  Example of a foliage areas file. In this example dataset, each tree crown is round, which is not realistic, but can be used for the Heat module.

  The imported areas in the Platform. Since the tree crowns are round (which is not that realistic), the tree crowns overlap with buildings.

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 only contain tree locations as points, you should instead import them as buildings in the geo data wizard. The imported trees will then use their height and their function's (or if supplied: building's) CROWN FACTOR 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.
• The already present tree constructions are ignored when choosing to import foliage height areas
