The utility of forest attribute maps for automated Avalanche Terrain Exposure Scale (ATES) modelling
Fatalities associated with recreational activities occur every year as a result of snow avalanches. Terrain classification systems, such as the Avalanche Terrain Exposure Scale (ATES) are designed to provide guidance for safe route finding and this system has been automated (AutoATES).

Fatalities associated with recreational activities occur every year as a result of snow avalanches. Terrain classification systems, such as the Avalanche Terrain Exposure Scale (ATES) are designed to provide guidance for safe route finding and this system has been automated (AutoATES). ATES classifies terrain into the three classes simple, challenging, and complex. Forests can provide some protection from avalanches, and these can be incorporated into avalanche hazard models. The objective of this study was to map relevant forest attributes (stem density and canopy cover) based on National Forest Inventory and remote sensing data and, subsequently, use these forest attributes as input to the AutoATES model to improve avalanche hazard maps. We predicted stem density with species-specific mixed-effects models and directly calculated canopy cover using airborne laser scanning data in a 20 Mha study area ranging from the arctic circle to southern Norway.
