Use Pointcluster with State Plane coordinates

JohnPreston — Thu, 19 Nov 2015 21:08:09 GMT

I've used the point clusterer with ArcGIS base maps where I store the x,y in that spatial reference. I would like to use the tool with x,y stores in State Plane coordinates of Washington (spatial reference 2926). I am having problems getting it to work. The cluster points show up in Algeria (not Washington). What am I missing?

function addClusters(resp) {

var obj = jQuery.parseJSON(resp.d);

var photoInfo = {};

var wgs = new SpatialReference({

"wkid": 2926

var photocnt = 0;

function (p) {

var rec = p.split(";");

var latlng = new Point(parseFloat(rec[1]), parseFloat(rec[2]), wgs);

var attributes = {

"RequestID": rec[0]

return {

"x": latlng.x,

"y": latlng.y,

"attributes": attributes

var popupTemplate = new PopupTemplate();

"");

"ID:${RequestID} " +

"Type: " +

"<a rel='external' target='_blank' href='SWUViewInspectionDetail.htm?id=${ID}'>Details</a>");

// cluster layer that uses OpenLayers style clustering

new ClusterLayer({

"data": photoInfo.data,

"distance": 50,

"id": "clusters",

"labelColor": "#fff",

"labelOffset": 10,

"resolution": map.extent.getWidth() / map.width,

"singleColor": "#888",

"singleTemplate": popupTemplate

var defaultSym = new SimpleMarkerSymbol().setSize(4);

var renderer = new ClassBreaksRenderer(defaultSym, "clusterCount");

var picBaseUrl = "http://static.arcgis.com/images/Symbols/Shapes/";

var blue = new PictureMarkerSymbol(picBaseUrl + "BluePin1LargeB.png", 32, 32).setOffset(0, 15);

var green = new PictureMarkerSymbol(picBaseUrl + "GreenPin1LargeB.png", 64, 64).setOffset(0, 15);

var red = new PictureMarkerSymbol(picBaseUrl + "RedPin1LargeB.png", 72, 72).setOffset(0, 15);

// close the info window when the map is clicked

"click", cleanUp);

// close the info window when esc is pressed

"key-down", function (e) {

if (e.keyCode === 27) {

}

The problems appears to be that spatial reference of map is 2926 but spatial reference of cluster layer is 4326. I have tried setting the spatial reference of cluster layer with no luck.
