ETG_ClipRasterWithPolygons

Clip Raster with Polygons

Clips a raster dataset with the polygons of the input polygon feature class.

A raster with cell values equal to the cell values of the input raster, but only in the locations overlapping the clip polygons.
Areas outside of the clipping polygons are assigned a value of NODATA.

Input raster and clip polygons

Result raster

The output raster will have the extent of the intersection between the input raster extent and the clip dataset extent.
If the clip dataset is not with the same spatial reference as the input raster, it will be projected to the spatial referense of the raster and the clipping will be done with the projected features. If projection parameters can not be established, no output will be created and an error will be recorded in the Log file.
All raster cells with centers within the clipping polygons will preserve their value. All cells outside of the clipping polygons will be assigned a value of NODATA.
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

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, "ClipRasterWithPolygons", "input raster", "output raster", "clip dataset"])
.NET using ETSRun.exe	StartInfo.FileName = ETSPath StartInfo.Arguments = "ClipRasterWithPolygons" "input raster" "output raster" "clip dataset"

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.
