New slope class

After discussion with the WSL Institute for Snow and Avalanche Research SLF and the Swiss Alpine Club SAC, swisstopo has introduced a new class for slopes exceeding 50° in the slope classes layer. The aim is to improve readability. The changes are visible immediately in the slope classes layer on map.geo.admin.ch and in the swisstopo app.
