Knowing where and at what height the foliage is present geographically is an important factor in Shade and Skyview calculations. Unfortunately, foliage is not always stored as geographical data in Landuse Geo-services. Instead, sometimes only the tree trunks have been recorded. Additionally, when designing new scenario's, foliage for newly added trees cannot be obtained from existing services and must instead be generated by some algorithm. In order to facilitate generating foliage, the foliage crown factor function value has been added.
Foliage Crown Factor
The foliage crown factor is a means to determine what areas surrounding tree trunks get covered by the trees' foliage. By multiplying the tree's height with the foliage crown factor one obtains the foliage radius.
