                Installing and running Project OSRM, the OpenStreetMap-based routing engine, on an Amazon EC2 instance.
              
          
    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 \

  
## index.js
var tileReduce = require('tile-reduce');
var path = require('path');

tileReduce({
  zoom: 14,
  map: path.join(__dirname, '/process.js'),
  sources: [
    {name: 'ways', mbtiles: 'ways.mbtiles')}
  ]
});

'http://www.datasciencetoolkit.org/maps/api/geocode/json?sensor=false&address=' + escape(value, 'url')'

Step Two

Parse Json for longitude:
