hydromt_fiat.workflows.exposure_setup(exposure_data: GeoDataFrame, exposure_type_column: str, *, exposure_linking: DataFrame | None = None, exposure_type_fill: str | None = None) → GeoDataFrame[source]#

Prep the raw exposure data for later fuctions/ methods.

Here the exposure type can be mapped for better linking later on.

Parameters:

  • exposure_data (gpd.GeoDataFrame) – The raw exposure data.

  • exposure_type_column (str) – The name of column that specifies the exposure type, e.g. occupancy type.

  • exposure_linking (pd.DataFrame, optional) – A custom mapping to table to first translate the exposure types in order to better link with the vulnerability data. A translation layer really. By default None

  • exposure_type_fill (str, optional) – Value to which missing entries in the exposure type column will be mapped to, if provided. By default None

Returns:

The resulting exposure data.

Return type:

gpd.GeoDataFrame
