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


We are working on a new heat module in accordance to 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 Stress Overlay Wizard]].


==Overlays==
The selectable modules are:
Several overlays with data that influence heat are available :
* [[DPRA Heat Stress Module]]. This module is more detailed and based on the 2019 {{Heat DPRA Report}}. It can generate multiple Heat Stress Overlay [[Result types (Heat Stress Overlay)|result types]] as child overlays;
* 1. The PET map (real feel temperature, wind chill). In accordance to the DPRA guideline: https://ruimtelijkeadaptatie.nl/stresstest/bijsluiter/hitte/pet-hittekaart/
* [[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.
* 2. Foliage (map with tree heights)
* 3. Shade
* 4. Average Sky View
* 5. Sky view (percentage sky view in relation to total view),
* 6. UHI (Urban heat island effect)
* 7. Temperature of atmosphere
* 8. Vegetation average
* 9. Vegetation (yes/no))
* 10. Bowen ratio (evaporation ratio)
* 11. Wind speed


De  overlays are calculated by our cuda module

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:
1. 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.
2. Area geometriën aangeleverd als geojson of  WFS service, waarin de boomhoogte per area staat
3. Geotiff, waar per cell de boomhoogte staat.
