==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.


==Overlays==
The selectable modules are:
Several overlays with data that influence heat are available :
* [[Heat_DPRA_Module|DPRA Heat stress module]]. This module is more detailed and based on the new [[DPRA guideline|Dutch DPRA standards]]. It can generate multiple Heat Overlay [[Result type (Heat Overlay)|result types]] as child overlays;
* The PET map (real feel temperature, wind chill). In accordance to the DPRA guideline: https://ruimtelijkeadaptatie.nl/stresstest/bijsluiter/hitte/pet-hittekaart/
* 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.
* Foliage (map with tree heights)
* Shade
* Average Sky View
*      Sky view (percentage sky view in relation to total view),
* UHI (Urban heat island effect)
*      Temperature of atmosphere
* Vegetation average
* Vegetation (yes/no))
* Bowen ratio (evaporation ratio)
* Wind speed


De  overlays are calculated by our cuda module

De wizard is ook te openen. Deze heeft in stap 1 een datum tabel.
* The Heat Stress overlay present in the [[Climategame]] uses the UNESCO Heat stress model.
* Per datum geeft je uren van de dag aan.
* Per uur van de dag geef je weer en zon waardes aan.
* De zonne hoeken (altitude en azimuth) kunnen automatisch worden berekend op basis van de project locatie en de tijd zone. De tijdzone halen wij ook op, op basis van de project locatie.
 
Stap 2 gaat over boomhoogtes. Bomen zijn vaak alleen ingetekend als stam, maar de kroon van de boom is juist belangrijkt. Daarom bieden wij 3 varianten aan:
* Op basis van BGT gebouwen die bomen representeren.
Boom hoogte * boom kroon factor bepaald of de omringende cellen ook schaduw krijgen van de bladeren van de boom.
* Area geometriën aangeleverd als geojson of  WFS service, waarin de boomhoogte per area staat
* Geotiff, waar per cell de boomhoogte staat.

Heat is calculated in accordance to the Dutch standard for heat stress:

Example of the DPRA heat stress overlay

We are working on a new Heat Stress Overlay module, which will be in accordance with the new Dutch DPRA standards. This module is still under construction, as is the documentation, however a Beta version of the module is available on the Preview server for our partners.

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:

Notes

  • The Heat Stress overlay present in the Climategame uses the UNESCO Heat stress model.
