Heat Stress Overlay
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.
Overlays
Several overlays with data that influence heat are available :
- The PET map (real feel temperature, wind chill). In accordance to the DPRA guideline: https://ruimtelijkeadaptatie.nl/stresstest/bijsluiter/hitte/pet-hittekaart/
- 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): 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.
Calculations
Heat is calculated in accordance to the Dutch standard for heat stress: https://ruimtelijkeadaptatie.nl/stresstest/bijsluiter/hitte/ For more detailed implementation we used RIVM-documentation: https://www.rivm.nl/bibliotheek/rapporten/2019-0008.pdf
Results
With a Heat Overlay, one can generate different kinds of results. For further information about these outcomes, see result types.
