geopandas.GeoSeries.area

property GeoSeries.area

Returns a Series containing the area of each geometry in the GeoSeries expressed in the units of the CRS.

GeoSeries.length

measure length

Notes

Area may be invalid for a geographic CRS using degrees as units; use GeoSeries.to_crs() to project geometries to a planar CRS before using this function.

Every operation in GeoPandas is planar, i.e. the potential third dimension is not taken into account.

Examples

>>> from shapely.geometry import Polygon, LineString, Point
>>> s = geopandas.GeoSeries(
...     [
...         Polygon([(0, 0), (1, 1), (0, 1)]),
...         Polygon([(10, 0), (10, 5), (0, 0)]),
...         Polygon([(0, 0), (2, 2), (2, 0)]),
...         LineString([(0, 0), (1, 1), (0, 1)]),
...         Point(0, 1)
...     ]
... )
>>> s
