Summary

Creates a spatial subset of a raster dataset.

Usage

Syntax

Clip_management (in_raster, rectangle, out_raster, {in_template_dataset}, {nodata_value}, {clipping_geometry})
ParameterExplanationData Type
in_raster

The input raster dataset.

Raster layer
rectangle

The four coordinates defining the minimum bounding rectangle to be clipped. Define in this order: X-Minimum, Y-Minimum, X-Maximum, Y-Maximum.

If the clip extent specified is not aligned with the input raster dataset, the Clip tool makes sure that the proper alignment is used. This may cause the output to have a slightly different extent than specified in the tool.

Envelope
out_raster

The output raster dataset. Make sure that this output format is able to support the proper pixel depth.

When storing the raster dataset in a file format, you need to specify the file extension:

  • .bil—ESRI BIL
  • .bip—ESRI BIP
  • .bmp—BMP
  • .bsq—ESRI BSQ
  • .dat—ENVI DAT
  • .gif—GIF
  • .img—ERDAS IMAGINE file
  • .jpg—JPEG
  • .jp2—JPEG 2000
  • .png—PNG
  • .tif—TIFF
  • no extension—ESRI GRID

When storing a raster dataset in a geodatabase, no file extension should be added to the name of the raster dataset.

When storing your raster dataset to a JPEG file, a JPEG 2000 file, a TIFF file, or a geodatabase, you can specify a compression type and compression quality.

Raster dataset
in_template_dataset
(Optional)

An existing raster or vector layer, which can be used as the clip extent. The clip output includes any pixels that intersect the minimum bounding rectangle.

If a feature class is used as the output extent and you want to clip the raster based on the polygon features, choose the ClippingGeometry option. If Clipping Geometry is used, then the pixel depth of the output may be promoted. Therefore, you need to make sure that the output format can support the proper pixel depth.

Raster Layer; Feature Layer
nodata_value
(Optional)

All the pixels with the specified value will be set to NoData in the output raster dataset.

Double
clipping_geometry
(Optional)

If you are using a feature class as the output extent, you have the option to clip the raster by the extent of the feature class or by its polygon perimeter.

  • NONEThe raster dataset is clipped based on the minimum bounding rectangle of the feature class.
  • ClippingGeometryThe raster dataset is clipped based on the perimeter of the polygon shape.

If clipping geometry is used, then the pixel depth of the output may be promoted. Therefore, you need to make sure that the output format can support the proper pixel depth.

Code Sample

Clip example 1 (Python window)

This is a Python sample for the Clip tool.

import arcpy
arcpy.Clip_management("c:/data/image.tif","1952602 294196 1953546 296176",
                      "c:/data/clip.gdb/clip01", "#", "#", "NONE")
Clip example 2 (stand-alone script)

This is a Python script sample for the Clip tool.

##Usage: Clip_management in_raster rectangle out_raster {in_template_dataset} {nodata_value} {NONE | ClippingGeometry}

try:
    import arcpy
    arcpy.env.workspace = r"C:/Workspace"
    
    ##Clip Raster Dataset by known extent - Left Bottom Right Top
    arcpy.Clip_management("image.tif","1952602.23 294196.279 1953546.23 296176.279","clip.gdb/clip", "#", "#", "NONE")
    
    ##Clip Raster Dataset with feature geometry
    arcpy.Clip_management("image.tif", "#", "clip.tif","feature.shp", "0", "ClippingGeometry")
except:
    print "Clip example failed."
    print arcpy.GetMessages()
