The new Heat Stress [[Overlay]] module is in accordance with the 2019 {{Heat DPRA Report}}. 


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.

De overlay is te vinden als laatste knop.
Hier bevinden zich meerdere overlays:
1. De Pet kaart (gevoelstemperatuur)
2. Foliage (boomhoogte kaart)
3. Shade (slagschaduwkaart)
4. Average Sky View
5. Sky view (percentage lucht t.o.v. totaal zicht),
6. UHI (Urban heat island effect)
7. Temperatuur atmosphere
8. Vegetation avg
9. Vegetation (ja / nee)
10. Bowen ratio (verdampings ratio)
11. Wind speed (wordt nog aan gewerkt)


De  overlays worden door onze cuda module berekend.
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.
