Show height in mouse position

I need to show height above the sea level in mouse cursor point on the surface. How can i get it?

My mouse cursor handler (i display cursor coordinates, but the third parameter should be height) :

private async void MySceneView_MouseMove(object sender, MouseEventArgs e)
{

if (MySceneView.GetCurrentViewpoint(ViewpointType.BoundingGeometry) == null)
return;

System.Windows.Point screenPoint = e.GetPosition(MySceneView);
MapPoint mapPoint = new MapPoint(0,0,0);

mapPoint = await MySceneView.ScreenToLocationAsync(screenPoint);

MapCoordsTextBlock.Text = string.Format("Map Coords: X = {0}, Y = {1}, Z = {2}",
Math.Round(mapPoint.X, 4), Math.Round(mapPoint.Y, 4), "I need height in meteres here");

}

And just in case my scene initialization (i use geotiff data for 3d relief) :

private async void CreateNewScene()
{
Scene newScene = new Scene(Basemap.CreateImagery());

RasterElevationSource elevationSource = new RasterElevationSource(new[]@"D:\Programms\ArcGis

\14072020geotiff\DEM_geotiff\alwdgg.tif" });
await elevationSource.LoadAsync();

Surface elevationSurface = new Surface();
elevationSurface.ElevationSources.Add(elevationSource);
await elevationSurface.LoadAsync();

newScene.BaseSurface = elevationSurface;
Scene = newScene;
await Scene.BaseSurface.LoadAsync();
}
