Shift

Summary

Moves (slides) the raster to a new geographic location, based on x and y shift values. This tool is helpful if your raster dataset needs to be shifted to align with another data file.

Usage

  • The cell size of the output raster will be the same as that of the input raster.

  • The number of rows and columns in the output raster will be the same as those of the input raster, no matter what parameters are specified.

  • The coordinates of the lower left corner of the output raster will be offset from the input raster by the x and y shift coordinate values specified.

  • Using a negative shift x-coordinate value will shift the output to the left. A positive shift x-coordinate value will shift the output to the right. Using a negative shift y-coordinate value will shift the output down. A positive shift y-coordinate value will shift the output to the top.

  • The output raster dataset is nudged according to the location of the input snap raster, so the new shifted raster dataset can be aligned perfectly with another raster dataset.

  • Shift does not perform any resampling or warping.

  • 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.

Syntax

Shift(in_raster, out_raster, x_value, y_value, {in_snap_raster})
ParameterExplanationData Type
in_raster

The input raster dataset.

Mosaic Layer; Raster Layer
out_raster

Output raster dataset.

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
  • .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.

Raster Dataset
x_value

The value used to shift the x coordinates.

Double
y_value
