Rotate (Data Management)

Summary

Turns a raster dataset around a specified pivot point.

Illustration

Rotate illustration

Usage

  • By default, the rotation is around the center point of the raster. The rotation point can be changed using the optional Pivot Point parameter.

  • Resampling is only done if the angle is not a multiple of 90.

  • Specify a rotation angle between 0 and 360 to rotate the raster clockwise. To rotate the raster in the counterclockwise direction, specify the angle as a negative value.

  • You can save the output to BIL, BIP, BMP, BSQ, DAT, Esri Grid, GIF, IMG, JPEG, JPEG 2000, PNG, TIFF, MRF, or CRF format, or any geodatabase raster dataset.

  • When storing a raster dataset to a JPEG format file, a JPEG 2000 format file, or a geodatabase, you can specify a Compression Type value and a Compression Quality value in the geoprocessing environments.

  • This tool supports multidimensional raster data. To run the tool on each slice in the multidimensional raster and generate a multidimensional raster output, be sure to save the output to CRF.

    Supported input multidimensional dataset types include multidimensional raster layer, mosaic dataset, image service, and CRF.

Parameters

LabelExplanationData Type
Input Raster

The raster dataset to rotate.

Mosaic Layer; Raster Layer
Output Raster Dataset

The name, location, and format for the dataset you are creating. When storing a raster dataset in a geodatabase, do not add a file extension 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.

When storing the raster dataset in a file format, specify the file extension as follows:

  • .bilEsri BIL
  • .bipEsri BIP
  • .bmp—BMP
  • .bsqEsri BSQ
  • .dat—ENVI DAT
  • .gif—GIF
  • .img—ERDAS IMAGINE
  • .jpg—JPEG
  • .jp2—JPEG 2000
  • .png—PNG
  • .tif—TIFF
  • .mrf—MRF
  • .crf—CRF
  • No extension for Esri Grid
Raster Dataset
Angle

Specify a value between 0 and 360 degrees the raster will be rotated in the clockwise direction. To rotate the raster in the counterclockwise direction, specify the angle as a negative value. The angle can be specified as an integer or a floating-point value.

Double
Pivot Point
(Optional)

The point the raster will rotate around. If left blank, the lower left corner of the input raster dataset will serve as the pivot.

Point
Resampling Technique
(Optional)

Specifies the resampling technique that will be used. The default is Nearest.

The Nearest and Majority options are used for categorical data, such as a land-use classification. The Nearest option is the default. It is the quickest and does not change the pixel values. Do not use either of these options for continuous data, such as elevation surfaces.

The Bilinear and Cubic options are most appropriate for continuous data. It is recommended that you do not use either of these options with categorical data because the pixel values may be altered.

  • Nearest neighbor The nearest neighbor technique will be used. It minimizes changes to pixel values since no new values are created and is the fastest resampling technique. It is suitable for discrete data, such as land cover.
  • Bilinear interpolation The bilinear interpolation technique will be used. It calculates the value of each pixel by averaging (weighted for distance) the values of the surrounding four pixels. It is suitable for continuous data.
  • Cubic convolutionThe cubic convolution technique will be used. It calculates the value of each pixel by fitting a smooth curve based on the surrounding 16 pixels. This produces the smoothest image but can create values outside of the range found in the source data. It is suitable for continuous data.
  • Majority resamplingThe majority resampling technique will be used. It determines the value of each pixel based on the most popular value in a 4 by 4 window. It is suitable for discrete data.
String
Clipping Extent
(Optional)

The processing extent of the raster dataset. The source data will be clipped to the specified extent before rotation.

  • Current Display Extent Map View—The extent will be based on the active map or scene. This option is only available when there is an active map.
  • Extent of a Layer Layer—The extent will be based on an active map layer. Use the drop-down list to choose an available layer or use the Extent of data in all layers option to get the combined extent of all active map layers, excluding the basemap. This option is only available when there is an active map with layers.
  • Browse Browse—The extent will be based on an existing dataset.
  • Reset Extent Reset—The extent will be reset to the default value.
  • Manually entered coordinates—The coordinates must be numeric values and in the active map's coordinate system.

    The map may be using different display units

NameExplanationData Type
in_raster

The raster dataset to rotate.

Mosaic Layer; Raster Layer
out_raster

The name, location, and format for the dataset you are creating. When storing a raster dataset in a geodatabase, do not add a file extension 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.

(Optional)

Specifies the resampling technique that will be used. The default is Nearest.

  • NEAREST The nearest neighbor technique will be used. It minimizes changes to pixel values since no new values are created and is the fastest resampling technique. It is suitable for discrete data, such as land cover.
  • BILINEAR The bilinear interpolation technique will be used. It calculates the value of each pixel by averaging (weighted for distance) the values of the surrounding four pixels. It is suitable for continuous data.
  • CUBICThe cubic convolution technique will be used. It calculates the value of each pixel by fitting a smooth curve based on the surrounding 16 pixels. This produces the smoothest image but can create values outside of the range found in the source data. It is suitable for continuous data.
  • MAJORITYThe majority resampling technique will be used. It determines the value of each pixel based on the most popular value in a 4 by 4 window. It is suitable for discrete data.
