Creates a raster object that is clipped according to the extent of an input raster dataset or the shape of an input polygon feature class.


Use the Clip function to extract a portion of your raster dataset according to a defined spatial extent. For example, to process a small region within a Landsat image, you can clip the raster to the region of interest.

The function creates a raster object that has been cut out from the referenced raster object.

The referenced raster dataset for the raster object is temporary. To make it permanent, you can call the raster object's save method.


Clip (in_raster, aoi)
パラメーター説明データ タイプ

The input raster.


Defines the area of interest (AOI), or clipping extent, used to clip the raster. Supported AOI options include Raster, Extent, and Polygon geometry.

データ タイプ説明

The output clipped raster.


Clip example 1

Clips a national land cover raster dataset to the extent of a single state.

import arcpy
from arcpy.ia import *

# Set input raster
in_raster = arcpy.Raster("USA_Landcover.tif")

# Clip the raster using a feature extent
clip_raster = arcpy.ia.Clip(in_raster, aoi = "C:\Data\California_State.shp")"California_Landcover.tif")
Clip example 2

Clips a raster object using a Polygon class.

import arcpy
from arcpy.ia import *

# Set input raster
in_raster = arcpy.Raster("us_landcover.tif")

# Create a polygon geometry object using the array object
coordinates = [[-102.78838, 42.9953], [-104.0594, 43.8529], 
	[-104.0489, 45.942993], [-102.78838, 42.9953]]
array = arcpy.Array([arcpy.Point(x, y) for x, y in coordinates])
polygon_geometry=arcpy.Polygon(array, arcpy.SpatialReference(4326))

# Clip the raster using the polygon geometry
clip_raster = arcpy.ia.Clip(in_raster, aoi = polygon_geometry)"landcover_clipped_by_polygon_geometry.tif")
