Quick Google Geocoding Micro Gem

README.md

GGCode

GGCode is a small Google Maps API Geocoder using the Google Maps API v3.

Usage is extremely easy:

1. Add to your gemfile

   gem 'ggcode', :git => 'https://gist.github.com/bulters/5133207'

2. bundle

Reason I'm using this micro-gem is that the Graticule gem does not support the Google Maps API v3 and v2 is recently retired (8-3-2013).

ggcode.gemspec

  s.platform     = Gem::Platform::RUBY

  s.files        = ['ggcode.rb']
  s.require_path = '.'

  s.author      = 'Jeroen Bulters'

  s.add_development_dependency('httparty', ["~> 0.10.2"])
end

ggcode.rb

class GGCode
  BASE_GOOGLE_URI = "https://maps.googleapis.com/maps/api/geocode/json"
  def self.geocode(address)
    url = BASE_GOOGLE_URI + "?address=#{ CGI.escape(address) }&sensor=false"
    response = HTTParty.get(url)
    if response.code == 200 && response.parsed_response && response.parsed_response["results"].length > 0
      location = response.parsed_response["results"][0]["geometry"]["location"]
      {:latitude => location["lat"], :longitude => location["lng"] }
    else
      nil
    end
  end
end
