Notes

• The areas that need to be imported are areas of the foliage crown along with an attribute containing the height of the foliage, relative to the terrain height.
• If you have a file that contains tree locations as points, you can instead import them as Buildings in the geo data wizard. The imported trees will then use, if supplied, the height and foliage crown factor of the selected tree functions to determine the foliage area.
• When you have chosen to import foliage height areas, there is also an option to do nothing. Then no foliage height is used. The third option: Select existing is only for if you already have imported these areas in the Platform.
• The already present tree Buildings are ignored when choosing to import foliage height areas.
