Shapely intersection over union

WebbSpatial intersections ¶ So far we saw how to join features based on their location, below we see how to intersect two layers and create new geometries. Spatial joins preserve geometry and only get attributes. However, intersections and unions will create new (often smaller) geometries that include the characteristics of both the layers.
