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 buildpack assumes your PostGIS server lives outside the Heroku stack, though we'd love to see it forked to handle any setup for Heroku's Postgres services.


Example usage:

$ heroku create --stack cedar --buildpack http://github.com/cirlabs/heroku-buildpack-geodjango/

$ git push heroku master
-----> Heroku receiving push

-----> Installing ...
   Proj.4 installed
-----> Fetching and installing GDAL 1.8.1
-----> Installing ...
   GDAL installed
-----> Preparing virtualenv version 1.7
... etc.


All libraries are stored in /app/.github.

IMPORTANT: You will need to set two Django settings in order for GEOS and GDAL to work properly!

GEOS_LIBRARY_PATH = '/app/.geodjango/geos/lib/libgeos_c.so'

GDAL_LIBRARY_PATH = '/app/.geodjango/gdal/lib/libgdal.so'

and run heroku config:add LD_LIBRARY_PATH='.heroku/vendor/lib:.geodjango/proj4/lib' to allow the proj4 library to be loaded
