Heat Stress Overlay

What the heat overlay is

Example of the heat stress overlay

The heat stress overlay is an Overlay which displays the average temperature deviation (positive or negative) in different colors for the project area, indicating transitions in temperatures, resulting in heat stress. The default colors of the overlay generally mean the following:

• Red: Red indicates the hottest area's, compared to the surroundings.
• Green: Green indicates not much deviation from the average temperature deviation.
• Blue: Blue indicates the coolest area's, compared to the surroundings.

It is possible to change the colors of the overlay by editing the Legend in the Legend tab of the overlay.

Additional information displayed in hover panel

Hover panel displays additional information

The hover panel gives additional information when clicking in the map when the overlay is active. The additional information includes the terrain types, height and the average temperature deviation on the clicked location in °C.

Calculation Model

Because the Heat Overlay is directly linked to the Heat Stress indicator, it is currently not possible to load this Heat overlay separately. To activate the Heat overlay in you project, please see the documentation about Adding/removing indicators.
