As we can import the OSM data file into the database using osm2pgsql, I want to know that can we optimise that data before importing.

Sure, you can run it through Osmosis with the --tag-filter option to filter out only what you are interested in. You can also modify osm2pgsql's default.style file to import only some tags (but it will not allow you to say "I want only highway=motorway and highway=trunk").
This only works if you are not planning to do incremental updates however. Bye Frederik _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/listinfo/dev
