This document describes the functionality of the Avalanche Hazard layer of the Map view of the InfoEx report.

The goal of the Avalanche Hazard map layer is to provide a spatial overview of all the hazard assessments submitted in the time period of the current report.

Layout

Fig. 2: Detail of weather observation shown in map view of InfoEx report.

The hazard assessment map layer shows the locations of all the hazard assessments included in the current report (Fig. 1). They are displayed at the centre point of the location associated with the hazard assessment.

The icons of the hazard assessments are shown for each rating submitted by elevation band Alpine/Treeline/Below Treeline. The color for each band represents the rating:

• 1 - Green
• 2 - Yellow
• 3 - Orange
• 4 - Red
• 5 - Black

The currently supported weather parameters are (Fig. 2):

Tmin	Blue label	Lowest minimum temperature recorded at weather sites by this operation during the time period of report.
Tmax	Red label	Highest maximum temperature recorded at weather sites by this operation during the time period of report.
WX Label	White label	Name and elevation of weather site.

• Click on a weather observation parameter in the layer hierarchy panel to directly zoom the map to the area that has weather observations of the particular type.
• Click on the check box next to the observation parameters in the layer hierarchy panel to show/hide the particular observation parameter in the map.
