How to Calculate Distance Between Two Give Points

Question

Using ArcGIS API for JavaScript 3.22 and having two given Points as var pt1 = new Point(-106.61, 35.1107, new SpatialReference({ wkid: 4326 })); var pt2 = new Point(-108.61, 35.1107, new SpatialReference({ wkid: 4326 }));‍‍ can you please let me know how I can calculate the distance from `pt1 to `pt2`? var map; require([ "esri/map", "esri/geometry/Point", "esri/SpatialReference", "esri/geometry/webMercatorUtils", "dojo/domReady!" ], function(Map, Point, SpatialReference, webMercatorUtils) { map = new Map("map", { basemap: "topo", center: [-106.61, 35.1107], zoom: 8 }); geometryService = new esri.tasks.GeometryService("https://utility.arcgisonline.com/ArcGIS/rest/services/Geometry/GeometryServer"); var pt1 = new Point(-106.61, 35.1107, new SpatialReference({ wkid: 4326 })); var pt2 = new Point(-108.61, 35.1107, new SpatialReference({ wkid: 4326 })); });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Bengi, Here is your code updated for that: var map; require([ "esri/map", "esri/geometry/Point", "esri/SpatialReference", "esri/tasks/GeometryService", "esri/tasks/DistanceParameters", "dojo/domReady!" ], function(Map, Point, SpatialReference, GeometryService, DistanceParameters ){ map = new Map("map", { basemap: "topo", center: [-106.61, 35.1107], zoom: 8 }); geometryService = new GeometryService("https://utility.arcgisonline.com/ArcGIS/rest/services/Geometry/GeometryServer"); var pt1 = new Point(-106.61, 35.1107, new SpatialReference({ wkid: 4326 })); var pt2 = new Point(-108.61, 35.1107, new SpatialReference({ wkid: 4326 })); var distParams = new DistanceParameters(); distParams.distanceUnit = GeometryService.UNIT_STATUTE_MILE; distParams.geometry1 = pt1; distParams.geometry2 = pt2; distParams.geodesic = true; geometryService.distance(distParams, function(distance) { //result = distance; }); });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
