Hi all, I am trying to make the geometry service work but I am unsuccessful. Any idea why? Here is my code var map ; require ( [ "esri/InfoTemplate" , "esri/map" , "esri/layers/FeatureLayer" , "esri/symbols/SimpleFillSymbol" , "esri/symbols/SimpleLineSymbol" , "esri/tasks/query" , "esri/toolbars/draw" , "esri/tasks/GeometryService" , "esri/dijit/editing/Union" , "dojo/dom" , "dojo/on" , "dojo/parser" , "dojo/_base/array" , "esri/Color" , "dijit/form/Button" , "dojo/domReady!" ] , function ( InfoTemplate , Map , FeatureLayer , SimpleFillSymbol , SimpleLineSymbol , Query , Draw , GeometryService , Union , dom , on , parser , arrayUtil , Color ) { parser . parse ( ) ; var geometryService = new GeometryService ( " https://utility.arcgisonline.com/ArcGIS/rest/services/Geometry/GeometryServer " ) ; var selectionToolbar , featureLayer ; map = new Map ( "map" , { basemap : "streets" , center : [ - 97.395 , 37.537 ] , zoom : 11 } ) ; map . on ( "load" , initSelectToolbar ) ; var fieldsSelectionSymbol = new SimpleFillSymbol ( SimpleFillSymbol .

Alex, I think you may be confused about the GeomtryService (GS). The GS knows nothing about selected features or a feature layer in general. When you use GS . union ( [ this is the array of all geometries that you want combined ] ) ; So your function may look like this: require ( [ "esri/graphicsUtils" , . . . ] , function ( graphicsUtils , . . . ) { . . . . on ( featureLayer , "onSelectionComplete" , function ( features ) { if ( features . length > 1 ) { var targetGeometry = graphicsUtils . getGeometries ( featureLayer . getSelectedFeatures ( ) ) ; geometryService . union ( targetGeometry ) ; } } ) ;

Alex,

I think you may be confused about the GeomtryService (GS). The GS knows nothing about selected features or a feature layer in general. When you use

GS<SPAN class="punctuation token">.</SPAN><SPAN class="token function">union</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="punctuation token">[</SPAN><SPAN class="keyword token">this</SPAN> is the array <SPAN class="keyword token">of</SPAN> all geometries that you want combined<SPAN class="punctuation token">]</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">;</SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN></SPAN>

So your function may look like this:

<SPAN class="token function">require</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="punctuation token">[</SPAN>

The union tool looks like a charm now . For some reasons the first draw does not accomplish the union, the second draw does the job.

Now, for any of you wondering what the full code would be:

on(selectionToolbar, "DrawEnd", function (geometry) {
selectQuery.geometry = geometry;
featureLayer.selectFeatures(selectQuery,
FeatureLayer.SELECTION_NEW);
var targetGeometry = graphicsUtils.getGeometries(featureLayer.getSelectedFeatures());
geometryService.union(targetGeometry, function (geometry) {
featureLayer.clearSelection();
var symbol = new SimpleFillSymbol("none", new SimpleLineSymbol("solid", new Color([255, 255, 255]), 2), new Color([255, 255, 255, 0.25]));
var graphic = new Graphic(geometry, symbol);
map.graphics.add(graphic);
console.log(targetGeometry);
});

});

Yes I am confused by the GS and the end result of OnselectionComplete. I thought the OnselectionComplete results would be enough as geometries to pass into the GS. Thanks for the help here Robert.

Alex,

I think you may be confused about the GeomtryService (GS). The GS knows nothing about selected features or a feature layer in general. When you use

GS<SPAN class="punctuation token">.</SPAN><SPAN class="token function">union</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="punctuation token">[</SPAN><SPAN class="keyword token">this</SPAN> is the array <SPAN class="keyword token">of</SPAN> all geometries that you want combined<SPAN class="punctuation token">]</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">;</SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN></SPAN>

So your function may look like this:

<SPAN class="token function">require</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="punctuation token">[</SPAN>
&nbsp; <SPAN class="string token">"esri/graphicsUtils"</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="punctuation token">.</SPAN><SPAN class="punctuation token">.</SPAN><SPAN class="punctuation token">.</SPAN>

<SPAN class="punctuation token">.</SPAN><SPAN class="punctuation token">.</SPAN><SPAN class="punctuation token">.</SPAN><SPAN class="punctuation token">.</SPAN>

Right thank you Robert, I corrected it:

var targetGeometry = features.geometry;

featureLayer.getSelectedFeatures().setGeometry(uniongeometries);

However I am still unsuccessful.

The selection is made and shows up but not the union.

Alex,

The GeometryService.union is suppose to called on an array of geometries that you want to union. In your code you are only passing one geometry.
