how can we export some data useful in GIS except WMS.Because each GIS user prefer SHP file so he can do what ever he wants with it?
i m confused!!
Cloudmade and Geofabrik provide OSM data in shapefiles to download for various parts of the world. See http://downloads.cloudmade.com and http://download.geofabrik.de/osm/
Or its possible to convert OSM data to shapefiles, some links to software on this page: http://wiki.openstreetmap.org/wiki/Shapefiles
A very flexible way is to import data into a local PostGIS database with osm2pgsql and publish the osm_point, osm_line and osm_polygon tables as WFS feature types with Geoserver. Geoserver offers an vendor option to output WFS as zipped shapefiles.
Of course, if you have OSM data in a local PostGIS database you do not need WFS really. Most open source GIS softwares can query data directly from PostGIS.
