INSTALL

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

These instructions refer to software dependencies by using
Debian/Ubuntu package names. Minor adaptations might be needed for
other distributions or for the precise Debian or Ubuntu release you
are using (here respectively Lenny and Intrepid or Jaunty).

 1. Installation of PostgreSQL and PostGIS

    sudo aptitude install postgresql-8.3-postgis postgresql-contrib-8.3

 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. Add the low-level PostGIS infrastructure

    sudo -u postgres \
         psql \
              -f /usr/share/postgresql-8.3-postgis/lwpostgis.sql \
              -d maposmatic

    c. Add the list of spatial referential systems

    sudo -u postgres \
         psql \
              -f /usr/share/postgresql-8.3-postgis/spatial_ref_sys.sql \
              -d maposmatic

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

    sudo -u postgres \
         psql \
              -f /usr/share/postgresql/8.3/contrib/_int.sql \
              -d maposmatic

    e. 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/

    c. Install the build dependencies

    sudo aptitude install build-essential libxml2-dev libgeos-dev \
                          libpq-dev libbz2-dev proj libbz2-dev

    d. Compile

    cd osm2pgsql
    make

    e. Install

    Just copy the osm2pgsql binary somewhere in your PATH or link to
    it like:

    ln -s /path/to/osm2pgsql/osm2pgsql /usr/local/bin/osm2pgsql

 6. Import the Google spatial referential system

    The osm2pgsql tool creates data in the PostGIS database relative
    to the 900913 (Google in leet language) spatial referential
    system. As this system is not included in the default PostGIS
    installation, we must add it manually. It is available in
    osm2pgsql source code.

    psql -h localhost \
         -U maposmatic \
         -f /path/to/osm2pgsql/900913.sql \
         -d maposmatic

 7. Download the OSM data

    We give the example for France.

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

 8. Import the OSM data

    osm2pgsql -S '/path/to/osm2pgsql/default.style' \
              -s -c -d maposmatic -m -U maposmatic -W \
              -H localhost france.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).

 9. Install Mapnik

    We used Mapnik 0.6.1, which was not yet available in stable
    Debian/Ubuntu at the time we set up MapOSMatic, so we compiled it
    from source.

    a. Install the dependencies

    sudo aptitude install \
        libboost-dev libicu-dev libstdc++6-dev python-dev \
        libfreetype6-dev libjpeg62-dev libltdl3-dev libpng12-dev \
        libtiff4-dev libtiffxx0c2 python-imaging proj libcairo2-dev \
        python-cairo-dev libcairomm-1.0-dev libpixman-1-dev \
        libpthread-stubs0-dev ttf-dejavu ttf-dejavu-core \
        ttf-dejavu-extra ttf-unifont libgdal-dev python-gdal \
        postgresql-server-dev-8.3 postgresql-contrib-8.3 libxslt1-dev \
        libxml2-dev

    b. Download Mapnik

    wget http://download.berlios.de/mapnik/mapnik-0.6.1.tar.bz2

    c. Patch Mapnik

    In order to make Mapnik search recursively for fonts in the
    SYSTEM_FONTS directory (see below), we had to patch Mapnik. Note
    that this is because we still use Mapnik 0.6.1. Later versions of
    Mapnik already search recursively for fonts by default. The patch
    to apply follows:

===============================================================================

    d. Compile and install Mapnik

    tar xvjf mapnik-0.6.1.tar.bz2
    cd mapnik-0.6.1

    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

    e. 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

    b. Installation of static data

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

    wget http://tile.openstreetmap.org/world_boundaries-spherical.tgz
    cd /path/to/mapnik-osm/
    tar xzf ~/download/world_boundaries-spherical.tgz

    wget http://tile.openstreetmap.org/processed_p.tar.bz2
    tar xjf ~/download/processed_p.tar.bz2 -C /path/to/mapnik-osm/world_boundaries

    wget http://tile.openstreetmap.org/shoreline_300.tar.bz2
    tar xjf ~/download/shoreline_300.tar.bz2 -C /path/to/mapnik-osm/world_boundaries

    wget http://www.naturalearthdata.com/http//www.naturalearthdata.com/download/10m/cultural/10m-populated-places.zip
    unzip 10m-populated-places.zip -d /path/to/mapnik-osm/world_boundaries

    wget http://www.naturalearthdata.com/http//www.naturalearthdata.com/download/110m/cultural/110m-admin-0-boundary-lines.zip
    unzip 110m-admin-0-boundary-lines.zip -d /path/to/mapnik-osm/world_boundaries

    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

    b. Grab the sources

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

    c. Initialize OCitySMap SQL stuff

    psql -h localhost  \
         -U maposmatic \
         -f /path/to/ocitysmap/ocitysmap-init.sql \
         -d maposmatic

    d. Install dependencies

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

    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.

    e. Configuration file

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

12. Run OCitySMap

    ./ocitysmap-render -f png -c Sanguinet
