Just a suggestion but you could also initialize the config object right at the start and then just assign the values to it. This just reduces the number of variables used and keeps things clean:     // app configuration      var config = {         mapOptions: {             showAttribution: false,             sliderStyle: "small",             extent: initialExtent,             logo: false,             sliderPosition: "bottom-right"         },          signLayerUrl: undefined,         supportLayerUrl: undefined     };          restEndPoint = "http://maps.decaturil.gov/arcgis/rest/services/test/StreetSignTest/FeatureServer/";     // Get the id of a layer     var requestHandle = esriRequest({         url: restEndPoint,         content: { f: 'json' },         handleAs: "json"     });     requestHandle.then(function (lyrJSON, io) {         for (var i = 0; i < lyrJSON.layers.length; i++) {             if (lyrJSON.layers.name == "Support") {                  config.supportLayerUrl = restEndPoint + lyrJSON.layers.id;             }             if (lyrJSON.layers.name == "Sign") {                 config.signLayerUrl = restEndPoint + lyrJSON.layers.id;             }         }         initMap();     }) EDIT - updated with the final function parenthesis and restEndPoint variable as Chris pointed out (just in case anyone copies the code block). ...

Not sure of the hard limits but I have seen a map document used by a large local government with over 500 layers in it. This was used to publish a map service. Not ideal in my opinion for a range of reasons but it worked for them. The main issue that you will face as you add more map layers is the rendering time (if they are turned on). Also as you add more layers it becomes increasingly difficult to create unique symbology to define features and there is also a limit on how much information a user can process in their head at once ...

Good catch - I hadn't seen that post. ... View more

SHAPE@XY for a line feature will return the feature centroid. You will need to use SHAPE@ and then locate the vertex point on the polyline to update. These pages have more detail: Reading geometries - ArcGIS Help (10.2, 10.2.1, and 10.2.2) Writing geometries - ArcGIS Help (10.2, 10.2.1, and 10.2.2) ... View more

I haven't touched avenue for a very long time but the second number is most likely scale. The Double data type has precision and scale. This page has some more information - ArcGIS Help (10.2, 10.2.1, and 10.2.2) ... View more

The above approach should work - see this live example: ESRI Service Test Note that I also add your server in the esri.config so you don't get other CORS errors: esri.config.defaults.io.corsEnabledServers.push("maps.decaturil.gov"); ... View more

You could use a REST API Query with the ObjectId as a parameter - ArcGIS REST API ... View more

the graduation should be green if it's negative and red if it's positive, so a negative vs positive change can be discerned. Pick the color ramp you want in the layer properties: You can also double click on any color patch and change it manually to a different color. Also a minor detail, but a state like Oklahoma should be on landscape view. You can change the map to Landscape in File > Page and Print setup. ... View more

Have you checked that the shapefile has a spatial reference assigned to it? A shapefile can happily exist without ever being assigned a spatial reference. This would explain why you get null as a result of the getSpatialReference() call. ... View more

As Dan astutely points out, the values are left aligned indicating that the data is text and not numeric. This has most likely happened when it was imported from Excel. You can quickly check the field type by right-clicking on the field header in the attribute table and selecting ‘Properties’. If all of the values in the field are numeric you can easily convert them back to numbers: 1. Add a new field to your data: 2. Calculate the field values from your text field: This should bring all of your values across into the new field and you should notice that the values are right-aligned numbers. 3. Now try to apply your symbology again and the new numeric field should appear as a value option. ... View more

This was my initial thought as well. However, I don't think it will work in this case if the split is not completed. The only way to do this is to set up labelling as Jayanta suggests, start an edit session, split the polygon, check the area and undo the split if required. ... View more

I haven't tried this but you could loop through the featureInfos array and only process the Polygon type. var kmlLayer = new KMLLayer( ... );   var featureInfos = kmlLayer.folders[0].featureInfos;   array.forEach(featureInfos,function(info){     // Test if info.type == Polygon       // if it is a polygon do something with the feature - like add it to a graphics layer   }); ...

This project might be helpful ESRI_Panoramio_Web The website links are dead but there is a Code Attachment that has a dojox.rpc.Service with an SMD file to connect to the Panoramio API. You may be able to use it out of the box or modify it to suit. Otherwise the Panoramio API has some details on making requests using an extent. You could then convert the results into ESRI JS graphics. ... View more
