hydromt_fiat.components.ExposureGeomsComponent#

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

Custom exposure geometries component.

Parameters:

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

  • filename (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.

  • region_filename (str, optional) – The path to use for writing the region data to a file. By default “region.geojson”.

Attributes
