I have a polygon feature with different names for each polygon I have a habitat raster layer with a bunch of classifications (this is clipped to all the polygons above) I want to run statistics on the Habitat layer where it falls inside the polygon layer, its already clipped so we're good there. Result:  I am looking for the polygon feature name with the statistics of each habitat type and their sum in that polygon     Polygon            Trees        Water         developed Polygon x            50             21                 55 Polygon z            152           66                 88 ANY IDEAS on how to do this? ...

I have a query that: is selecting features via a Buffers Geometry It grabs that array, pushed to a Function and does a Unique filter on that array It then returns it to a table created via JavaScript. I am not seeing a fully unique return set....as you can see in the attachment there are two "sunfish, bluespotted" being returned even thought he COMMON_NAME field is the same as specified in the Unique Filter. I am wondering if this is not working correctly? do I have something set up wrong? It is decreasing the number of returned records but does not seem to be getting all of unique values....I checked my data and this field seems to be unique, wondering if I am doing something wrong. // SNIP..... var query3 = new Query();    query3.geometry = bufferGeometry;   // Select the Points within the Buffer and show them    featureLayerVAFWIS.selectFeatures(query3, FeatureLayer.SELECTION_NEW, function(results){    });    // Query for the records with the given object IDs and populate the grid    featureLayerVAFWIS.queryFeatures(query3, function (featureSet) {   updateGrid3(featureSet); }); function updateGrid3(featureSet) {   var data = arrayUtils.map(featureSet.features, function (entry, i) {    return {   id: entry.attributes.OBJECTID,   ObsID: entry.attributes.ObsID,   SppBova: entry.attributes.SppBova,   COMMON_NAME: entry.attributes.COMMON_NAME,   GENUS: entry.attributes.GENUS,   SPECIES: entry.attributes.SPECIES,   Tier: entry.attributes.Tier,   FedStatus: entry.attributes.FedStatus,   TaxaGrp: entry.attributes.TaxaGrp,    };   });   var uniqueName = [];   var UniquValues = array.filter(data, function (item) {         var IsNameUnique = true;        array.forEach(uniqueName, function (value) {       if (value == (item.COMMON_NAME)) {           IsNameUnique = false;        }        });        if (IsNameUnique) {          uniqueName.push(item.COMMON_NAME);        }        return IsNameUnique;    });     var i;     var out = "<table id=t01>";     for(i = 0; i < uniqueName.length; i++) {         out += "<tr><td>" +         arr.id +         "</td><td>" +         arr.ObsID +         "</td><td>" +         arr.SppBova +         "</td><td>" +         arr.COMMON_NAME +         "</td><td>" +         arr.GENUS +         "</td><td>" +         arr.SPECIES +         "</td><td>" +         arr.Tier +         "</td><td>" +         arr.FedStatus +         "</td><td>" +         arr.TaxaGrp +         "</td></tr>";     }     out += "</table>";     document.getElementById("id01").innerHTML = out;   dom.byId('upload-function').innerHTML = "See Results below";   domStyle.set(loadingShapefile, "display", "none"); } ...
