I have two polygon layers. One containing vegetation features and one containing the borders of different monitoring areas. I want to calculate the total size of different vegetation types per monitoring area, however, the vegetation features often go over the borders of two areas (see example below, with red monitoring area border).
I want to split the vegetation features that cross borders so that they fit to the borders of the monitoring areas. How can that be done? I found the split line by line tool in QGIS but couldn´t find the same for polygon. Splitting manually is not an option as I have many thousand features.
