Hi
I'm proposing OpenStreetMap which is of variable size up to >250 GB
XML Data for whole world.
It's downloadable from CloudMade.com or Geofabrik.de and can be
imported into PostgreSQL using osm2pgsql.
It's a key/value schema literally of the real world. I'm using hstore
option of osm2pgsql and hstore index is based on GIST.
I'm running a database instance called "PostGIS Terminal" which is a
daily extract of Switzerland:
http://labs.geometa.info/postgisterminal/?xapi=node%5Bname%3DHochschule%20Rapperswil%5D
This is a typical query which extracts 'real' highways (being of
geometry linestring, aka line/way) with a speed limit >= 100 km/h:
SELECT ST_AsText(way) geom
FROM osm_line
WHERE tags @> '"highway"=>"motorway"'
AND coalesce(substring((tags->'maxspeed') FROM E'[0-9]+')::int,0) >= 100
Yours, Stefan
