My added point is in BFE

[JohnCorrea]

Well not necessarily Bum Effing Egypt but 200 km south of Ghana. This means that my points coordinates are at 0. But why?

Here is my code.

dojo.require("dijit.dijit");
    dojo.require("dijit.layout.BorderContainer");
    dojo.require("dijit.layout.ContentPane");
    dojo.require("esri.map");
    dojo.require("esri.arcgis.utils");
    dojo.require("esri.dijit.Legend");
    dojo.require("esri.dijit.Scalebar");

    esri.config.defaults.geometryService = new esri.tasks.GeometryService('http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Geometry/GeometryServer');
     

   
    var map;
    var x = eval('@Model.Longitude'), y = eval('@Model.Latitude');


    function init() {

        var mapid = "61b91bd7159d4712ac50988e5fd7d4c7"
        var mapDeferred = esri.arcgis.utils.createMap(mapid, "map", {
            mapOptions: {
                slider: true,
                nav: false
            }

        });

        mapDeferred.addCallback(function (response) {

            map = response.map;

            //resize the map when the browser resizes
            dojo.connect(dijit.byId('map'), 'resize', map, map.resize);
            //add the legend

            if (map.loaded) {
                addPointToMap( x, y );
            }
            else {
                dojo.connect(map, "onLoad", function () {
                    addPointToMap(x, y);
                });
            }
        });
        mapDeferred.addErrback(function (error) {
            console.log("Map creation failed: ", dojo.toJson(error));
        });

    }


    function addPointToMap(lon, lat) {
    

        var point = new esri.geometry.Point(parseFloat(lon), parseFloat(lat), new esri.SpatialReference({ wkid: 4326 }));

       
       
        var symbol = new esri.symbol.SimpleMarkerSymbol().setColor(new dojo.Color([0, 255, 0]));
        var graphic = new esri.Graphic(point, symbol);


        map.graphics.add(graphic);

    }

    dojo.ready(init);
   

</script>
<div id="map"  style="width: 650px; height: 600px; border: 1px solid #000;">
</div>

Assuming that your map is in Web Mercator projection, you probably need to re-project your points from decimal degrees.

See the geographicToWebMercator help doco.

Yep, that did it.

It was as simple as wrapping the new point definition in this function:

var point = esri.geometry.geographicToWebMercator(
            new esri.geometry.Point(lon, lat, new esri.SpatialReference({ wkid: 4326 }))
        );

Thank you sir!
