Simple Tiles

GeoConcerns requires the image generation library Simple Tiles.

Mac OS X:

• Install via Homebrew: brew install simple-tiles

Linux:

• Install dependencies:

  libgdal-dev
  libcairo2-dev
  libpango1.0-dev 
  

• Compile:

  $ git clone git@github.com:propublica/simple-tiles.git
  $ cd simple-tiles
  $ ./configure
  $ make && make install
  

Installation

Create and run a new GeoConcerns application from a template:

$ rails new app-name -m https://raw.githubusercontent.com/projecthydra-labs/geo_concerns/master/template.rb
$ 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

Development

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

Testing

3. 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
