Function shared_paths

shapely/ops.py:320–341

Find paths shared between the two given lineal geometries. Returns a GeometryCollection with two elements: - First element is a MultiLineString containing shared paths with the same direction for both inputs. - Second element is a MultiLineString containing shared paths with th

(g1, g2)
