The OSMqa project wants to provide a simple Quality Assurance system, so that people can work together on improving OSM data without going twice to the same already-mapped place.

Requirements

On a debian-based system (package versions may differ): sudo apt-get install postgis postgresql-8.4-postgis libapache2-mod-fcgid libapache2-mod-python sudo apt-get install libapache2-mod-wsgi cgi-mapserver mapserver-bin python2.6 python2.6-dev sudo apt-get install libgeos-3.1.0 python-setuptools gcc-4.3 libpq-dev sudo a2enmod expires headers fcgid python sudo easy_install Shapely psycopg2

Before creating the database, I suggest you have a look at the docs/OPTIMIZATIONS.txt file. This should help save a lot of your precious time.

Installation

svn checkout http://osmqa.googlecode.com/svn/trunk/ osmqa cd osmqa

SQL

We first create the database and spatially enable it: sudo su postgres createdb -E UTF-8 osmqa createlang plpgsql osmqa Depending on your postgresql version, you should either : psql -d osmqa -f /usr/share/postgresql-8.3-postgis/lwpostgis.sql psql -d osmqa -f /usr/share/postgresql-8.3-postgis/spatial_ref_sys.sql or: psql -d osmqa -f /usr/share/postgresql/8.4/contrib/postgis.sql psql -d osmqa -f /usr/share/postgresql/8.4/contrib/spatial_ref_sys.sql

Then, go to http://openlayers.org/dev/examples/vector-formats.html, select WKT format, input proj = epsg:4326, output proj = spherical mercator, and draw a polygon surrounding the area you want to survey, copy the generated WKT string and paste it into scripts/area.py cd scripts python generate_tiles.py This generates a (big) sql/generated/tiles.sql file

Next, we want to use shorelines to filter out vector tiles which do not intersect lands. This step is optional. wget http://tile.openstreetmap.org/processed_p.tar.bz2 tar xvjf processed_p.tar.bz2

We then convert the resulting shapefile into SQL: shp2pgsql -s 900913 -g geometry -I processed_p.shp processed_p > /tmp/processed_p.sql

Finally, SQL files are inserted: sudo su postgres cat /tmp/processed_p.sql sql/osmqa.sql sql/generated/tiles.sql | psql -d osmqa

App install

Bootstrap your project: python bootstrap.py --version 1.5.2 --distribute Create your config file: cp buildout_sample.cfg buildout_myconfig.cfg Edit the [vars] section of buildout_myconfig.cfg to match your setup (database, servername ...)

Install your project and its dependencies: buildout/bin/buildout -c buildout_myconfig.cfg

If necessary, create your db user (we assume "www-data" here): sudo su postgres createuser -p 5432 -S -D -R -I -P "www-data"

Grant rights to your db user: psql -d osmqa -f sql/grants.sql exit

Optionally, we want to delete tiles above the oceans: python scripts/intersectsland.py (this can take a long time)

Quick test to check everything's ok : ./buildout/bin/paster serve --reload myproject_dev.ini Open http://localhost:5000/tiles?limit=1 You should see a nice GeoJSON string !

Apache configuration

A very simple apache virtual host config file has been created during project setup (apache/osmqa.conf.vhost). You can choose to use it (or not):

cd /etc/apache2/sites-available/ sudo ln -s $yourdir/apache/osmqa.conf.vhost osmqa (where $yourdir is the place you have installed the project) sudo a2ensite osmqa sudo /etc/init.d/apache2 restart

... and you're done with it !
