresses
appear as dots on a map.  The system can pan and zoom rapidly over the
entire map database.  Map databases are available for most East and West
Coast U.S. metropolitan areas, out to the outer suburbs, plus various
other locations.  Much of Germany is available, as is the Tokyo area.
Prices for a single metropolitan area are quite reasonable.

      This is high-quality data, with the primary sources being USGS maps
and aerial photographs.  It's not just rehashed commercial roadmap data.
