Knowing where the foliage is present and at what height it is situated for each grid cell of a Heat Overlay is an important factor for the Shade and Skyview calculation models.
The Foliage Height for each grid cell can be determined in three ways:
- By supplying the areas which each hold the height of foliage for the whole polygon of a particular area.
- By supplying a geotiff which holds the foliage heights as a grid.
- By using the foliage functions and their height and foliage crown factor function value.
The mentioned options are currently exclusive; Only one option will determine the foliage height and they currently cannot be combined.
It depends on the available data and the use case which option you will choose as a user. When developing future scenario's in which other users can add foliage to unknown location, it is advised to use the Foliage crown factor option.
