**Intersection** of two **polygons**. For this exercise, we are going to use 2 individual **polygons**: the district of Muette extracted from the districts dataset, and the green urban **area** of Boulogne, a large public park in the west of Paris, extracted from the land_use dataset. The two **polygons** have already been assigned to the muette and park_boulogne.
