Shade calculation model (Heat Overlay)
Shades are an important factor in the Heat Overlay. Whether a cell is shaded or not determines which PET function is used, PETsun or PETshade, night. In the model described by the DPRA Heat stress report, cells can be shaded by buildings, terrain and foliage.
The Shade calculation model is currently used by two Grid Overlays; the Heat Overlay and the Shadow Overlay.
