If the observer position is uncertain, let the user move the observer around.

If the atmospheric refraction is uncertain, let the user modify its value with a continuous slider.

If the tree heights are estimated from terrain types as in Trees as Obstacles, you can let the user edit the table of estimates (perhaps with a continuous slider for the tree height of each forest type). Remember that since the global cache is used, the Operator.FlushCache method must be called before the view is updated.

If the elevation data are uncertain, you can add a raster with random errors to your elevation raster (you must make a custom operator that creates the random raster). Again, since the global cache is used, the Operator.FlushCache method must be called before the View is updated.
