How to request DTED offline using ArcGIS.Net SDK?

Question

Our application must perform some height calculations (and is not connected to the Internet), as a result, we need to determine the highest height for a given polygon. How can we query DTED offline using the ArcGIS.Net SDK?

Here is the little progress I made ...

Option 1 - Use Esri.ArcGISRuntime.Controls.FileElevationSource

So, to use FileElevationSource, it turns out that it must be associated with a SceneView. We used MapView, so I added to SceneVeiw and linked FileElevationSource

sceneView.Scene.Surface.Add(elevationSource);

When I'm tired of accessing the source of exaltation, I get AccessViolation

elevationSource.GetElevationAsync(location as MapPoint).Result

Option 2 - Some Ways to Use LocalServer

Doco states that ArcGIS Runtime LocalServer supports several raster formats, including DTED. Local-ArcGIS Runtime SDK for .NET raster server support.
Therefore, I used ArcMap to create a map package file with DTED files inside, but I don’t know how to use Local Sever to request a package file

Ultimately, we want:

• Upload multiple DTED files
• Request for a given lat / lon that the height at this point

Any help would be greatly appreciated!

Please note that we are using the ArcGIS.Net SDK v10.2.7

Answer 1

async . :

var result = await elevationSource.GetElevationAsync( MapPoint);
