Transformer.point_as_polygon

classmethod Transformer.point_as_polygon(multi_poly_coords)

Make the coordinates of a single ‘Point’ (in a ‘MultiPolygon’) be reformatted to a ‘Polygon’-like coordinates.

The list of coordinates of some ‘MultiPolygon’ features may contain single points. In order to reformat such multipart geometry (from dict into shapely.geometry type), there is a need to ensure each of the constituent parts is a shapely.geometry.Polygon.

Parameters:

multi_poly_coords (list) – original data of coordinates of a shapely.geometry.MultiPolygon feature

Returns:

coordinates that are reformatted as appropriate

Return type:

list

Examples:

>>> from pydriosm.reader import Transformer

>>> geometry = {
...     'type': 'MultiPolygon',
...     'coordinates': [[[[-0.6920145, 52.6753268], [-0.6920145, 52.6753268]]]]
... }
>>> mp_coords = geometry['coordinates']

>>> mp_coords_ = Transformer.point_as_polygon(mp_coords)
>>> mp_coords_
[[[[-0.6920145, 52.6753268],
   [-0.6920145, 52.6753268],
   [-0.6920145, 52.6753268]]]]
