Geocodio

Geocodio is a lightweight Ruby wrapper around the geocod.io API.

Installation

In your Gemfile:

gem 'geocodio'

Usage

The point of entry to geocod.io's API is the Geocodio::Client class. Initialize one by passing your API key or allowing the initializer to automatically use the GEOCODIO_API_KEY environment variable:

geocodio = Geocodio::Client.new('0123456789abcdef')

# Or, if you've set GEOCODIO_API_KEY in your environment:
geocodio = Geocodio::Client.new

Geocoding

The Geocodio::Client#geocode method is used to request coordinates and expanded information on one or more addresses. It is possible for a geocoding request to yield multiple results with varying degrees of accuracy, so the geocode method will always return one Geocodio::AddressSet for each query made:

results = geocodio.geocode('1 Infinite Loop, Cupertino, CA 95014')
# => #<Geocodio::AddressSet:0x007fdf23a07f80 @query="1 Infinite Loop, Cupertino, CA 95014", @addresses=[...]>

AddressSets are enumerable, so you can iterate over each result and perform operations on the addresses:

results.each { |address| puts address }

If you just want the most accurate result, use the #best convenience method:

address = results.best
# => #<Geocodio::Address:0x007fb062e7fb20 @number="1", @street="Infinite", @suffix="Loop", @city="Monta Vista", @state="CA", @zip="95014", @latitude=37.331669, @longitude=-122.03074, @accuracy=1, @formatted_address="1 Infinite Loop, Monta Vista CA, 95014">

puts address
# => 1 Infinite Loop, Cupertino CA, 95014

puts address.latitude # or address.lat
# => 37.331669

puts address.longitude # or address.lng
# => -122.03074

To perform a batch geocoding operation, simply pass multiple addresses to Geocodio::Client#geocode:

result_sets = geocodio.geocode('1 Infinite Loop, Cupertino, CA 95014', '54 West Colorado Boulevard, Pasadena, CA 91105')
# => [#<Geocodio::AddressSet:0x007fdf23a07f80 @query="1 Infinite Loop, Cupertino, CA 95014", @addresses=[...]>, #<Geocodio::AddressSet:0x007fdf23a07f80 @query="54 West Colorado Boulevard, Pasadena, CA 91105", @addresses=[...]>]

cupertino = result_sets.first.best
# => #<Geocodio::Address:0x007fb062e7fb20 @number="1", @street="Infinite", @suffix="Loop", @city="Monta Vista", @state="CA", @zip="95014", @latitude=37.331669, @longitude=-122.03074, @accuracy=1, @formatted_address="1 Infinite Loop, Monta Vista CA, 95014">

Reverse Geocoding

The interface to reverse geocoding is very similar to geocoding. Use the Geocodio::Client#reverse_geocode method (aliased to Geocodio::Client#reverse) with one or more pairs of coordinates:

addresses = geocodio.reverse_geocode('37.331669,-122.03074')
# => #<Geocodio::AddressSet:0x007fdf23a07f80 @query="1 Infinite Loop, Cupertino, CA 95014", @addresses=[...]>

address_sets = geocodio.reverse_geocode('37.331669,-122.03074', '34.145760590909,-118.15204363636')
# => [#<Geocodio::AddressSet:0x007fdf23a07f80 @query="1 Infinite Loop, Cupertino, CA 95014", @addresses=[...]>, #<Geocodio::AddressSet:0x007fdf23a07f80 @query="54 West Colorado Boulevard, Pasadena, CA 91105", @addresses=[...]>]

Coordinate pairs can also be specified as hashes:

address_sets = geocodio.reverse_geocode({ lat: 37.331669, lng: -122.03074 }, { latitude: 34.145760590909, longitude: -118.15204363636 })
# => [#<Geocodio::AddressSet:0x007fdf23a07f80 @query="1 Infinite Loop, Cupertino, CA 95014", @addresses=[...]>, #<Geocodio::AddressSet:0x007fdf23a07f80 @query="54 West Colorado Boulevard, Pasadena, CA 91105", @addresses=[...]>]

Parsing

address = geocodio.parse('1 Infinite Loop, Cupertino, CA 95014')
# => #<Geocodio::Address:0x007fa3c15f41c0 @number="1", @street="Infinite", @suffix="Loop", @city="Cupertino", @state="CA", @zip="95014", @accuracy=nil, @formatted_address="1 Infinite Loop, Cupertino CA, 95014">

Note that this endpoint performs no geocoding; it merely formats a single provided address according to geocod.io's standards.
