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.
