Ruby implementation of Google RouteBoxer

http://google-maps-utility-library-v3.googlecode.com/svn/trunk/routeboxer/src/RouteBoxer.js

Add this line to your application's Gemfile:

gem 'route_boxer'

And then execute:

$ bundle

Or install it yourself as:

$ gem install route_boxer

1. Get route with Google Directions API:

    results = JSON.parse(open("http://maps.googleapis.com/maps/api/directions/json?alternative=true&destination=Warsaw&language=en&mode=driving&origin=Cracow&sensor=false").read)

2. Decode response to LatLng points with 'polylines' gem:

    points = Polylines::Decoder.decode_polyline(result["routes"][0]["overview_polyline"]["points"])

3. Parse points to RouteBoxer::LatLng objects:

   points = points.map { |p| RouteBoxer::LatLng.new(p[0], p[1])}

4. Use RouteBoxer to get 'boxed' route:

   RouteBoxer::Core.new.box(points, 10)
