"In an effort to seed the development of Open Source(TM) auto-navigation
software, mapping web sites, and other geographical applications,
I have purchased the
TIGER/Line 1997 data set, and will be reissuing it
on CD under the GPL. This is a complete U.S. map database, with GPS
coordinates, street names, etc.
I am offering one 6-CD set to each of Debian, GNOME, and KDE, and will
consider other worthy non-profit groups with a history of finishing what
they start. They will be able to use this data to develop navigation
applications, etc., under the GPL or LGPL"
specifies this does not include topological data, but
Bruce is looking into other sources of that.
