This example shows how to create a Leaflet map with a basemap and an empty CartoDB.js layer. Once the layer is created a function is attached the event of the layers selector checkboxes so on any state change, the sublayers are removed and recreated according to the user selection.

On this map we create two CartodB layers, one of them is built with two sublayers. In order to control when they are added to the map, we save the promises objects and use the jQuery.when function to execute the code to add the layers to the map when both promises are executed.

My goal here was the create a routable graph for Chicago.

I used Ubuntu 12.04LTS on an m2.4xlarge just to be sure memory wasn't too much of an issue.

Install

Start a screen session and start downloading an OSM extract (I used this extract of Illinois). In another screen I did the following:

  sudo apt-get update && sudo apt-get upgrade -y

sudo apt-get -y install git make cmake build-essential \

Install Cucumber with Rspec, Guard, Factory Girl(?) and Spork

Using during Hartl rails 4.0 guide (http://ruby.railstutorial.org/chapters)
