Using excellent instructions from http://bostongis.com/ In particular, the Almost idiot's guide...
First, get the data from CloudMade for California and Oregon
mkdir /green/GISData/OSM && cd /green/GISData/OSM wget http://downloads.cloudmade.com/americas/northern_america/united_states/california/california.osm.bz2 wget http://downloads.cloudmade.com/americas/northern_america/united_states/oregon/oregon.osm.bz2
Create a lovely Postgis database
createdb -U postgres osm -W -T template_postgis
My installed-from-source Postgis did not have hstore.sql so I built it:
cd ~/src/GIS/postgresql-9.0.6/contrib/hstore USE_PGXS=1 make && sudo USE_PGXS=1 make install cd /usr/local/pgsql/share/contrib
Do this each time you create a database a: add hstore support to the database
psql -U postgres osm < hstore.sql
Build osm2pgsql
No need for any special configuration options, just build and install!
sudo apt-get install libxml2-dev libbz2-dev cd ~/src/GIS git clone https://github.com/openstreetmap/osm2pgsql.git cd osm2pgsql ./autogen.sh ./configure sed -i 's/-g -O2/-O2 -march=native -fomit-frame-pointer/' Makefile make sudo make install
Using osm2pgsql
# bellman osm2pgsql oregon.osm.bz2 -d osm -U postgres \ -S /green/bwilson/src/GIS/osm2pgsql/default.style --hstore osm2pgsql california.osm.bz2 --append -d osm -U postgres \ -S /green/bwilson/src/GIS/osm2pgsql/default.style --hstore
# dart createdb -U postgres osm createuser -U postgres osm psql -U postgres osm CREATE EXTENSION hstore; CREATE EXTENSION postgis; # Just Oregon - I had to increase the node cache size on Dart where I am loading US West not just Oregon. -C 3000 osm2pgsql us-west-latest.osm.pbf -d osm -U osm -S /home/AGI/bwilson/src/GIS/osm2pgsql/default.style --hstore -C 3000 # The whole planet - You unzipped it Brian! Don't uncompress first - it's a waste of time. osm2pgsql planet-latest.osm -d osm -U osm -S ~/src/GIS/osm2pgsql/default.style --hstore -C 5000
On my little server Bellman, it took 628 seconds to load the Oregon data and it took 3302 seconds to load California. Conclusion: California is much bigger, in fact there is probably room for me there in Nevada county.
I just loaded Oregon data onto my much snazzier server at work and it took 183 seconds.
Nice to have some data in my PostGIS server.
Now I need to get it showing up in Geoserver
