Openstreetsmap Mapnik (ref)

git clone git://github.com/openstreetmap/mapnik-stylesheets.git

Then…

cd mapnik-stylesheets

Download the mapping data for the country of your choice (or everything from planet.openstreetmap.org) (ref)

wget http://download.geofabrik.de/openstreetmap/australia-oceania/australia.osm.pbf
wget http://download.geofabrik.de/openstreetmap/australia-oceania/new-zealand.osm.pbf

Download the additional data-files to be used when generating maps (ref):

wget http://tile.openstreetmap.org/world_boundaries-spherical.tgz # (50 MB)
wget http://tile.openstreetmap.org/processed_p.tar.bz2 # (349 MB)
wget http://tile.openstreetmap.org/shoreline_300.tar.bz2 # (44 MB)
wget http://www.naturalearthdata.com/http//www.naturalearthdata.com/download/10m/cultural/ne_10m_populated_places.zip
wget http://www.naturalearthdata.com/http//www.naturalearthdata.com/download/110m/cultural/ne_110m_admin_0_boundary_lines_land.zip # (39 KB)

Extract the files using the following commands;

cd ~/mapnik-stylesheets # or whatever directory you put the project in
tar xzf world_boundaries-spherical.tgz
tar xjf processed_p.tar.bz2 -C world_boundaries
tar xjf shoreline_300.tar.bz2 -C world_boundaries
unzip ne_110m_admin_0_boundary_lines_land.zip -d world_boundaries
unzip ne_10m_populated_places.zip -d world_boundaries
cd world_boundaries
ln -s ne_110m_admin_0_boundary_lines_land.shp 110m_admin_0_boundary_lines_land.shp
ln -s ne_110m_admin_0_boundary_lines_land.dbf 110m_admin_0_boundary_lines_land.dbf
cd ../

Get the default style

wget http://svn.openstreetmap.org/applications/utils/export/osm2pgsql/default.style

Postgres / PostGIS

Configure / finish setting up PostGIS DB (ref)

sudo apt-get install postgresql-9.1-postgis postgresql-contrib-9.1
sudo -u postgres -i -H
createuser -SdR gisuser
createdb -E UTF8 -O gisuser gis
createlang plpgsql gis
psql -d gis -f /usr/share/postgresql/9.1/contrib/postgis-1.5/postgis.sql
  # to populate the table spatial_ref_sys (mandatory for use with osm2pgsql):
  psql -d gis -f /usr/share/postgresql/9.1/contrib/postgis-1.5/spatial_ref_sys.sql

# common for all three
psql gis -c "ALTER TABLE geometry_columns OWNER TO gisuser"
psql gis -c "ALTER TABLE spatial_ref_sys OWNER TO gisuser"
exit

To enable easy database login by user gisuser you must change some lines in one of the database configuration files.

sudo pico /etc/postgresql/9.1/main/pg_hba.conf

Near to the bottom of the file you will find these lines:

local   all         all                               ident
host    all         all         127.0.0.1/32          md5

Change the words ident and md5 each to trust and close the editor. Now reload the database configuration:

sudo /etc/init.d/postgresql reload

For a short test, login to the database by using the previously created database user gisuser:

psql gis gisuser

Type \d to see a list with the two tables which we have created some minutes ago (geometry_columns and spatial_ref_sys), then logout with: \q

Tuning the PostGIS database (ref)

edit /etc/postgresql/9.1/main/postgresql.conf in four places. These changes help with the large quantities of data that we are using.

shared_buffers = 128MB
checkpoint_segments = 20
maintenance_work_mem = 256MB # 256000 for 8.1 and earlier 
autovacuum = off

Edit kernel parameter shmmax to increase maximum size of shared memory.

sudo sysctl -w kernel.shmmax=268435456
sudo sysctl -p /etc/sysctl.conf

Restart postgres to enable the changes

sudo /etc/init.d/postgresql restart

It should restart as above.

* Restarting PostgreSQL 8.4 database server
  ...done.

Import the OSM file for your country (this will take some time)

sudo -u postgres osm2pgsql -d gis -S default.style --slim -m australia.osm.pbf [file2 ...]

Configure Mapnik Style files

./generate_xml.py --host localhost --user gisuser --dbname gis --symbols ./symbols/ --world_boundaries ./world_boundaries/ --accept-none

mod_tile

See: http://switch2osm.org/serving-tiles/building-a-tile-server-from-packages/

~~http://www.kelvinism.com/howtos/revised-mod_tile-howto/~~

sudo apt-get install libagg-dev svn co http://svn.openstreetmap.org/applications/utils/mod_tile cd mod_tile make
make install

Errors about APXS2 can be cured by installing:

apt-get install apache2-threaded-dev

Then create a load file for the apache module

pico /etc/apache2/mods-available/tile.load

Insert the following:

LoadModule tile_module /usr/lib/apache2/modules/mod_tile.so

Configure mod_tile / renderd

http://wiki.openstreetmap.org/wiki/HowTo_mod_tile

ln -s /home/victor/osm/renderd /var/lib/mod_tile

Download the fonts from http://dejavu.sourceforge.net/wiki/index.php/Download and extract the font files (*.ttf) to /usr/local/lib/mapnik/fonts dir

wget http://downloads.sourceforge.net/project/dejavu/dejavu/2.33/dejavu-fonts-ttf-2.33.tar.bz2?r=http%3A%2F%2Fdejavu-fonts.org%2Fwiki%2Findex.php%3Ftitle%3DDownload&ts=1322024644&use_mirror=internode
mv dejavu-fonts-ttf-2.33.tar.bz2\?r\=http\:%2F%2Fdejavu-fonts.org%2Fwiki%2Findex.php\?title\=Download dejavu-fonts.tar.bz2
tar xvf dejavu-fonts.tar.bz2
mv dejavu-fonts-ttf-2.33 /usr/local/lib/mapnik/fonts

Edit /etc/renderd.conf

Create /etc/init.d/renderd with the following contents:

#!/bin/sh -e
# Renderd startup script
#chkconfig: 2345 80 05
#description: Renderd

# Define some variables
# Name of app ( abc / def / blah / etc )
APP=renderd
# Name of the user to run as

# Location of application's bin directory
BIN_DIR=/home/www/gis/mod_tile
PIDFILE=/var/run/renderd/$APP.pid

case "$1" in

#    echo "Stopping $APP"
#    echo "$APP stopped successfully"
    ;;
   # Restart command
   restart)
        $0 stop
        sleep 5
        $0 start
        ;;
  *)
    echo "Usage: /etc/init.d/$APP {start|restart|stop}"
    exit 1
