Applying Heatmap Renderer to ArcGisDynamicMapServiceLayer

DanielGalati — Fri, 24 Apr 2015 13:14:02 GMT

Hello there,

I am attempting to apply a HeatMap renderer to a dynamic layer I have created. The DynamicLayer contains a point query gathered from my ArcGIS Server SDE database.

I have successfully implemented basic things such as SimpleRenderer to display the data on my map. However, whenever I attempt to use the same logic, but swap out the SimpleRenderer with HeatMapRenderer, I get errors. I am sure I am setting all parameters correctly as described in the Documentation Samples.

I am getting the following error reply from my ArcGIS Server: ":"Invalid renderer specified for dynamic dataLayer with 'id': 0."

My code is below: any help would be appreciated.

var dndSource, layerLookup, dynamicLayerInfos;

(function() {

var layerName, dataSource, layerSource, options, drawingOptions;

debugger;

///Testing Renderer

var heatmapRenderer = new HeatmapRenderer({

blurRadius: 10,

colorStops: [

{ ratio: 0, color: "rgba(250, 0, 0, 0)" },

{ ratio: 0.6, color: "rgb(250, 0, 0)" },

{ ratio: 0.85, color: "rgb(250, 150, 0)" },

{ ratio: 0.95, color: "rgb(255, 255, 0)" }],

});

var m_renderer = heatmapRenderer;

var m_queryDataSource = new QueryDataSource();

m_queryDataSource.workspaceId = biodWeb.const.gis.workSpaceID;

m_queryDataSource.geometryType = "point";

m_queryDataSource.oidFields = ["OBJECTID"];

m_queryDataSource.query = "Select OBJECTID, Shape from bioDWEB.BD.NATEARTH_10M_POPULATED_PLACES";

m_queryDataSource.spatialReference = new SpatialReference({ wkid: 102100 });

m_queryDataSource.workspaceId = biodWeb.const.gis.workSpaceID;

var layerSource = new LayerDataSource();

layerSource.dataSource = m_queryDataSource;

//---------- Dynamic layer

layerName = "add a new layer from database";

var usaLayer = new ArcGISDynamicMapServiceLayer("http://MYSERVER.COM/arcgis/rest/services/BiodWebDyn/BioD_DynamicMap/MapServer",

{ "id": "NEW LAYER" });

usaLayer.setVisibleLayers([0]);

if (!dynamicLayerInfos) {

dynamicLayerInfos = usaLayer.createDynamicLayerInfosFromLayerInfos();

}

var dynamicLayerInfo = new DynamicLayerInfo();

dynamicLayerInfo.id = 0;

dynamicLayerInfo.name = layerName;

dynamicLayerInfo.source = layerSource;

dynamicLayerInfos.push(dynamicLayerInfo);

usaLayer.setDynamicLayerInfos(dynamicLayerInfos, true);

drawingOptions = new LayerDrawingOptions();

drawingOptions.renderer = m_renderer;

options = [];

options[0] = drawingOptions;

usaLayer.setLayerDrawingOptions(options);

map.addLayer(usaLayer);

})();

Hi,

Did you get a solution to your problem? Were you able to apply a HeatMapRenderer to a ArcGisDynamicMapServiceLayer instead of a FeatureLayer?

Thanks.
