trajectory_supervisor.helper_funcs.src.shapely_conversions.extract_polygon_outline(shapely_geometry: <module 'shapely.geometry' from '/home/docs/checkouts/readthedocs.org/user_builds/trajectorysupervisor/envs/latest/lib/python3.7/site-packages/shapely/geometry/__init__.py'>) → numpy.ndarray[source]

Extract the key outline coordinates of a shapely shape (including multi-shapes like MultiPolygon). The following types ares supported:

  • Polygon: The outline of the polygon is returned

  • MultiPolygon: The outline of the largest polygon is returned

  • GeometryCollection: The largest polygon in the set is returned, if no polygon is present ‘None’ is returned

  • LineString: ‘None’ is returned, since the shape is a line and does not host volume information

For any other type, an error is raised.

Parameters

shapely_geometry – shapely-geometry of interest

Returns

  • polygon_outline - outline coordinates in form of a numpy array with columns x, y
