Natural Risk Prevention Plan for Avalanches in Chamonix-Mont-Blanc

COVADIS data standard for risk prevention plans provides specifications for digital storage of geographical data from French Risk Prevention Plans (PPRs). The dataset for Chamonix-Mont-Blanc avalanches contains regulatory zoning, hazard intensity mapping, and identified issues, as defined by the Act of 2 February 1995.
