// .NAME vtkGeoView - A 3D geospatial view.
//
// .SECTION Description
// vtkGeoView is a 3D globe view. The globe may contain a multi-resolution
// geometry source (vtkGeoTerrain), multiple multi-resolution image sources
// (vtkGeoAlignedImageRepresentation), as well as other representations such
// as vtkRenderedGraphRepresentation. At a minimum, the view must have a terrain
// and one image representation. The view uses vtkGeoInteractorStyle to orbit,
// zoom, and tilt the view, and contains a vtkCompassWidget for manipulating
// the camera.
//
// Each terrain or image representation contains a vtkGeoSource subclass which
// generates geometry or imagery at multiple resolutions. As the camera
// position changes, the terrain and/or image representations may ask its
// vtkGeoSource to refine the geometry. This refinement is performed on a
// separate thread, and the data is added to the view when it becomes available.
