gemgis.vector.create_unified_buffer#

gemgis.vector.create_unified_buffer(geom_object: Union[geopandas.geodataframe.GeoDataFrame, List[shapely.geometry.base.BaseGeometry]], distance: Union[numpy.ndarray, List[Union[int, float]], float, int]) → shapely.geometry.multipolygon.MultiPolygon#

Creating a unified buffer around Shapely LineStrings or Points

Parameters

  • geom_object (Union[gpd.geodataframe.GeoDataFrame, List[shapely.geometry.base.BaseGeometry]]) – GeoDataFrame or List of Shapely objects

  • distance (Union[np.ndarray, List[Union[float, int]], Union[float, int]]) – Distance of the buffer around the geometry object, e.g. distance=10

Returns

polygon – Polygon representing the buffered area around a geometry object

Return type

shapely.geometry.multipolygon.MultiPolygon

New in version 1.0.x.

Example

>>> # Loading Libraries and creating Point
>>> import gemgis as gg
>>> from shapely.geometry import Point
>>> point1 = Point(0,0)
>>> point1.wkt
'POINT (0 0)'

>>> # Creating Point
>>> point2 = Point(20,20)
>>> point2.wkt
'POINT (20 20)'

>>> # Creating list of points
>>> point_list = [point1, point2]

>>> # Creating unified buffer
>>> unified_buffer = gg.vector.create_unified_buffer(geom_object=point_list, distance=10)
>>> unified_buffer
'MULTIPOLYGON (((10 0, 9.95184726672197 -0.980171403295605, 9.807852804032306 -1.950903220161281, 9.56940335732209
