Simple Tiles

GeoConcerns requires the image generation library Simple Tiles.

Mac OS X:

  • Install via Homebrew: brew install simple-tiles


  • Install dependencies:
  • Compile:
  $ git clone
  $ cd simple-tiles
  $ ./configure
  $ make && make install


Create and run a new GeoConcerns application from a template:

$ rails new app-name -m
$ cd app-name
$ rake hydra:server

Add GeoConcerns models to an existing CurationConcerns application:

  1. Add gem 'geo_concerns' to your Gemfile.
  2. bundle install
  3. rails generate curation_concerns:install
  4. rails generate geo_concerns:install -f


  1. bundle install
  2. rake engine_cart:generate
  3. rake geo_concerns:dev_servers


  1. rake ci

To run tests separately:

$ rake geo_concerns:test_servers

Then, in another terminal window:

$ rake spec

To run a specific test:

rspec spec/path/to/your_spec.rb:linenumber
