aval-e/DeepLab4Avalanches: Code to automatically identify avalanches in SPOT 6/7 imagery (v1.0.0) Patrick Barton and Elisabeth D. Hafner

Short summary
Knowing where avalanches occur is very important information for several disciplines, for example avalanche warning, hazard zonation and risk management. Satellite imagery can provide such data systematically over large regions. In our work we propose a machine learning model to automate the time-consuming manual mapping. Additionally, we investigate expert agreement for manual avalanche mapping, showing that our network is equally as good as the experts in identifying avalanches.
