Clip Vector Data with GeoPandas

Learn how to clip geometries to the boundary of a polygon geometry using GeoPandas.

The example below shows you how to clip a set of vector geometries to the spatial extent / shape of another vector object. Both sets of geometries must be opened with GeoPandas as GeoDataFrames and be in the same Coordinate Reference System (CRS) for the clip() function in GeoPandas to work.

This example uses GeoPandas example data 'naturalearth_cities' and 'naturalearth_lowres', alongside a custom rectangle geometry made with shapely and then turned into a GeoDataFrame.


The object to be clipped will be clipped to the full extent of the clip object. If there are multiple polygons in clip object, the input data will be clipped to the total boundary of all polygons in clip object.

Import Packages

To begin, import the needed packages.

import matplotlib.pyplot as plt
import geopandas
from shapely.geometry import Polygon

Get or Create Example Data

Below, the example GeoPandas data is imported and opened as a GeoDataFrame. Additionally, a polygon is created with shapely and then converted into a GeoDataFrame with the same CRS as the GeoPandas world dataset.

capitals = geopandas.read_file(geopandas.datasets.get_path("naturalearth_cities"))
world = geopandas.read_file(geopandas.datasets.get_path("naturalearth_lowres"))

# Create a subset of the world data that is just the South American continent
south_america = world[world["continent"] == "South America"]

# Create a custom polygon
polygon = Polygon([(0, 0), (0, 90), (180, 90), (180, 0), (0, 0)])
poly_gdf = geopandas.GeoDataFrame([1], geometry=[polygon],

Plot the Unclipped Data

fig, (ax1, ax2) = plt.subplots(2, 1, figsize=(12, 8))
poly_gdf.boundary.plot(ax=ax1, color="red")
south_america.boundary.plot(ax=ax2, color="green")
capitals.plot(ax=ax2, color="purple")
ax1.set_title("All Unclipped World Data", fontsize=20)
ax2.set_title("All Unclipped Capital Data", fontsize=20)

Clip the Data

When you call clip(), the first object called is the object that will be clipped. The second object called is the clip extent. The returned output will be a new clipped GeoDataframe. All of the attributes for each returned geometry will be retained when you clip.


Recall that the data must be in the same CRS in order to use the clip() function. If the data are not in the same CRS, be sure to use the GeoPandas to_crs() method to ensure both datasets are in the same CRS.

Clip the World Data

world_clipped = geopandas.clip(world, polygon)

# Plot the clipped data
# The plot below shows the results of the clip function applied to the world
# sphinx_gallery_thumbnail_number = 2
fig, ax = plt.subplots(figsize=(12, 8))
world_clipped.plot(ax=ax, color="purple")
poly_gdf.boundary.plot(ax=ax, color="red")
ax.set_title("World Clipped", fontsize=20)

Clip the Capitals Data

capitals_clipped = geopandas.clip(capitals, south_america)

# Plot the clipped data
# The plot below shows the results of the clip function applied to the capital cities
fig, ax = plt.subplots(figsize=(12, 8))
capitals_clipped.plot(ax=ax, color="purple")
south_america.boundary.plot(ax=ax, color="green")
ax.set_title("Capitals Clipped", fontsize=20)
