Measurement is meter square

xxxlll — Tue, 12 Dec 2017 20:23:07 GMT

Hello everyone.

In this sample code can I measure the area of the selected area as Meter square. It is given in acres .

var area = geometryEngine.geodesicArea(polygon, "acres");
if (area < 0) {
   var simplifiedPolygon = geometryEngine.simplify(polygon);
   if (simplifiedPolygon) {
      area = geometryEngine.geodesicArea(simplifiedPolygon, "acres");
   }
}

anything geodesic I am sure you can specify the coordinates. Perhaps it is in acres because the projection uses feet for coordinates. What does the documentation for that method show?

Check this doc: geometryEngine | API Reference | ArcGIS API for JavaScript 4.5

Use square-meters as paramater
