PostGIS adds geographic object support to PostgreSQL, turning it into a spatial database. GEOS, PROJ.4 and GDAL should be installed prior to building PostGIS. You might also need additional libraries, see PostGIS requirements.
The psycopg2 module is required for use as the database adapter when using GeoDjango with PostGIS.
On Debian/Ubuntu, you are advised to install the following packages: postgresql-x.x, postgresql-x.x-postgis, postgresql-server-dev-x.x, python-psycopg2 (x.x matching the PostgreSQL version you want to install). Please also consult platform-specific instructions if you are on Mac OS X or Windows.
First download the source archive, and extract:
$ wget http://download.osgeo.org/postgis/source/postgis-2.1.5.tar.gz $ tar xzf postgis-2.1.5.tar.gz $ cd postgis-2.1.5
Next, configure, make and install PostGIS:
Finally, make and install:
$ make $ sudo make install $ cd ..
GeoDjango does not automatically create a spatial database. Please consult the section on Creating a spatial database for more information.
PostGIS 2 includes an extension for Postgres 9.1+ that can be used to enable spatial functionality:
$ createdb <db name> $ psql <db name> > CREATE EXTENSION postgis;
The database user must be a superuser in order to run
CREATE EXTENSION postgis;.
GeoDjango does not currently leverage any PostGIS topology functionality. If you plan to use those features at some point, you can also install the
postgis_topology extension by issuing
CREATE EXTENSION postgis command is now automatically run during the
migrate process. You can still create it manually if you wish.
To administer the database, you can either use the pgAdmin III program (
geodjango spatial database and user, the following may be executed from the SQL Shell as the
postgres# CREATE USER geodjango PASSWORD 'my_passwd'; postgres# CREATE DATABASE geodjango OWNER geodjango;
