Geocodio Build Status Coverage Status Code Climate

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 accepts an array of addresses and an options hash. If more than one address is provided, #geocode will use Geocodio's batch endpoint behind the scenes. 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 as mentioned earlier, simply add more addresses to the passed array:

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.

Additional fields

Geocodio has added support for retrieving additional fields when geocoding or reverse geocoding. To request these fields, pass an options hash to either #geocode or #reverse_geocode. Possible fields include cd or cd113, stateleg, school, and timezone:

address = geocodio.geocode(['54 West Colorado Boulevard Pasadena CA 91105'], fields: %w[cd stateleg school timezone]).best

address.congressional_districts
# => #<Geocodio::CongressionalDistrict:0x007fa3c15f41c0 @name="Congressional District 27" @district_number=27 @congress_number=113 @congress_years=2013..2015>

address.house_district
# => #<Geocodio::StateLegislativeDistrict:0x007fa3c15f41c0 @name="Assembly District 41" @district_number=41>

address.senate_district
# => #<Geocodio::StateLegislativeDistrict:0x007fa3c15f41c0 @name="State Senate District 25" @district_number=25>

address.unified_school_district # or .elementary_school_district and .secondary_school_district if not unified
# => #<Geocodio::SchoolDistrict:0x007fa3c15f41c0 @name="Pasadena Unified School District" @lea_code="29940" @grade_low="KG" @grade_high="12">

address.timezone
# => #<Geocodio::Timezone:0x007fa3c15f41c0 @name="PST" @utc_offset=-8 @observes_dst=true>
address.timezone.observes_dst?
# => true
