pyguymer3.geo.extract_polys(shape, /, *, onlyValid=False, repair=False)[source]

Extract the Polygons from the shape

This function accepts any Shapely geometry and returns a flat list of all of the Polygons contained within.

Parameters:

  • shape (list, shapely.geometry.point.Point, shapely.geometry.multipoint.MultiPoint, shapely.geometry.polygon.LinearRing, shapely.geometry.linestring.LineString, shapely.geometry.multilinestring.MultiLineString, shapely.geometry.polygon.Polygon, shapely.geometry.multipolygon.MultiPolygon, shapely.geometry.collection.GeometryCollection) – the Shapely geometry

  • onlyValid (bool, optional) – only return valid Polygons (checks for validity can take a while, if being called often)

  • repair (bool, optional) – attempt to repair invalid Polygons

Returns:

polys – a flat list of all of the Polygons

Return type:

list of shapely.geometry.polygon.Polygon

Note

To pass GeoJSON objects you must first convert them to Shapely objects by doing something like shape = shapely.geometry.shape(shape).
