The foliage crown factor is used to calculate the extend of foliage, which can influence the calculation of the sky view and the shade. The height of the construction multiplied by the the crown factor yields the radius of the foliage.
The crown factor is used because the extend of foliage itself is not consistently available as geographical data in geo-services for land use. Instead, only the extent of tree trunks may be recorded.
Notes
- Foliage can be calculated based on the FOLIAGE_CROWN_FACTOR. This calculation can be superseded when the Heat Overlay is configured to use either Areas or a GeoTiff to determine foliage height. In those cases the FOLIAGE_CROWN_FACTOR of constructions is unused.
