Summary
Turns a raster dataset around a specified pivot point.
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 your output to BIL, BIP, BMP, BSQ, DAT, Esri Grid , GIF, IMG, JPEG, JPEG 2000, PNG, TIFF, MRF, CRF, or any geodatabase raster dataset.
When storing your raster dataset to a JPEG file, a JPEG 2000 file, or a geodatabase, you can specify a Compression Type and Compression Quality in the 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.
Syntax
Rotate(in_raster, out_raster, angle, {pivot_point}, {resampling_type}, {clipping_extent})| Parameter | Explanation | Data 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. When storing the raster dataset in a file format, you need to specify the file extension:
| 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_type (Optional) | The resampling algorithm to 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 since it is the quickest and also because it will not change the cell values. Do not use either of these for continuous data, such as elevation surfaces. The Bilinear option and the Cubic option are most appropriate for continuous data. It is recommended that neither of these be used with categorical data because the cell values may be altered. | String |
clipping_extent (Optional) | The processing extent of the raster dataset. The source data will be clipped to the specified extent before rotation. | Extent |
