OpenStreetMap

Using excellent instructions from http://bostongis.com/ In particular, the Almost idiot's guide...

First, get the data from CloudMade for California and Oregon, or if you have LOTS of time and space get the whole planet.

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 and spatially enable it and add hstore.

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;

# The western US - I had to increase the node cache size
osm2pgsql us-west-latest.osm.pbf -d osm -U osm -S ~/src/GIS/osm2pgsql/default.style --hstore -C 10000

# The whole planet - I RUN OUT OF MEMORY!! Dang.
osm2pgsql planet-latest.osm -d osm -U osm -S ~/src/GIS/osm2pgsql/default.style --hstore -C 15000

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
