Feature attributes (Heat Overlay)
This article is a stub.
Construction attributes
Each construction may also have attributes which can contribute to the calculations the Heat Overlay. These attributes are stored and used on a grid cell level.
These attributes can be changed individually per construction or per construction's function. In most cases, these attributes already exist as a function value.
| Icon | Attribute | Unit | Function value | Description |
|---|---|---|---|---|
| BOWEN_RATIO | ratio | Bowen ratio | Describes the rate of heat transfer for a surface that has moisture as a factor. | |
| FOLIAGE_CROWN_FACTOR | ratio | Foliage crown factor | The ratio between the height of tree trunks and the radius of the foliage of the tree. | |
| GREEN_M2 | m²/m² | Green space | The amount of the surface which is considered vegetation. |
Terrain attributes
| Attribute | Unit | Terrain type | Description |
