geopandas.GeoSeries.remove_repeated_points#

GeoSeries.remove_repeated_points(tolerance=0.0)[source]#

Returns a GeoSeries containing a copy of the input geometry with repeated points removed.

From the start of the coordinate sequence, each next point within the tolerance is removed.

Removing repeated points with a non-zero tolerance may result in an invalid geometry being returned.

Parameters:

tolerancefloat, default 0.0: Remove all points within this distance of each other. Use 0.0 to remove only exactly repeated points (the default).

Examples

>>> from shapely import LineString, Polygon
>>> s = geopandas.GeoSeries(
...     [
...        LineString([(0, 0), (0, 0), (1, 0)]),
...        Polygon([(0, 0), (0, 0.5), (0, 1), (0.5, 1), (0,0)]),
...     ],
... )
>>> s
0                 LINESTRING (0 0, 0 0, 1 0)
1    POLYGON ((0 0, 0 0.5, 0 1, 0.5 1, 0 0))

>>> s.remove_repeated_points(tolerance=0.0)
