object Hillshade

Computes Hillshade (shaded relief) from a raster.

The resulting raster will be a shaded relief map (a hill shading) based on the sun altitude, azimuth, and the z factor. The z factor is a conversion factor from map units to elevation units.

Returns a raster of ShortConstantNoDataCellType.

This operation uses Horn's method for computing hill shading.

If Hillshade operations encounters NoData in its neighborhood, that neighborhood cell well be treated as having the same elevation as the focal cell.
