 Hello, in a previous video we've used the inverted polygon shapeburst fill to highlight the study area. That's however not very useful for the legend, therefore we need to create a copy that is styled in a different way. So we duplicate the rule catchment polygon and we're now going to style this in the layer styling panel by simply removing the shapeburst fill, the simple line remains. This will later be used in the legend. So in this video you've learned how to create a duplicate of the rule catchment boundary for a simple line styling that can be used for the legend later.
