The Avalanche Terrain Exposure Scale (ATES) is a terrain classification system developed by Parks Canada to to better communicate the complexities and risks of traveling in avalanche prone terrain (Statham et al. 2006). Campbell and Gould (2013) proposed a model for GIS assisted classification using ATES. Larsen et al., (2020) extended this model, and developed an automated ATES, available nationwide in Norway. The aims of this presentation are to present the current and ongoing development towards an automated ATES model, which can uniformly be applied to avalanche terrain worldwide.The benefits of this approach are to standardize mapping of avalanche terrain across large spatial extents, and increase efficiencies at larger scales.
