Clip (Data Management)

Summary

Creates a spatial subset of a raster dataset.

Illustration

Usage

• This tool allows you to extract a portion of a raster dataset based on a template extent. The clip output includes any pixels that intersect the template extent.

• The clipped area is specified either by a rectangular envelope using minimum and maximum x- and y-coordinates or by using an output extent file. If the clip extent specified is not aligned with the input raster dataset, this 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.

• An existing raster or vector layer can be used as the clip extent. If you are using a feature class as the output extent, you have the option to clip the raster by the minimum bounding rectangle of the feature class or by the polygon geometry of the features. 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.

• When using ArcMap, you also have the ability to use the selected features as the clipping extent. If a feature within the feature class is selected and Use input features for clipping geometry is checked, then the output clips out the areas that are selected. If a feature within the feature class is selected but Use input features for clipping geometry is not checked, then the output clips out the minimum bounding rectangle for that feature.

• You can save your output to BIL, BIP, BMP, BSQ, DAT, GIF, GRID, IMG, JPEG, JPEG 2000, PNG, TIFF, or any geodatabase raster dataset.

• If the clip extent specified is not aligned with the input raster dataset, this 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.

• 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.

• The extent values must be in the same spatial coordinates and units as the raster dataset.

Syntax

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

Parameter	Explanation	Data 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. NONE —The raster dataset is clipped based on the minimum bounding rectangle of the feature class. ClippingGeometry —The 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.	Boolean
