Hi @FatmaAkdemir, you can do this in Runtime using the 2D ExportTilesTask example but be aware that you won't see a basemap rendered for the elevation surface so you may need a different way to orient yourself so that you can take the area offline. Also be aware that Esri tiled services have a maximum number of tiles which can be requested when taking data offline so you may need to select a small area to get this to work. You also need to be authenticated to export tiles.   Once you have the tiles exported as a tpk you can use this to create a TileCache object which you supply to the elevation sources for your scene. Here is some example C++ code that I used to try this part out:   auto tpk = new TileCache("~\\tpks\\elevation_source.tpk", this); ArcGISTiledElevationSource* elevationSource = new ArcGISTiledElevationSource(tpk, this); connect(tpk, &TileCache::doneLoading, this, [tpk, this](Error e) {   auto cc = new OrbitLocationCameraController(tpk->fullExtent().center(), 500, this); m_sceneView->setCameraController(cc); m_sceneView->arcGISScene()->baseSurface()->setElevationExaggeration(8); }); // add the elevation source to the scene to display elevation m_scene->baseSurface()->elevationSources()->append(elevationSource);   I hope that helps.   Luke  ...

Hi @FatmaAkdemir    If you want to download an elevation source from that service you will need to make use of the for export version which supports exporting tiles. In terms of high resolution, that would depend on your particular use case - that data set includes tiles to LOD level 16:  Level ID: 16 [ Start Tile, End Tile ] Resolution: 2.388657133974685 Scale: 9027.977411 If you want to export the data, there are a couple of options:   Use the ExportTileCacheTask with the Runtime API. This will allow you to create a tpk which you can programmatically add to your Scene as an elevation source.   Use ArcGIS Pro with the "Download map" option to create a MobileScenePackage: 1. Make sure you are logged into AGOL 2. Create a new map 3. Add data by path > https://tiledbasemaps.arcgis.com/arcgis/rest/services/WorldElevation3D/Terrain3D/ImageServer 4. Zoom to desired area > Click Map Tab > Click Download Map 5. Select desired scales > click download 6. The layer gets added to the map so go ahead and copy it to a new global scene 7. Drag the layer into the ground elevation surface and remove the service 8. Remove any other services and create the mobile scene package   I hope that helps,   Luke ... View more

Hi @rsharma - if your Map is not yet loaded (for example you read it directly from a MobileMapPackage already on your device) you should be able to use void Map::setInitialViewpoint(const Esri::ArcGISRuntime::Viewpoint &viewpoint) before you set it on the MapView.   Another approach would be to use https://developers.arcgis.com/qt/latest/cpp/api-reference/esri-arcgisruntime-mapview.html or similar to set the position directly on the view.   Hope that helps,   Luke ...

Hi @FatmaAkdemir we do have support for offline data using our MobileScenePackage format which you can author in ArcGIS Pro. You can also build up an offline scene yourself using offline data-sets such as a tile package (.tpk), scene layer package (.slpk). Here's an example of using a MobileScenePackage: https://github.com/Esri/arcgis-runtime-samples-qt/tree/master/ArcGISRuntimeSDKQt_CppSamples/Scenes/OpenMobileScenePackage I hope that helps, Luke  ...

Hi @FatmaAkdemir    One thing you could try is to use a Renderer with your GraphicsOverlay which will use the same symbol for all Graphics - rather than creating a new symbol for each point. This sample shows an example of that workflow. You could use an attribute on the points to choose a different color if required - see this example for that kind of approach. If rendering individual points is not working well - you could also experiment with creating a raster dataset for your radar points. You can use a number of raster formats with the RasterLayer API. ... View more

Hi Wada Takumi‌, If you need to display an Offline Map, one way to do it is to create a MobileMapPackage in ArcGISPro which contains the base map and features that you need. You can then open the Mobile Map Package in Runtime - see this sample for an example of that workflow: arcgis-runtime-samples-qt/ArcGISRuntimeSDKQt_CppSamples/Maps/OpenMobileMap_MapPackage at master · Esri/arcgis-runtime-sa…  If you don't have access to ArcGIS Pro then you can download an offline map from ArcGIS Online (or your own portal) - see this sample for an example of that approach: arcgis-runtime-samples-qt/ArcGISRuntimeSDKQt_CppSamples/Maps/GenerateOfflineMap at master · Esri/arcgis-runtime-samples-…  To display positions using Latitude and Longitude you can create a Point supplying an x, y position at a SpatialReference of wgs84 (note the static method that will create this for you). Also take care that you pass Latitude and Longitude in the right order: Latitude corresponds to the "y" axis and Longitude corresponds to the "x" axis. This sample gives an example of adding graphics using lat/long: arcgis-runtime-samples-qt/GOSymbols.cpp at master · Esri/arcgis-runtime-samples-qt · GitHub  I hope that helps, Luke ... View more

One other thing which may be worth trying is to make sure that individual graphics are removed when you loop round and call  glm->removeOne(graphic); The call to remove a Graphic is asynchronous and you should wait for the graphicRemoved signal before removing the next. I'm not sure if that is affecting the work-flow that you use here but it may be worth investigation. ... View more

Hi Norbert, I hope you're well. We'll take a look at your repro to try and understand what is going on. In the meantime, one thing which may be of use is to try and avoid creating a new SimpleMarkerSymbol for each Graphic that you allocate: Esri::ArcGISRuntime::SimpleMarkerSymbol *sms = new Esri::ArcGISRuntime::SimpleMarkerSymbol(Esri::ArcGISRuntime::SimpleMarkerSymbolStyle::Circle, QColor("red"), 10, graphic); graphic->setSymbol(sms); If you can create a SimpleRenderer  for the GraphicsOverlay instead, then each Graphic in that overlay will get the same symbol without having to allocate additional memory. This should be a more efficient workflow in general - this sample should give you an idea of how to use that API arcgis-runtime-samples-qt/ArcGISRuntimeSDKQt_CppSamples/DisplayInformation/Simple_Renderer at master · Esri/arcgis-runti… . I can see that this is a simplified repro project so if you are already doing that in the real example please ignore. Luke ... View more

Hi Rob - does  the map render correctly? e.g. do you see the OpenStreetmap basemap you set above? If it's rendering then the map is loading. One possibility could be that you connect to the signal after loading is complete. The loading cycle will be kicked off as soon as you call m_mapView->setMap(m_map);. Can you make sure you set up the connection as soon as you construct the map? Another observation is that you are setting the initial viewpoint for the map after you set it on the mapView (m_map->setInitialViewpoint(viewpoint);). For this to have an affect you need to do that before passing the map to the mapView as well. ... View more

Hi Rob - can you confirm the map is loaded before you make the screenToLocation call? You can use the Map's doneLoading or loadStatusChanged signals to wait for that. ... View more

Hi Rob, To do this you would make use of the MapGraphicsViews screenToLocation function - passing it the coordinates from your view. The upper left corner would be 0,0 in view coordinates and you should be able to get the lower right by taking the width/height of your map view. This sample shows a different use of that functionality (reacting to a user clicking on the screen) but tghe principle is the same. ... View more
