importing osm file into a postgres/postgis database

问题

Im using the tool osm2pgsql to import an osm file into a postgres database using phppgadmin as the administrative tool. i have only downloaded a small town from osm in xml format and im having trouble importing it using the terminal on mac. Im a bit of a noob at this so any help would be greatly appreciated. Ive looked at several articles but none provide the clarity i need in order to fulfill my needs.

Thanks

im getting this error could be something small not sure..

You need to install the postgis extensions into your postgres database. Assuming that you have postgis installed on your machine you need to do something like:

psql <database> < /usr/share/postgresql/8.4/contrib/postgis-1.5/postgis.sql

The exact path to postgis.sql will depend on the distribution you are using and how it has packaged postgis. You may also want/need to install the spatial reference systems table with a command like this:

psql <database> < /usr/share/postgresql/8.4/contrib/postgis-1.5/spatial_ref_sys.sql

This is an example command:

osm2pgsql -c -d your_country -U postgres -W -H localhost -P 5432 -s -k -x -p osm -S default.style ..\your_country.osm.bz2
