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).
