geopandas.GeoSeries.segmentize#

GeoSeries.segmentize(max_segment_length)[source]#

Returns a GeoSeries with vertices added to line segments based on maximum segment length.

Additional vertices will be added to every line segment in an input geometry so that segments are no longer than the provided maximum segment length. New vertices will evenly subdivide each segment. Only linear components of input geometries are densified; other geometries are returned unmodified.

Parameters:

max_segment_lengthfloat | array-like: Additional vertices will be added so that all line segments are no longer than this value. Must be greater than 0.

Returns:

GeoSeries
