Datasets
This representation is derived from the swissBATHY3D data and allows the visualization of the depth and lakebed relief of Swiss lakes. A hillshade is derived from the elevation model by calculating the exposure of the surface to sunlight at a certain angle. The calculated angle of the sun for the swissBATHY3D Hillshade is at azimuth 315° (northwest), at a vertical angle of 45°.
