Maps SDK for Web

tt.services.geocode

Allows requests to be made using the TomTom's Search API - Geocode.

Parameters need to be passed to the constructor. The method go performs the actual call.

The SDK provides a Promise polyfill for browsers (IE<9) without native ECMAScript 6 support.

Constructor

tt.services.geocode([options])

Example
function callbackFn(result) {
  console.log(result);
};
tt.services.geocode({
  key: <Your API Key>,
  query: 'Amsterdam, The Netherlands'
})
.go()
.then(callbackFn);
Parameters
Name Description
options
Object
default:None 		Options to be passed to the geocode call, or an array of such option objects to perform a batch request.
options.bestResult
Boolean
default:false 		Defines whether the geocode service should return the best result.
It makes the service instances to return only one result, the best match result. This option overwrites both limit and offset parameters. It changes the response from an array to a single result.
options.boundingBox
Object | Number[] | Object[] | String
default:None 		Bounding box area in one of the supported formats.
The bounding box is a limited area within the search results. If it is omitted then the whole world will be taken into consideration. In case the area specified exceeds the world boundaries, the following actions will be taken depending on which side was exceeded:
  • Latitudes: the exceeded values will be replaced with their maximun.
  • Longitudes: The service will split the area into two (or more) valid bounding boxes, will execute a search request for each one, and then merge the responses into a single result.
This option is able to convert a number of popular formats into the bounding box. The supported formats are listed below:
  • Maps.LngLatBounds class instance
  • {minLon: 0, minLat: 0, maxLon: 1, maxLat: 1} A plain object with the keys minLon, minLat, maxLon, maxLat.
  • [0, 0, 1, 1] An array of numbers describing the bounding box following the order: minLon, minLat, maxLon, maxLat.
  • [[0, 0], [1, 1]] A two-dimensional array with two indexes [southWest, northEast], each one with longitude and latitude values.
  • "0,0,1,1" A comma-separated string with numbers in the order: minLon, minLat, maxLon, maxLat.
  • [{lon: 0, lat: 0},{lon: 1, lat: 1}] A one-dimensional array with two objects in the order: southWest, northEast, and each object with a lat and lon key.
  • [{lng: 0, lat: 0},{lng: 1, lat: 1}] A one-dimensional array with two objects in the order: southWest, northEast and each object with a lat and lon key.
  • [Maps.LngLat, Maps.LngLat] A one-dimensional array with two Maps.LngLat instances in the order: southWest and northEast.
options.center
Object | Number[] | String[] | String
default:None 		Longitude and latitude data in one of the supported formats.
This option represents a geographic coordinate. The supported formats are listed below:
  • Maps.LngLat The Class instance.
  • [0, 0] A one-dimensional array with two indexes for longitude and latitude respectively.
  • ["0", "0"] A one-dimensional array with two indexes for longitude and latitude respectively.
  • "0,1" A string with longitude and latitude divided by a comma.
  • {lng: Function, lat: Function} An object with two functions returning longitude and latitude.
  • {lon: 0, lat: 1} An object with two keys: lat and lon.
  • {lng: 0, lat: 1} An object with two keys: lat and lng.
  • {x: 0, y: 1} An object with two keys: x as longitude and y as latitude.
  • {longitude: 0, latitude: 1} An object with two keys: longitude and latitude.
Note: Supplying the center without a radius will bias search results only to that area.
options.countrySet
String
default:None 		Comma separated list of country codes (e.g.: FR,ES)
This option is a list of country codes used to limit the search request to those specific political limits.
options.extendedPostalCodesFor
String
default:None 		Represent the indexes for extended postal codes.
Represent the indexes for which extended postal codes should be included in the results. The available indexes codes are:
  • Addr: Address ranges
  • Geo: Geographies
  • PAD: Point Addresses
  • POI: Points of Interest
  • Str: Streets
  • XStr: Cross Streets (intersections)
The value should be a comma-separated list of index types (in any order) or just the string "None" for no indexes.
Example
tt.services.geometrySearch({
  query: 'pizza',
  extendedPostalCodesFor: 'PAD,Addr,POI'
})
.go()
.then(handleResults);

The extended postal code will be returned as an extendedPostalCode property of an address.
options.key
String
default:None 		A valid API Key for the requested service.
A valid API Key is required to make use of the given service. It can be issued in the Developer Portal.
options.language
String
default:null 		Language code that decides in which language the results should be returned.
The value should correspond to one of the supported IETF language codes. The list is available here. The code is case insensitive.
options.limit
Number
default:10 		The maximum number of responses that will be returned.
Represents the maximum number of responses that will be returned per request. The maximum value is 100.
options.offset
Number
default:None 		A positive integer value.
Use this option if you want to apply an offset to the results returned by the Search API service. It makes use of the ofs parameter which allows paginated results when used with the limit option. The maximum value is 1900.
options.protocol
"http" | "https"
default:"https" 		The protocol type to be used in the calls.
Represents the type of protocol used to perform a service call.
options.query
String
default:None 		The query string. This value will be properly encoded during the creation of the request.
This option represents the text that will be searched.
options.radius
Number
default:None 		A positive integer value in meters.
This option specifies the search radius in meters using the coordinates given to the center option as origin.
options.typeahead
Boolean
default:false 		Enables or disables the option.
If this option is enabled, the query will be interpreted as a partial input and the search will enter predictive mode.
