Smooth Raster
Open Table of Contents ToolBox Implementation
Smoothes a raster using Gaussian function on 3 x 3 or 5 x 5 neighborhood.

Read more about Gaussian smoothing  here

Inputs:

  • Input floating point raster dataset
  • Output raster name and format
  • Neighborhood size - 3 x 3 or 5 x 5

Example:

A profile of a raster before and after smoothing

Output:

  • A floating point raster.

Notes:

  • Initially the name of the output raster defines the raster format
    • no extension specified - ESRI binary GRID
    • .img extension (for example raster1.img) - ERDAS IMAGINE image.
    • .tif extension (for example raster1.tif - Tagged Image File Format (TIFF) image.
  • The initial output raster format can be changed by selecting the desired output in the dialog.
  • Currently only file based rasters are supported. Rasters cannot be stored in a GeoDatabase. After you get the desired result, you can export the raster to a GeoDatabase using the standard ArcGIS tools.
  • The input raster must be in a projected coordinate system.

Command line syntax

ETS_GPSmoothRaster <Input Raster>  <Out Raster> <Neighborhood>

Parameters

Expression Explanation
<Input Raster> A Raster dataset or Raster layer
<Out Raster> A String - the full name of the output raster (A raster with the same full name should not exist). The output raster type depends on the extension of the output file(see Notes above)
<Neighborhood> A String indicating the neighborhood to be used. Valid inputs "3x3" and "5x5"

Scripting syntax

ETS_GPSmoothRaster (Input Raster,  Out_Raster, Neighborhood)
