ETG_SmoothRaster

Smooth Raster

Smooth a raster using Gaussian function on 3 x 3 or 5 x 5 neighborhood. Read more about Gaussian smoothing here.

A profile of a raster before and after smoothing.

The output raster will always be a 32 bit floating raster.
The input format accepted are file based rasters - ERDAS IMAGINE or Tagged Image File Format (TIFF).
The .NET ToolBox for ArcGIS Desktop accepts also FileGDB Raster inputs.
For file based rasters initially the name of the output raster define the raster format:
- .img extension (for example raster1.img) - ERDAS IMAGINE image.
- .tif extension (for example raster1.tif) - TIFF image.
- The initial output raster format can be changed by selecting the desired output in the dialog.

Parameters

Expression	Explanation
Function Name	SmoothRaster
<input raster>	A String representing the input raster dataset.
<output raster>	A String - the full name of the output raster.
<neighborhood size>	An Integer indicating the neighborhood size to be used. Valid inputs are 3 and 5.

ETSPath used in the table below is the full path to ETSRun.exe (E.G. "C:\Program Files\ETSpatial Techniques\ETSurface\ETSRun.exe")

Language	Syntax
Python	subprocess.call([ETSPath, "SmoothRaster", "input raster", "output raster", "neighborhood size"])
.NET using ETSRun.exe	StartInfo.FileName = ETSPath StartInfo.Arguments = "SmoothRaster" "input raster" "output raster" "neighborhood size"
.NET using ETSOutX.dll	SmoothRaster(input raster, output raster, neighborhood size)
ArcPy	arcpy.SmoothRaster("input raster", "output raster", "neighborhood size")

Notes:

<> - required parameter
{} - optional parameter
See examples for Python , .NET or ArcPy
The argument separator for StartInfo.Arguments is space. If a string might contain a space, you need to double quote it.
