* UHI (Urban Heat Island effect)
*      Temperature of atmosphere
* Vegetation average
* Vegetation (yes/no))
* Bowen ratio (evaporation ratio): in the city a value of 3 is normal. For green that evaporates well or open water, a value of 0.4 is normal.  
* Wind speed


De  overlays are calculated by our cuda module.
The selectable modules are:
* [[DPRA Heat Module|DPRA Heat stress module]]. This module is more detailed and based on the 2019 {{Heat DPRA Report}}. It can generate multiple Heat Overlay [[Result types (Heat Overlay)|result types]] as child overlays;
* [[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.

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:
