Bulk Reverse Geocoding Not Working

BehrouzHosseini — Sun, 12 Dec 2021 05:09:33 GMT

Using ArcGIS JavaScript API 3.19 I am trying to do a bulk reverse geocoding like

var locator = new Locator("http://dummydomain:6080/arcgis/rest/services/TestGeocoder/GeocodeServer");
 map.on("load", function(evt) {
   var points= [{
                 "x": -83.000369,
                 "y": 40.055185
                 }, {
                 "x": -83.000031,
                 "y": 40.051250
                 }];
    locator.outSpatialReference = map.spatialReference;
    var options = {addresses: points};
    locator.locationToAddress(options);
 });‍‍‍‍‍‍‍‍‍‍‍‍‍

I am not getting any error on page but the map screen looks empty! can you please let me know what I am doing wrong? and how I can export the points address to console? Thanks

Bengi,

There is no bulk reverse geocoding ability. The method is locationToAddress (singular not plural). The best you can do is use a promise all.

Thanks for reply Robert,

The promise all looks very complicated! In order to get a better understanding, can you please let me know why this code also not working?!

$('#locator').on("click", function() {
    locator.outSpatialReference = map.spatialReference;
    locator.locationToAddress(webMercatorUtils.webMercatorToGeographic(-83.000369,40.055185), 100);
 });‍‍‍‍

As you can see I am only passing X and Y of one single location to locationToAdress()! and in return I am getting this error

dojo.io.script error Error: Unable to complete operation.

Bengi,

In your code you are using:

webMercatorUtils.webMercatorToGeographic(-83.000369,40.055185)‍

webMercatorUtils.webMercatorToGeographic is expecting a geometry, not a string and for that matter you are providing a lat lon so it is already geographic. So there is no need to use webMercatorUtils.webMercatorToGeographic. You need to use something like:

locator.locationToAddress(new Point(-83.000369,40.055185, new SpatialReference({ wkid: 4326 })), 100);‍‍

Thanks Again Robert,

Just one final question

As you said the locator is functioning now but when I try to get the address like this

locator.locationToAddress(new Point(-83.000369,40.055185, new SpatialReference({ wkid: 4326 })), 100);
console.info(locator.address.Street);
console.info(locator.Street);‍‍‍

I am just getting undefined in return! isn't it the address available through the locator object?

Bengi,

The locator returns a deferred object to the callback function or the location-to-address-complete event function that you have set for the Locator object. So no you can not get the result the way you are trying.

locator.locationToAddress(new Point(-83.000369,40.055185, new SpatialReference({ wkid: 4326 })), 100, function(event){
  console.info(event.address);
});‍‍‍
