gemgis.vector.explode_polygon

gemgis.vector.explode_polygon(polygon: shapely.geometry.polygon.Polygon) → List[shapely.geometry.point.Point]

Exploding Shapely Polygon to list of Points

Parameters

polygon (shapely.geometry.polygon.Polygon) – Shapely Polygon from which vertices are extracted, e.g. polygon = Polygon([(0, 0), (1, 1), (1, 0)])

Returns

point_list – List containing the vertices of a polygon as Shapely Points

Return type

List[shapely.geometry.point.Point]

New in version 1.0.x.

Example

>>> # Loading Libraries and creating Polygon
>>> import gemgis as gg
>>> from shapely.geometry import Polygon
>>> polygon = Polygon([(0, 0), (1, 1), (1, 0)])
>>> polygon.wkt
'POLYGON ((0 0, 1 1, 1 0, 0 0))'

>>> # Exploding Polygon into single Points
>>> polygon_exploded = gg.vector.explode_polygon(polygon=polygon)
>>> polygon_exploded
[<shapely.geometry.point.Point at 0x201459734f0>,
<shapely.geometry.point.Point at 0x20145973670>,
<shapely.geometry.point.Point at 0x20145973640>,
<shapely.geometry.point.Point at 0x201459732e0>]

>>> # Inspecting the first element of the list
>>> polygon_exploded[0].wkt
'POINT (0 0)'

>>> # Inspecting the second element of the list
>>> polygon_exploded[1].wkt
'POINT (1 1)'
