#Heroku buildpack: GeoDjango
This is a Heroku buildpack for GeoDjango apps. It extends the original Python buildpack by adding GEOS, Proj.4 and GDAL, per the GeoDjango installation instructions.
This is a Heroku buildpack for Python apps.
##Configuration
You need to set two Django settings in order for GEOS and GDAL to work properly.
settings.py
from os import environ
GEOS_LIBRARY_PATH = environ.get('GEOS_LIBRARY_PATH')
GDAL_LIBRARY_PATH = environ.get('GDAL_LIBRARY_PATH')##Usage
The buildpack will detect your app as Python if it has the file requirements.txt in the root.
It will use Pip to install your dependencies, vendoring a copy of the Python runtime into your slug.
$ heroku create --stack cedar --buildpack http://github.com/dulaccc/heroku-buildpack-geodjango/
$ git push heroku master
