+    The factory will take care of filling in the process parameters
+    based on matching column names in dataframe from the job database,
+    with some additional override/fallback options:
+
+    -   When provided, ``parameter_column_map`` will be consulted

+    -   One common case is handled automatically as convenience functionality.

+        When:
+
+        - ``parameter_column_map`` is not provided (or set to ``None``),

+        - and the dataframe is a GeoPandas dataframe with a *single geometry* column,
+
+        then this parameter and this geometries column will be linked automatically.
+
+    -   If a parameter can not be matched with a column by name as described above,
+        a default value will be picked,
+        first by looking in ``parameter_defaults`` (if provided),
+        and then by looking up the default value from the parameter schema in the process definition.
+    -   Finally if no (default) value can be determined and the parameter
+        is not flagged as optional, an error will be raised.
