Geocoder

AMap.Geocoder

Geocoding and reverse geocoding class, used for conversion between address descriptions and latitude/longitude coordinates. Users can obtain query results through callback functions. Construct a geocoding and reverse geocoding object, and set its properties through GeocoderOptions.

new AMap.Geocoder(opts: GeocoderOptions)

Tutorial

Parameter

options (GeocoderOptions): Geocoding and reverse geocoding parameters

Attribute	Type	Description
city	string	City. During geocoding, set the city where the address description is located. Optional values: citycode, adcode. City code table
radius	number	During reverse geocoding, the range centered on the given coordinates, in meters. Value range: 0 - 3000. Default: 1000
lang	string	Set language type. Optional values: zh_cn (Chinese), en (English). Default: zh_cn (Chinese)
batch	boolean	Whether to batch query; when batch is set to false, only the first record is returned
extensions	string	When reverse geocoding, the level of detail in the returned information defaults to 'base', returning basic address information; set to 'all', it returns address information along with nearby POIs, roads, road intersections, etc.

Demo

AMap.plugin("AMap.Geocoder", function () {
  var geocoder = new AMap.Geocoder({
    radius: 1000, 
    extensions: "all", 
  });
  var lnglat = [-73.98751,40.74129];
  geocoder.getAddress(lnglat, function (status, result) {
    if (status === "complete" && result.info === "OK") {
      // result is the corresponding detailed geographic information
    }
  });
});

Method

getLocation(keyword, cbk)

Convert address information into Gaode latitude and longitude coordinates

Parameter:

keyword (String) Keyword

cbk (GeocoderCallback) Callback function

Demo:

var address = "9, Madison Avenue, 曼哈顿, 纽约, 纽约州, 美国";
geocoder.getLocation(address, function (status, result) {
  if (status === "complete" && result.info === "OK") {
    // result is the corresponding detailed geographic information
  }
});

setCity(city)

When geocoding, set the city for the address description

Parameter: city (String) City

Demo:

geocoder.setCity("010");

getAddress(location, cbk)

Convert latitude and longitude coordinates into structured address information

Parameter:

location(LngLat | Array<LngLat>) Given coordinates

cbk (ReGeocoderCallback) Callback function

Demo:

var lnglat = [116.396574, 39.992706];
geocoder.getAddress(lnglat, function (status, result) {
  if (status === "complete" && result.info === "OK") {
    // result is the corresponding detailed geographic information
  }
});
