GoogleMapsGeocoder

A simple Plain Old Ruby Object wrapper for geocoding with Google Maps, GoogleMapsGeocoder gives you all its geocoding functionality with these advantages:

• easy to use in only one step
• fully documented with complete test coverage
• lightweight at only 10.5 K as a gem (that's just over a tenth the size of Geocoder)
• only a single dependency, the commonly used Rack

1. Set your Google Maps API key, which Google now requires, as an environment variable:

   export GOOGLE_MAPS_API_KEY=[your key]

2. Add GoogleMapsGeocoder to your Gemfile and run bundle:

   gem 'google_maps_geocoder'

   Or try it out in irb with:

   require 'google_maps_geocoder'

GoogleMapsGeocoder is cryptographically signed. To insure the gem you install hasn’t been tampered with, add my public key as a trusted certificate and then install:

gem cert --add <(curl -Ls https://raw.github.com/FoveaCentral/google_maps_geocoder/master/certs/ivanoblomov.pem)
gem install google_maps_geocoder -P HighSecurity

chez_barack = GoogleMapsGeocoder.new 'White House'

Get the complete, formatted address:

chez_barack.formatted_address
 => "1600 Pennsylvania Avenue Northwest, President's Park, Washington, DC 20500, USA"

...standardized name of the city:

chez_barack.city
 => "Washington"

...full name of the state or region:

chez_barack.state_long_name
 => "District of Columbia"

...standard abbreviation for the state/region:

chez_barack.state_short_name
 => "DC"

The complete, hopefully self-explanatory, API is:

• GoogleMapsGeocoder#city
• GoogleMapsGeocoder#country_long_name
• GoogleMapsGeocoder#country_short_name
• GoogleMapsGeocoder#county
• GoogleMapsGeocoder#exact_match?
• GoogleMapsGeocoder#formatted_address
• GoogleMapsGeocoder#formatted_street_address
• GoogleMapsGeocoder#lat
• GoogleMapsGeocoder#lng
• GoogleMapsGeocoder#partial_match?
• GoogleMapsGeocoder#postal_code
• GoogleMapsGeocoder#state_long_name
• GoogleMapsGeocoder#state_short_name

For compatibility with Geocoder, the following aliases are also available:

• GoogleMapsGeocoder#address
• GoogleMapsGeocoder#coordinates
• GoogleMapsGeocoder#country
• GoogleMapsGeocoder#country_code
• GoogleMapsGeocoder#latitude
• GoogleMapsGeocoder#longitude
• GoogleMapsGeocoder#state
• GoogleMapsGeocoder#state_code
