Hey Andy, Yes, that should work as well. I think the main issue with your code is that you aren't setting the attributeNames on the feature layer's new renderer. Check out the example below and see if you can get that working in your app. -Luke import QtQuick 2.3 import QtQuick.Controls 1.2 import ArcGIS.Runtime 10.25 import ArcGIS.Extras 1.0 ApplicationWindow {     id: appWindow     width: 800     height: 600     title: "SmallSymbolFix"     Map {         id: appMap         anchors.fill: parent         ArcGISTiledMapServiceLayer {             url: "http://services.arcgisonline.com/ArcGIS/rest/services/NatGeo_World_Map/MapServer"         }         FeatureLayer {             id: featLyr             featureTable: featureServiceTable         }     }     Button {         anchors {             left: parent.left             top: parent.top             margins: 15         }         text: "change renderer"         onClicked: {             var orig_info_List = featLyr.renderer.uniqueValues;             var new_renderer = ArcGISRuntime.createObject("UniqueValueRenderer", {attributeNames: featLyr.renderer.attributeNames});             for (var i = 0; i < orig_info_List.length; ++i) {                 //create the new symbol                 var symbol = orig_info_List.symbol;                 symbol.width = 40;                 symbol.height = 40;                 //create the new UniqueValueInfo                 var newInfo = ArcGISRuntime.createObject("UniqueValueInfo");                 newInfo = orig_info_List;                 newInfo.symbol = symbol;                 new_renderer.addValue(newInfo);             }             featLyr.renderer = new_renderer;         }     }     GeodatabaseFeatureServiceTable {         id: featureServiceTable         url: "http://sampleserver6.arcgisonline.com/arcgis/rest/services/DamageAssessment/FeatureServer/0"     } } ...

Hello, Unfortunately, Local Server is only supported with the C++ API and is only supported on Windows and Linux. -Luke ... View more

Francisco- That should work. libc++.so.1 is in that same directory. I'll suggest one more hack to try, but if this doesn't work, I suggest you contact Esri Support Services to troubleshoot it further, as there may be some back and forth involved. cd to ~/arcgis/runtime_sdk/qt10.2.5/sdk/linux/x64/lib (or wherever it was installed to) ln -s libc++.so.1 libc++.so # create symlink so we can explicitly link the clang runtime library in Qt project file, add: LIBS += -lc++' That should work, but what you were doing before should work as well. Thanks, Luke ... View more

The issue is an iOS specific issue that has to do with Qt's wrapping of OpenSSL. In order to workaround this, add the following inside of the ApplicationWindow - Component.onCompleted:{             ArcGISRuntime.identityManager.ignoreSslErrors = true; } ... View more

I think you may need to create a GP Package/Service from a GP Model or Python script in ArcGIS Desktop. This sounds like something you will likely need the Spatial Analyst extension for. To do this, you could use either Local Server or ArcGIS Server, and consume the service in your application using the Geoprocessor. Note that this workflow would only work with the C++ API (on Windows and Linux), as the QML API does not yet have Geoprocessor implemented. As far the actual script, you may need to string a few tools together. You could consider converting your x,y,density data (I assume these are points) to raster (Point to Raster—Help | ArcGIS for Desktop ). Then, feed the raster into Contour Spatial Analyst tool (Contour—Help | ArcGIS for Desktop ). From that, you could return a Feature Set to Qt, and displaying those features on the map. You could then do all of the symbology with the Qt SDK, using something like the Class Breaks Renderer. I hope this helps. As I'm not familiar with your data, it is hard to say if this is exactly what you need, but hopefully it can get you on the right track. Neither the C++ nor the QML API have spatial analyst functions built within it, so the GP Service route is what most people need to do for these types of workflows. Thanks! Luke ... View more

KK- ArcGISDynamicMapServiceLayer isn't the layer you want for editing. This type of layer is for retrieving images from a server, similar to ArcGISTiledMapServiceLayer. The difference between these 2 is that the dynamic layer can be dynamically changed on the server, whereas the tiled layer has pre-generated tiles stored on the server. If you are editing, you want to use the FeatureLayer and the GeodatabaseFeatureServiceTable/GeodatabaseFeatureTable. In MVC speak, the GeodatabaseFeatureTable is your model and the FeatureLayer is your view. In order to switch from online to offline, switch the feature table on the FeatureLayer from the GeodatabaseFeatureServiceTable to GeodatabaseFeatureTable. The "Local geodatabase editing" sample should show this concept. Thanks, Luke ... View more
