Heroku buildpack: geo

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

You will use this buildpack with other major buildpack such as Ruby buildpack.

Usage

Example usage:

$ heroku buildpacks:set https://github.com/cyberdelia/heroku-geo-buildpack.git
$ heroku buildpacks:add heroku/ruby

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

Updating

Binaries for geos, gdal and proj are build on the appropriate heroku stack image using Docker & pushed to a public S3 bucket.

To update or rebuild these:

• Set the versions and stack environment in support/docker-compose.yml
• Set the AWS keys to ones with permission to push to the selected S3 bucket
  • These values can be set in support/.env
• If updating the stack, also update it in support/Dockerfile
• Make sure you've deleted any cached heroku docker images
• Build with cd support && sudo docker-compose run
• Wait 20 minutes, and check the contents of the relevant stack folder on S3

Testing

For Geo Django:

>>> from django.contrib.gis import gdal
>>> gdal.HAS_GDAL
True

For rgeo:

>>> require 'rgeo'
>>> RGeo::CoordSys::Proj4.supported?
=> true
>>> RGeo::Geos.supported?
=> true

rails r "require 'rgeo'; puts RGeo::Geos.supported?"
