Description

This dataset contains the data used and collected to investigate the reliability of avalanche size estimates and avalanche outlines (see related publications). Namely this is

Avalanche size estimates

  • the 10 pictures depicting avalanches
  • the survey results from the 170 participants

Avalanche outlines mapped from oblique photographs

  • the pictures of the six avalanches
  • the avalanche outlines mapped by the 10 participants
  • the reference mapped from the georeferenced photographs

Avalanche outlines from remotely-sensed imagery

  • the orthophotos in the four different resolutions (2m, 1m, 50cm, 25cm)
  • the area of interest (AoI) delimiting the research area
  • the avalanche mappings in each resolution for all five participants
  • the shade masks used to separate illuminated and shaded areas

The acquisition of the orthophotos has been partially supported by the Swiss National Science Foundation (SNF; Grant N°200021_172800).
