 See also [[Load Map]] for loading maps whose cells do not represent categories.
+If the "Null Value" parameter is specified, any cell corresponding to the original null value of the map, if provided, is converted to the new null value. This ensures that values originally represented by null value still representing null values, even if the null value definition changes. Any non-null value corresponding to the newly defined null value is also promoted to new null value.
 For a list of file formats that Load Categorical Map can load, the supported [[wp>Map_projection|projections]] and [[wp>Datum_(geodesy)|datums]], check the [[supported map formats#map_formats_supported_for_reading|supported map formats]].
