OCitySMap installation instructions
===================================

These instructions refer to software dependencies by using Ubuntu
Lucid (10.04) package names. Minor adaptations might be needed for
other distributions or for the precise Debian or Ubuntu release you
are using. They have been tested on several x86_64 hosts.

 1. Installation of PostgreSQL and PostGIS

    sudo aptitude install postgresql postgresql-contrib

 2. Creation of a new PostgreSQL user

    sudo -u postgres createuser -P -S -D -R maposmatic

    Enter the password twice (we use later 'ereiamjh' as example
    password).

 3. Creation of the database

    sudo -u postgres createdb -E UTF8 -O maposmatic maposmatic

    (see http://wiki.openstreetmap.org/wiki/Mapnik/PostGIS)

    You can now try to connect to the database, using:

    psql -h localhost -U maposmatic maposmatic

    If it doesn't work, fix your configuration.

 4. Enable PostGIS on the database

    PostGIS is in fact a set of functions and datatypes for
    PostgreSQL, and every PostgreSQL database needing these features
    must be initialized as follows. We do this initialization of the
    database with superuser privileges, and then later fix the table
    owners so that our normal user can use the database.

    a. Enable the plpgsql language on the maposmatic database

    sudo -u postgres createlang plpgsql maposmatic

    b. Download postgis 1.5.1

    sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable

    sudo aptitude update
    sudo aptitude dist-upgrade # Or safe-upgrade if you prefer

    sudo aptitude install postgresql-8.4-postgis

    c. Install PostGIS support in Postgres

    sudo -u postgres \
         psql \
              -f /usr/share/postgresql/8.4/contrib/postgis-1.5/postgis.sql \
              -d maposmatic

    Provide comments (Optional):

    sudo -u postgres \
         psql \
              -f /usr/share/postgresql/8.4/contrib/postgis_comments.sql \
              -d maposmatic

    d. Add the list of spatial referential systems

    sudo -u postgres \
         psql \
              -f /usr/share/postgresql/8.4/contrib/postgis-1.5/spatial_ref_sys.sql \
              -d maposmatic

    e. Add the intarray extension for diff files support (osc)

    sudo -u postgres \
         psql \
              -f /usr/share/postgresql/8.4/contrib/_int.sql \
              -d maposmatic

    f. Change the owner of the new tables to maposmatic

    echo "ALTER TABLE geometry_columns OWNER TO maposmatic;
          ALTER TABLE spatial_ref_sys OWNER TO maposmatic;" | \
    sudo -u postgres psql -d maposmatic

 5. Installation of osm2pgsql

    osm2pgsql is the tool that takes OSM data as input, and creates a
    PostGIS database from it. At the time of the writing of this
    document, the osm2pgsql packaged in Debian/Ubuntu is not recent
    enough, so we grab a fresh version from SVN (we used revision
    17318).

    a. If needed, install SVN

    sudo aptitude install subversion

    b. Grab osm2pgsql code

    svn co http://svn.openstreetmap.org/applications/utils/export/osm2pgsql/
    # Tested revision: r22641

    c. Install the build dependencies

    sudo apt-get build-dep osm2pgsql

    d. Compile

    cd osm2pgsql
    ./autogen.sh
    ./configure # with --prefix=.... as needed
    make

    e. Install

    Provided you supplied the correct --prefix=... option, just enter:

    make install

 6. Download the OSM data

    We give the example for Luxembourg.

    wget http://download.geofabrik.de/osm/europe/luxembourg.osm.bz2

 7. Import the OSM data

    osm2pgsql -s -c -d maposmatic -m -U maposmatic -W \
              -H localhost luxembourg.osm.bz2

    If you have a lot of RAM, remove '-s', it will make the import
    faster. If you miss RAM (and have a lot of time available) you can
    also use the '-C' option together with '-s'. (See osm2pgsql -h).

    If you want to add other OSM DB files, replace the '-c' option
    with a '-a' option in the subsequent files you are adding: if you
    keep the '-c' option, it will erase any previous GIS data you may
    have. For example:

    osm2pgsql -s -a -d maposmatic -m -U maposmatic -W \
              -H localhost ile-de-france.osm.bz2


 8. Install Mapnik

    We need Mapnik 0.7.1, which is not yet available in stable
    Debian/Ubuntu, so we need to compile it from source.

    a. Install the dependencies

    sudo apt-get build-dep python-mapnik

    b. Download Mapnik

    wget http://download.berlios.de/mapnik/mapnik-0.7.1.tar.bz2

    c. Compile and install Mapnik

    tar xvjf mapnik-0.7.1.tar.bz2
    cd mapnik-0.7.1

    python scons/scons.py configure INPUT_PLUGINS=all \
      OPTIMIZATION=3 SYSTEM_FONTS=/usr/share/fonts/

    (You can also path PREFIX=... and PYTHON_PREFIX=.... if you don't
    want a system-wide installation)

    python scons/scons.py

    python scons/scons.py install

    d. Check the installation

    Run a Python interpreter, and run "import mapnik". If it doesn't
    work and you didn't do a system-wide installation of Mapnik, don't
    forget to set the PYTHONPATH and LD_LIBRARY_PATH environment
    variables.

10. Install Mapnik-OSM

    Mapnik-OSM is the set of files that tell Mapnik how to render
    OpenStreetMap maps.

    a. Download

    svn co http://svn.openstreetmap.org/applications/rendering/mapnik \
        mapnik-osm
    # Tested revision: r22641

    b. Installation of static data

    In addition to the OpenStreetMap data, some other static data are
    used to render the maps (world boundaries, etc.)

    cd mapnik-osm
    sh ./get-coastlines.sh

    c. Enabling unifont

    In order to get correct rendering for Korean, Chineese or Japanese
    character, the unifont font must be used. In order do enable it,
    edit inc/fontset-settings.xml.inc, and uncomment the following
    line :

    	  <Font face_name="unifont Medium" />

    in the book-fonts, bold-fonts and oblique-fonts sections.

    d. Configuration

    python ./generate_xml.py --dbname maposmatic --host 'localhost' \
                             --user maposmatic --port 5432 \
                             --password 'ereiamjh'

11. Installation of OCitySMap

    a. Install Git if needed

    sudo aptitude install git-core git-email

    b. Grab the sources

    git clone git://git.savannah.nongnu.org/maposmatic/ocitysmap.git

    c. Install dependencies

    sudo aptitude install python-psycopg2 python-gdal \
                          python-gtk2 python-cairo \
			  python-shapely

    Note that python-gtk2 is not needed for any graphical interface,
    but because it contains Pango and PangoCairo that we use to render
    text on the map.

    d. Configuration file

    Create a ~/.ocitysmap.conf configuration file, modeled after the
    provided ocitysmap2.conf-template file.

12. Run OCitySMap

    ./ocitysmap2-render -t "Ceci n'est pas Paris" --polygon-osmid=-943886
