I am running ArcMap 10.2 and have been trying to complete a fairly large viewshed analysis and have chosen to use the visibility tool in order to be able to produce an optional above-ground-level (AGL) layer which will be the focus of further analysis. The visibility is from a layer consisting of 2 points and the raster is a DSM. I have run several repetitions of this tool (both 3D Analyst & Spatial Analyst) and every time the process completes successfully producing a viable viewshed, but there is never any AGL to be found. There are no errors accompanying the completion of the tool either. Why would this be? How do I get the tool to produce an AGL? I have tried using only one viewer point as opposed to two without any difference in the outcome. Thanks, Colin ... View more

Greetings, I'm interested in passing a geometry object with certain attributes to an exposed feature class for committed edits. Essentially, I want to manually create a new feature without the template pane or editor widget. The geometry and attributes are both pre-defined, and the user just needs to select one pair from a group and push an "Add to Geodatabase" button. I'm reading through the documentation and I can't see a clear way to do this. I see that if I don't want the pane or widget, then I need to use a geometry service, but I don't see a "create feature" method, or something that accepts a geometry object or attributes. Thanks for the help, Colin ... View more

Greetings, I'm implementing popup windows because I like their style, zoom function, and maximize window option... my app, though, has a logo and drop down menu in two corners... when I maximize my popup window, the logo floats above, as does the button, blocking the minimize and exit commands of the popup. Is there any way of setting the z-value of the popup? Or is there a way to alter the maximum dimensions? Thanks, DR ... View more

Greetings, The zoom slider that shows up in my map by default has two little boxes, with no "slider" in between them... see the attached screenshot for a visual. How can I get the normal zoom slider that I see on all of the samples? Thanks, DR ... View more

Greetings, I just figured out a technique to output the fields of many different layers (with different fields) into a datagrid from an info query... it seems to have decent performance, and so I thought I'd share it here, since I couldn't find a similar sample around. Also, it could be that this isn't the best way to go about this, and someone might have some critique. I set most of the identity parameters up when I construct my map service, as well setup an event handler for when a user clicks the map. When constructing the structure for the datagrid, I specify certain fields I want to hide from the user, as well as ensure a wide column for the "Notes" field, which I know typically contains large strings (Dojo does not recommend width="auto", as it isn't fully supported and can cause some funky errors). Further down the line, I check to see if the datagrid exists, and if it does, can just update the structure (to accommodate new fields) and store. Importantly, this is setup for identifying a single feature... to alter it for multiple features, I might just remove the allItems.slice(0,1) and tweak the graphics section to handle multiple geometries. With the single feature in mind, I added the grid.canSort function at the end to disable the column sorting... without this little bit, the column headers add an annoying little arrow on top of the label when clicked that throws the layout off a bit. Hope this helps some folks.  function constructLayers(){   fLayers = new esri.layers.ArcGISDynamicMapServiceLayer("http://server/ArcGIS/rest/services/features/MapServer");   allLayers.push({layer:fLayers,title:'Features'});   gsvc = new esri.tasks.GeometryService("http://server/ArcGIS/rest/services/Geometry/GeometryServer");   dojo.connect(map, "onClick", executeIdentityTask);     identityTask = new esri.tasks.IdentifyTask("http://server/ArcGIS/rest/services/features/MapServer");   identityParams = new esri.tasks.IdentifyParameters();   identityParams.layerOption = esri.tasks.IdentifyParameters.LAYER_OPTION_TOP;   identityParams.tolerance = 6;   identityParams.width = map.width;   identityParams.height = map.height;   identityParams.returnGeometry = true; } function executeIdentityTask(evt){   map.graphics.clear();     identityParams.mapExtent = map.extent;   identityParams.geometry = evt.mapPoint;   identityTask.execute(identityParams, function(layerInfo){    displayInfo(layerInfo);   }); } function displayInfo(layerInfo){   /* Graphics */   var symbol = new esri.symbol.SimpleMarkerSymbol();   var graphic = layerInfo[0].feature;   graphic.setSymbol(symbol);   map.graphics.add(graphic);     /* Datagrid */   var allItems = dojo.map(layerInfo, function(layerInfo){    return layerInfo.feature.attributes;   });     var items = allItems.slice(0, 1);     var data = {    items: items   };     var currentStore = new dojo.data.ItemFileReadStore({    data: data   });     var currentLayout = []   for (fieldName in items[0]) {    if (fieldName == "OBJECTID"||fieldName == "ROWGUID"|| fieldName == "Shape"){     var addField = {     field: fieldName, hidden: true     };     currentLayout.push(addField);    }    else if (fieldName == "NOTES"){     var addField = {     field: fieldName, width: "500px"     };     currentLayout.push(addField);    }    else{     var addField = {     field: fieldName     };     currentLayout.push(addField);    }   }     if (grid === null || grid === undefined) {    /* Create Grid */    grid = new dojox.grid.DataGrid({     store: currentStore,     structure: currentLayout    }, document.createElement('div'));       dojo.byId("gridPane").appendChild(grid.domNode);    grid.startup();   }   else {    /* Update Grid */    grid.setStructure(currentLayout);    grid.setStore(currentStore);   }     grid.canSort = function(){    return false;   } } And to avoid identifying features in layers that are "visible" but turned off, I include a... identityParams.layerIds = visible; ...line in both the portion of my code that produces a layer checklist ("visible" being an array of those layers that are turned on), and the portion that updates the visibility. See examples of returning a visible layers array in the sample here... http://help.arcgis.com/en/webapi/javascript/arcgis/help/jssamples/map_dynamiclayerlist.html ... View more
