Data model
Both methods return an array of Geogle::Model::Place. Each place is composed by:
-
Coordinates:
- lat: Float
- lng: Float
-
Area:
- northeast: Coordinates
- southwest: Coordinates
-
Geometry:
- location: Coordinates
- location_type: String
- bounds: Area
- viewport: Area
-
address:
- street_number: String
- street: String
- locality: String
- area_level_1: String
- area_level_1_code: String
- area_level_2: String
- area_level_2_code: String
- country: String
- country_code: String
- formatted: String
By address without an account
client = Geogle::Geocoder.new({ sensor: false, language: "es" })
client.address("Blasco Ibañez, Valencia")
By address making use of the components
client = Geogle::Geocoder.new({ sensor: false, language: "es" })
components = { country: 'ES' }
client.address("Blasco Ibañez, Valencia", components)
Available components to be used can be found here: https://developers.google.com/maps/documentation/geocoding/#ComponentFiltering
Reverse geocoding (by latitude and longitude)
Geogle::Geocoder.new.latlng(39.5073225, -0.2914778)
Using a business account
client = Geogle::Geocoder.new({ client_id: "gme-client-id", crypto_key: "crypto-key" })
client.latlng(39.5073225, -0.2914778)
The signature required to do the request will be appended in the URL.
Directions
Google directions documentation: https://developers.google.com/maps/documentation/directions/
Setting parameters
The same as with Geocode.
Options
- mode: supporterd modes of transport (bicycling|walking|driving).
- waypoints: specifies an array of waypoints to alter a route by routing it through the specified location.
-
alternatives: if
true
returns more than one route. -
avoid:
- tolls: the route should avoid toll roads/bridges.
- highways: the route should avoid highways,
-
units:
- metric: usage of metric system, returning distances in meters and kilometers.
- imperial: usage of imperial system (British), returning distances in miles and feet.
- region: the code of the country to search in.
Data model
Return an array of Geogle::Model::Route. Each route is composed by:
-
Time:
- value: Integer
- text: String
- time_zone: String
-
TextValue:
- value: Integer
- text: String
-
Leg:
- steps: Step
- distance: TextValue
- duration: TextValue
- arrival_time: Time
- departure_time: Time
- start_address: String
- end_address: String
- start_location: Coordinates
- end_location: Coordinates
-
Route:
- summary: String
- legs: Array[Leg]
- waypoint_order: Array[Integer]
- bounds: Area
- copyrights: String
- warnings: Array[String]
- helper methods:
- duration: Total duration of all legs.
- distance: Total distance of all legs.
- origin: Name of starting address.
- destination: Name of destination address.
- path: Array of geo-location points that represents the entire path of all legs.
Search using address names for origin and destination
options = { region: "de", mode: "driving" }
client = Geogle::Directions.new
client.routes("Berlin", "Munich", options)
Search using geo-locations for origin and destination
client = Geogle::Directions.new
client.routes("39.4699889,-0.3759178", "40.4167158,-3.7037799")
