I have 2 feature datasets in a .gdb (CNMS_Inventory and CNMS_Inventory_Albers). I set the dataset for  CNMS_Inventory  to 4269(NAD83) when I created it and it contains a feature class called  S_Studies_County_Intersect_Merged . My goal is to basically change the projection of  S_Studies_County_Intersect_Merged  to  North America Albers Equal Area Conic  and write the output to the dataset (in the same gdb) called  CNMS_Inventory_Albers  (which was set to  North America Albers Equal Area Conic ). I first tried just using  CopyFeatures  but it threw an error: cnms_inventory = os.path.join(all_regions_gdb, "CNMS_Inventory") new_studs = os.path.join(cnms_inventory,"S_Studies_County_Intersect_Merged") albers_ds = os.path.join(all_regions_gdb, "CNMS_Inventory_Albers") albers_studs = os.path.join(albers_ds, "S_Studies_Ln_Merge_Albers") albers_unmapped = os.path.join(albers_ds, "S_Unmapped_Ln_Merge_Albers") arcpy.CopyFeatures_management(new_studs, albers_studs) Error Traceback: ExecuteErrorTraceback (most recent call last) in () 2 albers_studs = os.path.join(albers_ds, "S_Studies_Ln_Merge_Albers") 3 albers_unmapped = os.path.join(albers_ds, "S_Unmapped_Ln_Merge_Albers") ----> 4 arcpy.CopyFeatures_management(new_studs, albers_studs) C:\Program Files (x86)\ArcGIS\Desktop10.5\arcpy\arcpy\management.py in CopyFeatures(in_features, out_feature_class, config_keyword, spatial_grid_1, spatial_grid_2, spatial_grid_3) 2584 return retval 2585 except Exception as e: -> 2586 raise e 2587 2588 @gptooldoc('DeleteFeatures_management', None) ExecuteError: ERROR 000224: Cannot insert features Failed to execute (CopyFeatures). I figured that this maybe due to the fact that the output feature, new_studs ( S_Studies_Ln_Merge_Albers ) needs to be projected into  Albers  first (I was thinking I maybe cannot just write a NAD83 projected feature to an Albers projected dataset). So I tried the following which gives be another error: sr = arcpy.SpatialReference(4269) projection = arcpy.SpatialReference('North America Albers Equal Area Conic') arcpy.Project_management(new_studs, albers_studs, out_coor_system=projection, in_coor_system=coord_sys) ExecuteError: ERROR 000210: Cannot create output T:\CCSI\TECH\FEMA\Datasets\CNMS\FY18Q3\CNMS_AllRegions_FY18Q3.gdb\S_Studies_Ln_Merge_Albers Failed to execute (Project). Looking at this error, it seems like  Project  is trying to write my output to  "T:\CCSI\TECH\FEMA\Datasets\CNMS\FY18Q3\CNMS_AllRegions_FY18Q3.gdb\S_Studies_Ln_Merge_Albers"  instead of  "T:\\CCSI\\TECH\\FEMA\\Datasets\\CNMS\\FY18Q3\\CNMS_AllRegions_FY18Q3.gdb\\CNMS_Inventory_Albers\\S_Studies_Ln_Merge_Albers" , which basically leaves out the feature dataset  CNMS_Inventory_Albers . Can anyone see where I am going wrong here or how I can fix this? ... View more

I am using  arcpy  to merge multiple feature classes from a list of feature classes. They all have the same fields. Let's say they all have the  fields = ['CO_FIPS', 'MILES', 'FLOOD_ZONE', 'VALID', 'REGION'] . However, I only want to include 'CO_FIPS', 'MILES', and 'FLOOD_ZONE' in the output merged feature class. It seems I need to use  field mapping  to limit the fields in my output, but I am not 100% how to do that: working_dir = r"C:\Projects\MyProj\stream_lines.gdb" arcpy.env.workspace = working_dir s_studies_for_merge = ['stream1', 'stream2', 'stream3'] fieldMappings = arcpy.FieldMappings() merged_output = os.path.join(working_dir, "AllStreams") fieldMappings.addTable('stream1') for field in fieldMappings.fields: if field.name not in ['CO_FIPS', 'MILES', 'FLOOD_ZONE']: fieldMappings.removeFieldMap(fieldMappings.findFieldMapIndex(field.name)) arcpy.Merge_management(s_studies_for_merge, merged_output, fieldMappings) My confusion is mainly that most examples show only 2 features being merged and that the mapping involves settings that I don't need for certain fields. I only want to exclude the fields I don't want and keep the fields I do. What do I need to do here? ... View more

I am  "dijit/TooltipDialog"  and  "dijit/popup"  in my web mapping app on a few geojson layers.      dialog = new TooltipDialog({ id: "tooltipDialog", style: "position: above; width: 175px; font: normal normal normal 10pt Helvetica;z-index:100" }); dialog.startup(); .... _getGeoJson: function (geojson) { // Check data if (geojson.type !== "FeatureCollection" || !geojson.features) { console.error("GeoJsonLayer Error: Invalid GeoJSON FeatureCollection. Check url or data structure."); return; } // Convert GeoJSON to ArcGIS JSON var arcgisJson = this._terraformerConverter(geojson); // Add graphics to layer this._addGraphics(arcgisJson); //Add tooltip on mouse-over this.on("mouse-over", function (evt) { var content = esriLang.substitute(evt.graphic.attributes); dialog.setContent(content); domStyle.set(dialog.domNode, "opacity", 0.9); dijitPopup.open({     popup: dialog, x: evt.pageX, y: evt.pageY }); }); //Remove tooltip on mouse-out this.on("mouse-out", function (evt) { //map.graphics.clear(); dijitPopup.close(dialog); }); } All of this works fine...if the browser console (the developer's console) is open. No problems, tooltips display and disappear as you mouse over or mouse out of the respective layers. However, if the console is not open, there is a 10-30 second delay before the tooltips will appear and if the extent is changed, or you pan, or you zoom in/out, the delay also occurs. No bugs are being thrown and, like I said, it doesn't occur when the browser console is open, so its kinda hard to debug. Note: I am running this in an  ASP.Net  app from my local (its not on a server yet) using  arcGIS Javascript API 3.29  and related dependencies. Why would this occur and how might I resolve it? ...

I have an API that uses Basic Authentication (Username, Password). I am trying to use this in an  esriRequest  to pull back the  JSON  data object from the  GET  request. To test this (and potentially avoid CORS issues), I am running this on my localhost (IIS). I have already set my  IIS Default WebSite HTTP Response Headers  to  Access-Control-Allow-Origin: '*' . However, I am still getting the following error in my  esriRequest  : Access to XMLHttpRequest at 'https://ria.azurewebsites.net/api/ria/event?Username=myUsername&Password=myPassword' from origin 'http://localhost' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. This error gets thrown in both Chrome and Firefox.I even tried adding  withCredentials: true  to my request, but it then throws an additional error: Cross-Origin Read Blocking (CORB) blocked cross-origin response with MIME type application/json. At the top of my code, I have also added:  esriConfig.defaults.io.corsEnabledServers.push("ria.azurewebsites.net"); , which has resolved this CORS issue for other APIs in my application, but not this one. I have tried several configurations, but my current code uses a  precallback function  and  .setRequestPreCallback()  method. As you can see in the commented out attributes, I've also tried to pass 'Username' and 'Password' as content too. I have tested the general  GET  Request in  Swagger UI  and it comes back just fine. Is there something I am missing here; something else I need to do in order for this to work?: function floodCallbackFunction(ioArgs){    if (ioArgs.url.indexOf("https://ria.azurewebsites.net") > -1) {       ioArgs.headers.Username = "myUsername";       ioArgs.headers.Password = "myPassword"; // add custom headers    }    return ioArgs; } .... esriRequest.setRequestPreCallback(floodCallbackFunction); var evnts; var eventRequest = esriRequest({    withCredentials: true, url: "https://ria.azurewebsites.net/api/ria/event",    content: { // "Username": "myUsername", // "Password": "myPassword"    },    dataType:"jsonp",    handleAs: "json"});    eventRequest.then(function(resp) {       evnts = resp;       console.log(evnts);       console.log("Success: ", evnts);    }, function(error) {       console.log("Error: ", error.message); }); ...

I have a simple map service API that serves a grid feature and I want to grab an attribute ("Grid_Cell2") that has the grid cell name when the user clicks a button. The grid feature has start and end points (x, y) for each cell and a field called "Grid_Cell2" which is basically the grid cell name (ex: "Grid_Cell49_19"). I am already capturing my x, y for the mouse click on the map in my application. The examples I have seen for IdentifyTask and IdentifyParameters generally show the .executefor the IdentifyTask method being launched when the user clicks on the map (ex:map.on("click", executeIdentifyTask);`) and then populating a popup. I only want to grab the desired feature based on the users x, y (which I have already captured in a variable) when the user clicks the button. Assume I have already added the required module and function and initialized the function at the top: document.getElementById("btnGetInterval").onclick = function () { var point = additionalInfo["pointGeomOfInterest"]; //this is an x, y coordinate captured earlier in my code from the user's mouse click on the map identifyTask = new IdentifyTask(grid_url); identifyParams = new IdentifyParameters(); identifyParams.geometry = point; identifyParams.returnGeometry = false; //I don't want to return any geometry identifyParams.layerOption = IdentifyParameters.LAYER_OPTION_ALL; //Not sure about this. I just want to return the one feature for the grid cell whose boundaries my user's mouse click (x, y) falls within....‍‍‍‍‍‍‍ From here, I'm honestly not sure where to go; I assume I want to use a .execute statement but I am not sure how the `IdentifyParameters come into play. I also may need an empty var/array/list to hold the returned value (["Grid_Cell2"]). Any suggestions here? ... View more
