You can download polygon's describing geographic areas from http://www.maproom.psu.edu/dcw/. Then if you use those and the osmosis program (http://wiki.openstreetmap.org/index.php/Osmosis) you can extract just the states you want. The planet file (or extracted output from step above) can also be loaded into a Postgresql database using the osm2pgsql (http://svn.openstreetmap.org/applications/utils/export/osm2pgsql/) script and you can query against that. Note that last week's planet file was 77gb once uncompressed so it can take a long time to import into a database if your system isn't that speedy. -Jason Reid _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/dev
