New composite areas that are divided per aggregation areas dont have individual values for Ground Floor Height And Ground Floor Elevation

hydomt_fiat version checks

• I have checked that this issue has not already been reported.
• I have checked that this bug exists on the latest version of hydomt_fiat.

Reproducible Example

When using new composite areas that need to be divided to fall in different aggregation areas, the resulting splitted polygons have the values for ground elevation and ground floor height of the original polygons extents.

Current behaviour

When using new composite areas that need to be divided to fall in different aggregation areas, the resulting splitted polygons have the values for ground elevation and ground floor height of the original polygons extents and not the splitted ones:

The split part takes place here:

hydromt_fiat/hydromt_fiat/workflows/exposure_vector.py

Lines 1453 to 1459 in 7ca85e8

	new_objects, aggregated_objects_geoms, _ = join_exposure_aggregation_areas(
	_new_exposure_geoms.merge(new_objects, on="Object ID"),
	aggregation_area_fn=aggregation_area_fn,
	attribute_names=attribute_names,
	label_names=label_names,
	new_composite_area=True,
	)

Desired behaviour

The splitted polygons should have their individual ground elevation and ground floor height be calculated. This means that this part should be moved earlier in the code:

hydromt_fiat/hydromt_fiat/workflows/exposure_vector.py

Lines 1453 to 1459 in 7ca85e8

	new_objects, aggregated_objects_geoms, _ = join_exposure_aggregation_areas(
	_new_exposure_geoms.merge(new_objects, on="Object ID"),
	aggregation_area_fn=aggregation_area_fn,
	attribute_names=attribute_names,
	label_names=label_names,
	new_composite_area=True,
	)

Task list

• Update code
• Test use
