Public Class Camera

Remarks

Both 2D and 3D views define and manage what is being displayed using a camera object. You can get the current camera for the view using the MapView.Camera property.

In 2D, the camera defines its viewing location using X and Y. The values are in the same units as those defined by the camera's SpatialReference. This will be the center point of the 2D view's extent. The viewing direction, or rotation, of the map is defined using the camera's Heading property. The camera's Scale property then defines how far the view is zoomed in or out, and the 2D view will be able to display content for that area. You can also get the extent from the view using the MapView.Extent property.

In 3D, the camera defines its viewing location using X, Y and Z. As with 2D, the values are stored in the same units as those defined by the camera's SpatialReference, with the additional possibility that XY units and Z units may be different. This will be the central position for the 3D view, as though a helicopter was hovering in that location. The viewing direction is defined by a combination of the Heading, Pitch, and Roll properties, which will rotate, tilt, and roll how the camera looks at the content around it, and the 3D view will be able to display content for the defined frustum.

Example

Rotate the map view

public Task<bool> RotateView(double heading)
{
  //Get the active map view.
  var mapView = MapView.Active;
  if (mapView == null)
    return Task.FromResult(false);

  //Get the camera for the view, adjust the heading and zoom to the new camera position.
  var camera = mapView.Camera;
  camera.Heading = heading;
  return mapView.ZoomToAsync(camera, TimeSpan.Zero);
}

// or use the synchronous method
public Task<bool> RotateViewAsync(double heading)
{
  return QueuedTask.Run(() =>
  {
    //Get the active map view.
    var mapView = MapView.Active;
    if (mapView == null)
      return false;

    //Get the camera for the view, adjust the heading and zoom to the new camera position.
    var camera = mapView.Camera;
    camera.Heading = heading;
    return mapView.ZoomTo(camera, TimeSpan.Zero);
  });
}
