This one is strange: i have a map that takes features from a gp service and turns them into a graphics layer. If i add the layer, for some reason the map's spatialreference changes from 4686 to 4326, if i comment that line, the change does not happen.

The features exposed by the service come in 4686, below is the relevant part

Picture taken from the rest page

Even worse, the table where data is stored, was created via arccatalog wid wkid 4686. So, i have absolutely no idea where this 4326 is coming from.

        slider: false,
        spatialReference: { wkid: 4686 }

        gp = new esri.tasks.Geoprocessor("...");
        gp.submitJob({}, completeCallback, statusCallback);

    function completeCallback(jobInfo){

            var gl = new esri.layers.GraphicsLayer();

            for (var i = 0; i < results.value.features.length; i++) {
                if (results.value.features[i].geometry != null) {                   
            mapa.addLayer(gl); // <-- THIS IS THE PROBLEMATIC LINE

    function statusCallback(jobInfo) {

  • Can you paste a feature Json that comes back Jan 21, 2015 at 22:59
  • What if you do not add graphics and just add the layer? Is it still a problem? Jan 22, 2015 at 3:12
  • @AamirSuleman hi aamir, yes, if i add an empty layer the problem persists (commenting the whole for). As for the json, since i am working with sensible info i cannot paste it online. however i can tell you that it seems all right, it has all the fields, it has all the data it should have, the geometries for every feature are right. thanks Jan 22, 2015 at 15:02

4686 works for FeatureLayers. Don't add GraphicsLayer just by itself. You must add a base layer.

Try this example to test a map with just a FeatureLayer, using the map extent in the question


Change the value of bounds like this

var bounds = new esri.geometry.Extent(-82.00, 4.50, -66.00, 14.00, new esri.SpatialReference({ wkid:4686 }));

The FeatureLayer is projected to 4686

But, in your case you must add a base layer.

var gl = new esri.layers.GraphicsLayer();
var dynamicMapServiceLayer = new esri.layers.ArcGISDynamicMapServiceLayer("http://sampleserver6.arcgisonline.com/arcgis/rest/services/WorldTimeZones/MapServer");


And your projection will stick to 4686
