Notes

• This water limitation area is not to be confused with the Limit Map functionality that applies to all Overlays in the project and is always shaped in a rectangle.
• It is also possible to add a different attribute name for the limitation area, but with a value above 0. In that case, in the extra step in the wizard, choose for the option Select existing limitation areas based on attribute and select the custom attribute name of your limitation area.v
