Spatial domain¶
Spatial domain represents 2D or 3D area defintion in the dataset. Spatial domain definition is not updateable.
Supported 2D formats¶
Grid (raster) data¶
- Regular rectangular grid
- Not equidistant spatial axis
Mesh data¶
Mesh elements can be triangles or quadrilaterals
3D layered data (Vertical domain)¶
Verticality is supported using layers. It is not true 3D element geometry. Vertical layers are supported for all supported 2D formats.
Static vertical layers¶
The vertical layer is not changing over time and is defined by vertical transformation
Supported formats: - Equidistant layers - Not equidistant layers
Variable vertical layers¶
The layer positions are defined for each timestep as in combined sigma-z.
Each layer is stored separately See storage docs
Temporal domain¶
Both equidistant and non-equidistant temporal defintion are supported
Items (variables)¶
Items (variables) definition:
- Name
- Type - value datatype (float, double,...)
- Quantity - defined by DHI.EUM ItemId (e.g. eumIWaterDepth) and UnitId (e.g. eumUmeter)
- NoDataValue - undefined, missing, or not available data value
