gemgis.vector.intersection_polygon_polygon

gemgis.vector.intersection_polygon_polygon(polygon1: shapely.geometry.polygon.Polygon, polygon2: shapely.geometry.polygon.Polygon) → Union[shapely.geometry.linestring.LineString, shapely.geometry.polygon.Polygon]

Calculating the intersection between to Shapely Polygons

Parameters

• polygon1 (shapely.geometry.polygon.Polygon) – First polygon used for intersecting, e.g. polygon1=Polygon([[0, 0], [10, 0], [10, 10], [0, 10], [0, 0]])

• polygon2 (shapely.geometry.polygon.Polygon) – Second polygon used for intersecting, e.g. polygon2=Polygon([[0, 0], [10, 0], [10, 10], [0, 10], [0, 0]])

Returns

intersection – Intersected geometry as Shapely Object

Return type

Union[shapely.geometry.linestring.LineString, shapely.geometry.polygon.Polygon]

New in version 1.0.x.

Example

>>> # Loading Libraries
>>> import gemgis as gg
>>> from shapely.geometry import Polygon
>>> polygon1 = Polygon([[0, 0], [10, 0], [10, 10], [0, 10], [0, 0]])
>>> polygon1.wkt
'POLYGON ((0 0, 10 0, 10 10, 0 10, 0 0))'

>>> # Creating second Polygon
>>> polygon2 = Polygon([[10, 0], [20, 0], [20, 10], [10, 10], [10, 0]])
>>> polygon2.wkt
'POLYGON ((10 0, 20 0, 20 10, 10 10, 10 0))'

>>> # Calculating the intersection between two polygons
>>> intersection = gg.vector.intersection_polygon_polygon(polygon1=polygon1, polygon2=polygon2)
>>> intersection.wkt
'LINESTRING (10 0, 10 10)'
