Rescale (Data Management)

Summary

Resizes a raster by the specified x and y scale factors.

Usage

  • The output size is multiplied by the scale factor for both the x and y directions. The number of columns and rows stays the same in this process, but the cell size is multiplied by the scale factor.

  • The scale factor must be positive.

  • A scale factor greater than one means the image will be rescaled to a larger dimension, resulting in a larger extent because of a larger cell size.

  • A scale factor less than one means the image will be rescaled to a smaller dimension, resulting in a smaller extent because of a smaller cell size.

  • 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.

Parameters

LabelExplanationData Type
Input Raster

The input raster.

Mosaic Layer; Raster Layer
Output Raster Dataset

The output raster dataset.

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

  • .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

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 in the geoprocessing Environments.
