|
* Provides geocoding via a {@link https://opencagedata.com/|OpenCage} server.
|
* @alias OpenCageGeocoderService
|
* @constructor
|
*
|
* @param {Resource|String} url The endpoint to the OpenCage server.
|
* @param {String} apiKey The OpenCage API Key.
|
* @param {Object} [params] An object with the following properties (See https://opencagedata.com/api#forward-opt):
|
* @param {Number} [params.abbrv] When set to 1 we attempt to abbreviate and shorten the formatted string we return.
|
* @param {Number} [options.add_request] When set to 1 the various request parameters are added to the response for ease of debugging.
|
* @param {String} [options.bounds] Provides the geocoder with a hint to the region that the query resides in.
|
* @param {String} [options.countrycode] Restricts the results to the specified country or countries (as defined by the ISO 3166-1 Alpha 2 standard).
|
* @param {String} [options.jsonp] Wraps the returned JSON with a function name.
|
* @param {String} [options.language] An IETF format language code.
|
* @param {Number} [options.limit] The maximum number of results we should return.
|
* @param {Number} [options.min_confidence] An integer from 1-10. Only results with at least this confidence will be returned.
|
* @param {Number} [options.no_annotations] When set to 1 results will not contain annotations.
|
* @param {Number} [options.no_dedupe] When set to 1 results will not be deduplicated.
|
* @param {Number} [options.no_record] When set to 1 the query contents are not logged.
|
* @param {Number} [options.pretty] When set to 1 results are 'pretty' printed for easier reading. Useful for debugging.
|
* @param {String} [options.proximity] Provides the geocoder with a hint to bias results in favour of those closer to the specified location (For example: 41.40139,2.12870).
|
*
|
* @example
|
* // Configure a Viewer to use the OpenCage Geocoder
|
* var viewer = new Cesium.Viewer('cesiumContainer', {
|
* geocoder: new Cesium.OpenCageGeocoderService('https://api.opencagedata.com/geocode/v1/', '<API key>')
|
* });
