Yes Neil, it could/should sit outside.  I put it inside just for demo purposes.  The main thing is to show the iteration over the polygon part vertices. ... View more

I would use a boolean variable to "manage" the visibility of the layer and just toggle the boolean value each time the button is clicked.  Then based on the boolean value set the visibility of the layer within the onclick function. var layerIsOn = false; var eventHandle = dojo.connect(node, "onclick", function addMapLayer1(e) {    layerIsOn = !layerIsOn;    if (layerIsOn) {       // switch layer on    } else {       // switch layer off    } });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ...

With Python you can iterate the polygon part vertices and write them to a new table.  You can change the field names and outputs as required.  Select a single polygon segment to only write one table and run the script from the ArcMap Python console. import arcpy mxd = arcpy.mapping.MapDocument('CURRENT') df = mxd.activeDataFrame layers = arcpy.mapping.ListLayers(df) layer = layers[0] with arcpy.da.SearchCursor(layer, ["SHAPE@", "OBJECTID"]) as lcursor: for lrow in lcursor:    polygon = lrow[0]    objId = lrow[1]    # create table for selected feature    arcpy.CreateTable_management(arcpy.env.scratchWorkspace, "pntTable_" + str(objId))    table = arcpy.env.scratchWorkspace + "\\pntTable_" + str(objId)    # add fields or use a template    arcpy.AddField_management(table, "X", "DOUBLE")    arcpy.AddField_management(table, "Y", "DOUBLE")    icursor = arcpy.da.InsertCursor(table, ["X", "Y"])    # iterate through polygon parts    part = polygon.getPart(0) # assuming a single part polygon    # list polygon part points    for pnt in part:      print "X: " + str(pnt.X) + " Y: " + str(pnt.Y)      # add to table      icursor.insertRow([pnt.X, pnt.Y])    del icursor del lcursor‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ...

The Directional Distribution tool (Directional Distribution (Standard Deviational Ellipse)—Help | ArcGIS for Desktop ) might help eliminate the outliers.  It also provides the centroid coordinates of the ellipse indicating the distribution. ... View more

You can pass any geometry in the FeatureLayer query (FeatureLayer | API Reference | ArcGIS API for JavaScript 3.17 ). var query = new Query(); query.outFields = [ "*" ]; query.geometry = myCostumExtentPolygonGeometry; featureLayer.queryFeatures(query, function(featureSet) { // process results });‍‍‍‍‍‍ ...

If you convert the KMZ back to KML (in Google Earth), you can open the KML with a text editor (e.g. Notepad) and will see that the polygon geometry is written in exactly the format you require.  Then you can just copy and paste the geometry to a new XSLT file. ... View more

You can try this script.  I'm not familiar with the ET-Geotools version, but I think it does more or less the same.  It adds the split parts to the existing polygon layer, but you can change it to write to a new feature class. import arcpy mxd = arcpy.mapping.MapDocument('CURRENT') df = mxd.activeDataFrame layers = arcpy.mapping.ListLayers(df) # select layer - my known polygon layer with only one polygon poly = layers[2] # split steps splits = [20, 30, 50] # get polygon and extent properties with arcpy.da.SearchCursor(poly, ["SHAPE@"]) as pcursor:    for prow in pcursor:       polygon = prow[0]    # polygon to cut       e = polygon.extent   # bounding extent of polygon       print e.XMin,e.YMin,e.XMax,e.YMax del pcursor # geometric cut test iteration step size - modify value to get better accuracy stepsize = 0.001 # set parameters to move from left to right over the polygon leftXstart = e.XMin leftX = e.XMin + stepsize ymax = e.YMax ymin = e.YMin cutpoly = polygon icursor = arcpy.da.InsertCursor(poly, ["SHAPE@"]) # iterate cut percentage list for i in splits[:2]:    print i    tol = 0    while tol < i:       # construct NS line       pntarray = arcpy.Array()       pntarray.add(arcpy.Point(leftX, ymax))       pntarray.add(arcpy.Point(leftX, ymin))       pline = arcpy.Polyline(pntarray,arcpy.SpatialReference(4326))          # cut polygon and get split-parts       cutlist = cutpoly.cut(pline)       tol = 100 * cutlist[1].area / polygon.area            leftX += stepsize       #print str(leftX) + ":" + str(tol)    cutpoly = cutlist[0]    # part 0 is on the right side and part 1 is on the left side of the cut    icursor.insertRow([cutlist[1]]) # insert last cut remainder icursor.insertRow([cutlist[0]]) del icursor This is the result for cutting the polygon into 20%, 30% and 50% ...

Are you referring to doing a identify/query on a layer at a specific location? Query (Operation) ​ You can run the  query operation directly from the REST endpoint for the specific layer at the bottom of the page. Then just specify the input/output values ... View more

You could add all the result features in a bigger array and then add them all at once: var queryTask = new QueryTask({     url: "http://*******/arcgis/rest/services/Test/MapServer/1" }); var time = 0; function querydata() {     var allFeatures = []; // array for all resulting features     for (var i = 0; i < 8; i++) {         var query = new Query();         query.returnGeometry = true;         //query.outFields = ["OBJECTID", "RELHEI", "name"];         query.outFields = ["*"];         var start = 0 + i * 1000         var end = start + 1000         query.where = "OBJECTID > " + start + " AND OBJECTID < " + end;         queryTask.execute(query)             .then(function(results) {                 time++;                 var l = results.features;                 //collection.addMany(results.features);                 allFeatures.push(results.features);                 if (i == 8) {                     // add when final result set has been retrieved                     collection.addMany(allFeatures);                     querylayer.source = collection;                     myMap.add(querylayer);                 }             })             .otherwise(function(error) {                 console.log(error);             })     } } ...
