geopandas.GeoSeries.get_precision#

GeoSeries.get_precision()[source]#

Returns a Series of the precision of each geometry.

If a precision has not been previously set, it will be 0, indicating regular double precision coordinates are in use. Otherwise, it will return the precision grid size that was set on a geometry.

Returns NaN for not-a-geometry values.

>>> from shapely.geometry import Point
>>> s = geopandas.GeoSeries(
...     [
...         Point(0, 1),
...         Point(0, 1, 2),
...         Point(0, 1.5, 2),
...     ]
... )
>>> s
0          POINT (0 1)
1      POINT Z (0 1 2)
2    POINT Z (0 1.5 2)

>>> s.get_precision()
0    0.0

2    0.0

>>> s1 = s.set_precision(1)
>>> s1
