Heroku buildpack: Geospatial Libraries

This is a Heroku buildpack that vendors main geo/gis libraries like geos, proj and gdal.

We forked this from cyberdelia/heroku-geo-buildpack since it's associated S3 bucket didn't have support for the heroku-18 stack yet, and we'd like to use github's releases to make the libs available instead of an AWS S3 bucket.

⚠️ Make sure your heroku stack matches the releases' binaries (heroku-18).


Example usage:

$ heroku buildpacks:set https://github.com/CheesecakeLabs/heroku-geo-buildpack.git
$ heroku buildpacks:add heroku/python

Run heroku buildpacks to make sure that heroku-geo-buildpack is added before the language buildpacks.

$ heroku buildpacks

1. https://github.com/CheesecakeLabs/heroku-geo-buildpack.git
2. heroku/python


Binaries for geos, gdal and proj are build on the appropriate heroku stack image using Docker & attached to a release. To update or rebuild these:

  • Set the versions and stack environment in support/docker-compose.yml
  • If updating the stack, also update it in support/Dockerfile
  • Make sure you've deleted any cached heroku docker images
  • Build with cd support && docker-compose run geo-builder
  • Wait 20 minutes, and check the contents of your /tmp/ folder for any .tgz files. Those files must be uploaded with a manifest.<lib> indicating the correct lib version to your release.


On Django Shell:

>>> from django.contrib.gis import gdal
