  • municipality
  • start zone point latitude
  • start zone point longitude
  • start zone point accuracy (in meters)
  • start zone point elevation (in meteres above sea level)
  • slope aspect (main orientation of start zone)
  • slope inclination (in degree, steepest point within start zone)
  • forecasted avalanche danger level 1 (first danger)
  • forecasted avalanche danger level 2 (second danger)
  • accident within the core zone (most dangerous aspect and elevation as mentioned in the forecast)
