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.  


==Surface==
===Terrain elevation===
In the Tygron Engine there are different land types available. Each land type has different predefined attributes that affect [[indicators]] and [[Overlay|overlays]] such as [[Green (Indicator)|green]], [[Livability (Indicator)|livability]] and the [[Rainfall_(Overlay)|rainfall flooding]]. All types are described in the table below.
{{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.

Terrains in relation to Terrain Types and Height sectors.

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.
