UIBK Avalanche Dataset

Each photograph in the dataset was assigned to one of four categories: glide, loose, slab, or none. These labels refer to the different avalanche release mechanisms: glide, loose-snow, and slab, with none indicating the absence of avalanches.

In addition, avalanche experts outlined each visible avalanche with a polygonal bounding box and assigned it a single label of glide, loose, or slab. The photographs were taken in the field in the winters of 2000/2001 - 2021/2022 and each image has the date and approximate location at which it was taken in the image name. Most photographs in the dataset were taken from the ground: additional images from low-flying helicopters were included only if the annotators deemed that they could feasibly have been taken by webcams.
