The composition of the surface (above-ground) and sub-surface (underground) in the [[Project]] is defined using Terrains. A Terrain has a polygons indicating its boundaries and a [[Terrain Type]] indicating its type. For every location in the project, two terrains will be present: one [[layer|surface layer]] Terrain and one [[layer|underground]] Terrain.


==What is terrain?==
===Terrain Type===
Terrain in the tygron engine, describes the surface and sub-surface (underground) and elevation of your project. Terrain excludes everything which is build-up on the terrain, which is described in buildings. Terrain can be editted via GEO DATA -> Terrain.
{{main|Terrain Type}}
The Terrain polygons each have an associated [[Terrain Type]], which holds the actual data of what the Terrain polygon represents. Only the [[Terrain Type]] holds any [[Attribute]]s to define the Terrain's behavior.  


==How does land type relate to the Tygron Engine?==
===Terrain elevation===
: Land type in the Tygron Engine describes what types of surface a given area is, for example grassland, concrete, or water. Different land types have different effects. If the area is designated as grass land, it has a small positive effect on the [[Livability (Indicator)|livability]] and [[Heat (Indicator)|heat stress]] indicators. These indicators will be negatively affected if the land type is set as concrete. Open water drastically improves the available water storage.
{{main|Elevation model}}
Although conceptually related, the [[elevation model|height of the Terrain]] is explicitly not part of the Terrain itself or of the [[Terrain Type]]s. Instead, based on the presence or selection of specific [[Terrain Type]]s, modifications to the [[elevation model]] are made. For example, replacing a terrain with a type of [[water (Terrain Attribute)|water]] will cause a change for the [[elevation model]], but that change can be suppressed.


==Surface==
Terrains define what [[Terrain Type]] is present for any given location, and thus how the ground behaves. The [[elevation model]] defines the height of the ground for any given location.
: In the Tygron Engine there are different land types available. Each land type has different predefined attributes that affect [[indicators]] such as [[Green (Indicator)|green]] and [[Livability (Indicator)|livability]].
The following land types are available:

The composition of the surface (above-ground) and sub-surface (underground) in the Project is defined using Terrains. A Terrain has a polygons indicating its boundaries and a Terrain Type indicating its type. For every location in the project, two terrains will be present: one surface layer Terrain and one underground Terrain.

Terrain Type

Main article: Terrain Type

The Terrain polygons each have an associated Terrain Type, which holds the actual data of what the Terrain polygon represents. Only the Terrain Type holds any Attributes to define the Terrain's behavior.

Terrain elevation

Main article: Elevation model

Although conceptually related, the height of the Terrain is explicitly not part of the Terrain itself or of the Terrain Types. Instead, based on the presence or selection of specific Terrain Types, modifications to the elevation model are made. For example, replacing a terrain with a type of water will cause a change for the elevation model, but that change can be suppressed.

Terrains define what Terrain Type is present for any given location, and thus how the ground behaves. The elevation model defines the height of the ground for any given location.

Notes

  • When creating a new project in the Netherlands, the default Terrains and their Terrain Types are based on data from the BRO.
  • Terrains are never edited directly. Instead, users draw or import geometries for alternative Terrain Types.
