geopandas.GeoSeries.simplify

GeoSeries.simplify(*args, **kwargs)

Returns a GeoSeries containing a simplified representation of each geometry.

See http://shapely.readthedocs.io/en/latest/manual.html#object.simplify for details

Parameters

tolerancefloat

All points in a simplified geometry will be no more than tolerance distance from the original.

preserve_topology: bool (default True)

False uses a quicker algorithm, but may produce self-intersecting or otherwise invalid geometries.

Notes

Invalid geometric objects may result from simplification that does not preserve topology and simplification may be sensitive to the order of coordinates: two geometries differing only in order of coordinates may be simplified differently.

Examples

>>> from shapely.geometry import Point, LineString
>>> s = geopandas.GeoSeries(
...     [Point(0, 0).buffer(1), LineString([(0, 0), (1, 10), (0, 20)])]
... )
>>> s

1    LINESTRING (0.00000 0.00000, 1.00000 10.00000,...
dtype: geometry

>>> s.simplify(1)
