Tree

Trees are used and represented in the Tygron Platform the in the following ways:

• Trees are generally represented by Buildings, with a Tree Function.
• The MultiPolygon stored in a Section of an individual Tree is the tree trunk, not the tree foliage.
• The MultiPolygon stored in a Section of a part of a forest is the region where potentially tree trunks are located.
• The height of trees is calculated using the difference between the DTM and the DSM during the New Project Wizard phase.
• The height of trees is stored in the FLOOR_HEIGHT_M attribute, in amounts of meters.

Functions

The following functions for trees and forests exist:

Name	ID	Category	Description
Birch	953	NATURE
Default deciduous trees	440	NATURE
Default pine trees	888	NATURE
Italian Poplar	954	NATURE
Larch	951	NATURE
Mangrove forest	753	NATURE	Coastal ecosystem characterized by salt-tolerant mangrove trees providing shoreline protection and biodiversity habitats
Oak	950	NATURE	Oak trees (genus: Quercus) are deciduous trees. The European oak is a common oak tree species
Palm trees	937	NATURE	Palm trees increase the amount of greenery
Willow	952	NATURE	The willow (genus: Salix) is a deciduous tree. A common willow tree is the white willow
Wooded bank	963	NATURE	A linear planting of trees and shrubs serving as a natural boundary or windbreak

Overlays

Tree (building)s and their properties are used in various overlays:

• Heat Stress Overlay
  • Foliage crown factor (Heat Stress Overlay)
  • Max trunk distance (Heat Stress Overlay)
  • Wind decline angle (Heat Stress Overlay)
  • FAQ Foliage Heat Stress Overlay
  • Foliage result type (Heat Stress Overlay)
  • Foliage height calculation model (Heat Stress Overlay)

• Shadow Overlay
  • Foliage crown factor (Shadow Overlay)
  • Foliage result type (Shadow Overlay)
• Traffic Overlay
  • Min tree height m (Traffic Overlay)
  • Min tree height m (Traffic NO2 Overlay)
  • Trees result type (Traffic NO2 Overlay)

• Water Overlay
  • Evapotranspiration model (Water Overlay)
  • Ground transpiration formula (Water Overlay)

Foliage

The Heat Stress Overlay (and Shadow Overlay) use Foliage of trees as input, either as:

• Buildings with TreeFunctions, calculating the foliage using the [[Foliage crown factor (Heat Stress Overlay)
• Foliage areas (Heat Stress Overlay)
• Foliage height prequel (Heat Stress Overlay)

Foliage can be detected using an Inference Overlay using the Foliage (Neural Network).

Notes

• The FLOOR_HEIGHT_M also affects how tall the tree is in the 3D Visualization.
• Roots of trees can be seen in the Underground visualization
