Hi,

I created the Application for Qt.

I want to use this App on offline, but I don't know how.

I want my app to look like this

 :similar to Navigation App, but there is no destination.

 :simple motion, using a Latitude and Longitude to move.

 :stand-alone Application. (It's never going to be online.)

 :can see the map, when launch the app. 

 :can move symbols even when offline.

 :the map is loaded from the local directory.

How can I create an App like this one? And What kind of license do I need?

If It can't, at least tell me how to load the map offline from the local directory and use Latitude and Longitude to display the symbols.

Thanks.

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 · Es... 

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/arc... 

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

Thanks for answer.

I can understand very well.

I'm going to figure out which way to do it.
