hydromt_fiat.components.ExposureGeomsComponent#

class hydromt_fiat.components.ExposureGeomsComponent(model: Model, *, filename: Path | str = 'exposure/{name}.fgb', region_component: str | None = None)[source]#

Exposure geometries component.

Parameters:

  • model (Model) – HydroMT model instance (FIATModel).

  • filename (Path | str, optional) – The path to use for reading and writing of component data by default. By default “exposure/{name}.fgb”.

  • region_component (str, optional) – The name of the region component to use as reference for this component’s region. If None, the region will be set to the union of all geometries in the data dictionary. By default None.

Attributes

bounds

Return the total bounds of the model region.

crs

Provide access to the CRS of the model region.

data

Geometries.

data_catalog

Return the data catalog of the model this component is associated with.

model

Return the model object this component is associated with.

name_in_model

Find the name of the component in the parent model components.

region

Provide access to the underlying GeoDataFrame data of the model region.

root

Return the root of the model this component is associated with.
