GeoDataFrame.delaunay_triangles

Return Delaunay triangulation of the vertices of each geometry.

Unlike geopandas, which collects all vertices across the entire GeoSeries and computes a single triangulation, Sedona computes the triangulation per row. Each input geometry produces one GeometryCollection containing its triangles. The output GeoSeries has the same length as the input.

Signature

delaunay_triangles(tolerance=0.0, only_edges=False)

Parameters

float

default:"0.0"

Snapping tolerance for vertices to be considered equal.

bool

default:"False"

If True, return only the edges of the triangulation as a MultiLineString. If False, return triangles as a GeometryCollection of Polygons.

Returns

GeoSeries

Examples

>>> from sedona.spark.geopandas import GeoSeries
>>> from shapely.geometry import MultiPoint
>>> s = GeoSeries([MultiPoint([(0, 0), (1, 0), (0.5, 1)])])
>>> s.delaunay_triangles()
