swissALTIRegio multidirectional Hillshade

The hillshade is derived from the digital elevation model swissALTIRegio. It illustrates the surface relief of Switzerland, the Principality of Liechtenstein and the neighbouring regions. A hillshade is derived from the elevation model by calculating the exposure of the surface to sunlight at a certain or several angles. The swissALTIRegio hillshade uses a multidirectional method that combines light from 6 different sources (sun's positions). The average sun's position is located to the northwest.
