ETG_ResampleRaster

Resample Raster

Alters a raster by changing the cell size and/or extent. The extent can be imported from an existing dataset - feature class, raster or TIN.

Input raster
Output raster name and format.
Cell size of the output raster.
A String indicating whether the extents of the output will be taken from the input raster, from a reference dataset or a custom extent is specified.
Reference dataset (feature, raster or TIN).
Custom extent to be used - X min, X max, Y min, Y max
Resampling method
- Nearest Neighbor - most appropriate for discrete data
- Bilinear Interpolation - most appropriate for continuous data

A raster with cell size and extent according to user input. The resampling method is "Nearest Neighbour" meaning that the value of the cell will be according to the nearest cell center of the source raster.

If a custom extent is specified, the output raster will have the extent of the intersection between the input raster extent and the custom extent.
If a reference dataset is specified, the output raster will have the extent of the intersection between the input raster extent and the extent of the reference dataset.
If a reference dataset is specified and it is not with the same spatial reference as the input raster, its extent will be projected to the spatial referense of the input raster and the clipping will be done with the projected extent.
The input format accepted are file based rasters - ERDAS IMAGINE or Tagged Image File Format (TIFF).
The Python ToolBox for ArcGIS Desktop and ArcGIS Pro accepts also FileGDB Raster and ESRI GRID 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	ResampleRaster
<input raster>	A String - the full path to the input raster dataset.
<output raster>	A String - the full name of the output raster.
<cell size>	A Double representing the cell size.
{extent from}	A String indicating where the extents of the output will be taken from. "S" means that the extent of the input raster will be used, "R" means that the extent will be taken from the Reference Dataset, "C" means that a custom extent is specified in the last 4 parameters.
{reference dataset}	A String - the full path to the reference dataset
{MinX}	A Double - minimum X of the output extent.
{MaxX}	A Double - maximum X of the output extent.
{MinY}	A Double - minimum Y of the output extent.
{MinX}	A Double - maximum Y of the output extent.
{Method}	A String - the resampling method to be used. Valid values - "NEAREST" for Nearest Neighbor (this is the default) and "BILINEAR" for Bilinear Interpolation .

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, "ResampleRaster", "input raster", "output raster", "cell size", "extent from", "reference dataset", "MinX", "MaxX", "MinY", "MaxY", "Method"])
.NET using ETSRun.exe	StartInfo.FileName = ETSPath StartInfo.Arguments = "ResampleRaster" "input raster" "output raster" "cell size" "extent from" "reference dataset" "MinX" "MaxX" "MinY" "MaxY" "Method"
.NET using ETSOutX.dll	ResampleRaster(input raster, output raster, cell size, extent from, reference dataset, MinX, MaxX, MinY, MaxY, Method)
ArcPy	arcpy.ResampleRaster("input raster", "output raster", "cell size", "extent from", "reference dataset", "MinX", "MaxX", "MinY", "MaxY", "Method")

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.
