The Heat Stress Overlay is an [[grid overlay|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 selectable modules are:

* [[UNESCO Heat Module|UNESCO Heat stress module]]. This module generates a simple heat stress overlay which visualizes the [[Pet_relative_result_type_(Heat_Overlay)|Relative Physiological equivalent temperature]] result type. It uses a different (and smaller) set of formula's to calculate Heat differences. It does not calculate the expected Physiological Equivalent Temperature.


====Overlay Legend====

The default colors of the overlay generally mean the following:
{{Heat_Module_buttons}}
* Red: Red indicates the hottest area's, compared to the surroundings.
{{clear}}
* 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.

Example of the DPRA heat stress overlay

The new Heat Stress Overlay module is in accordance with the 2019 DPRA Heat stress report.

Modules

In order to configure a Heat Stress Overlay, a module has to be selected. The module can be configured by opening the Heat Overlay Wizard.

The selectable modules are:
