Guide to Geocoding APIs

This is a list of geocoding APIs supported by the Geocoder gem. Before using any API in a production environment, please read its official Terms of Service (links below).

Table of Contents

Street Address Lookups

Google (:google)

Google Maps API for Work (:google_premier)

Similar to :google, with the following differences:

  • API key: required, plus client and channel (set Geocoder.configure(lookup: :google_premier, api_key: [key, client, channel]))
  • Key signup: https://developers.google.com/maps/premium/
  • Quota: 100,000 requests/24 hrs, 10 requests/second

Google Places Details (:google_places_details)

The Google Places Details API is not, strictly speaking, a geocoding service. It accepts a Google place_id and returns address information, ratings and reviews. A place_id can be obtained from the Google Places Search lookup (:google_places_search) and should be passed to Geocoder as the first search argument: Geocoder.search("ChIJhRwB-yFawokR5Phil-QQ3zM", lookup: :google_places_details).

Google Places Search (:google_places_search)

The Google Places Search API is the geocoding service of Google Places API. It returns very limited location data, but it also returns a place_id which can be used with Google Place Details to get more detailed information. For a comparison between this and the regular Google Geocoding API, see https://maps-apis.googleblog.com/2016/11/address-geocoding-in-google-maps-apis.html

  • Same specifications as Google Places Details (see above).

Local IP Address Lookups

MaxMind Local (:maxmind_local) - EXPERIMENTAL

This lookup provides methods for geocoding IP addresses without making a call to a remote API (improves speed and availability). It works, but support is new and should not be considered production-ready. Please report any bugs you encounter.

  • API key: none (requires the GeoLite City database which can be downloaded from MaxMind)
  • Quota: none
  • Region: world
  • SSL support: N/A
  • Languages: English
  • Documentation: http://www.maxmind.com/en/city
  • Terms of Service: ?
  • Limitations: ?
  • Notes: There are two supported formats for MaxMind local data: binary file, and CSV file imported into an SQL database. You must download a database from MaxMind and set either the :file or :package configuration option for local lookups to work.

To use a binary file you must add the geoip (or jgeoip for JRuby) gem to your Gemfile or have it installed in your system, and specify the path of the MaxMind database in your configuration. For example:

Geocoder.configure(ip_lookup: :maxmind_local, maxmind_local: {file: File.join('folder', 'GeoLiteCity.dat')})

To use a CSV file you must import it into an SQL database. The GeoLite City and Country packages are supported. Configure like so:

Geocoder.configure(ip_lookup: :maxmind_local, maxmind_local: {package: :city})

You can generate ActiveRecord migrations and download and import data via provided rake tasks:

# generate migration to create tables
rails generate geocoder:maxmind:geolite_city

# download, unpack, and import data
rake geocoder:maxmind:geolite:load PACKAGE=city

You can replace city with country in any of the above tasks, generators, and configurations.

GeoLite2 (:geoip2)

This lookup provides methods for geocoding IP addresses without making a call to a remote API (improves speed and availability). It works, but support is new and should not be considered production-ready. Please report any bugs you encounter.

  • API key: none (requires a GeoIP2 or free GeoLite2 City or Country binary database which can be downloaded from MaxMind)

  • Quota: none

  • Region: world

  • SSL support: N/A

  • Languages: English

  • Documentation: http://www.maxmind.com/en/city

  • Terms of Service: ?

  • Limitations: ?

  • Notes: You must download a binary database file from MaxMind and set the :file configuration option. The CSV format databases are not yet supported since they are still in alpha stage. Set the path to the database file in your configuration:

    Geocoder.configure( ip_lookup: :geoip2, geoip2: { file: File.join('folder', 'GeoLite2-City.mmdb') } )

You must add either the hive_geoip2 gem (native extension that relies on libmaxminddb) or the maxminddb gem (pure Ruby implementation) to your Gemfile or have it installed in your system. The pure Ruby gem (maxminddb) will be used by default. To use hive_geoip2:

Geocoder.configure(
  ip_lookup: :geoip2,
  geoip2: {
    lib: 'hive_geoip2',
    file: File.join('folder', 'GeoLite2-City.mmdb')
  }
)
