What is Global Forest Watch?
Global Forest Watch (GFW) is a dynamic online forest monitoring and alert system that empowers people everywhere to better manage forests.
This repository contains the GFW web app.
Developing
The GFW web app rides on Ruby on Rails.
Docker
Place required environment settings in the dev.env
file, and then run:
./gfw.sh develop
GFW should then be accessible at localhost:5000/map, note, it may take around 2 mins to load due to large number of requests.
OS X Yosemite (10.10) Setup
First make sure you have Xcode and Command Line Tools installed.
Next install Homebrew, the OS X package manager:
$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
We recommend managing your Ruby installation through rbenv. It's just an easy way to run multiple Ruby versions for different applications:
$ brew update
$ brew upgrade rbenv ruby-build
$ brew install imagemagick@6
Next clone the gfw repo:
$ git clone https://github.com/Vizzuality/gfw.git
Using rbenv, install and set Ruby 2.4.0 in the main app directory:
$ cd gfw
$ rbenv install 2.4.0
$ rbenv local 2.4.0
Now let's install Ruby on Rails:
$ gem install rails
Aaaaand now use Bundler, a rubygem manager, to install all the gem depenencies for the app:
$ bundle install
Installing front end dependencies:
$ yarn install
Almost there! Final steps are to update your .env
file:

BLOG_HOST=http://blog.globalforestwatch.org
GOOGLE_MAPS_API_KEY=xxx
Last step. For real. Start the app server and access it at http://0.0.0.0:5000:
$ foreman start
If you are working on pages with react support, the command to execute would be:
$ ./bin/server
Oh, and you should probably launch the gfw-api dev_apperver.py before you try to visit the site on your local machine.
Layers
Map layers, somewhat unsurprisingly, are an important part of GFW. As such, the config and code supporting them can be a bit complex. Check out the layer documentation for more information. If the component you're working on isn't in there, please write some documentation when you're done! 💞
Google Custm Search API
Global Forest Watch uses the Google Custom Search API to power it's site-wide search.
The search requests are handled inside: app/controllers/search_controller.rb
And depend on two config variables that you'll need to setup as ENV vars on
your .env
file locally or in the Heroku environment settings.
GOOGLE_SEARCH_API_KEY
GOOGLE_CUSTOM_SEARCH_CX
Currently the API being used was generated by simao.belchior@vizzuality.com
and the custom search context is owned by Alyssa Barrett on the Google Custom
Search Engine control panel.
Tests
Front-end
We have a few Javascript tests in jstest/
which you can (read: should)
run with Grunt:
grunt test
