Hey everybody, tagging on to this discussion, I had another question. Robert Scheitlin, GISP​ was able to help me out per usual, but I ran into another problem. I want to use a Multipoint Geometry to select all features in a polygon that intersect with a point from the multipoint geometry. Here is the code I have so far: var myButton2 = new Button({   label: "Analyze",   onClick: function(){   //var selectedCity = [];   //var allPoints = [];   var mp = new Multipoint();    arrayUtils.map(NewLayer.graphics, function(gra){    mp.addPoint(gra.geometry);    //allPoints.push(gra);   });    console.log(mp);   var query = new Query();   //for (var i = 0; i < allPoints.length; i++) {   //query.geometry = allPoints.geometry;   //thisIsaTest = ft6select.selectFeatures(query,FeatureLayer.SELECTION_ADD, function(evt2){   //if(evt2.length > 0){   //var tutu = evt2[0].geometry;   //selectedCity.push(tutu);   //console.log(selectedCity);   //}   //});   //}   console.log(selectedCity);   query.geometry = mp;   ft6select.selectFeatures(query);   } }, "progButtonNode2").startup(); ft6select.on('selection-complete', function (evt){   console.log(evt); }); This code returns an empty array, meaning nothing has been selected. When I use the commented out method, using each point of the multipoint geometry, it does select features that intersect with each point. I hope this makes any sense. Tim ... View more

Hey everybody, I am looking for a way to select points from a feature layer that fall within this feature layer: Layer: Atl_slr_merged_2ft (ID: 6) It sounds easy enough if you use ArcGIS Desktop but in javascript I am running into issues. Using the method described here would work, union and then use the geometry of the union feature to select what falls within it. But if your feature layer has thousands of polygons, the union would take forever. So my question is, am I approaching this issue wrong? Is my only option to union the layer before publishing it on a server ( which I sadly can't do, because I don't have the feature layer and rely on NOAA hosting it). Any input would be greatly appreciated! Thanks, Tim ... View more
