ETG_RasterAspect

Raster Aspect

Calculates the aspect (the direction in which slope faces) of each cell of the input raster in degrees.Read more about Aspect and its importance here

Source Elevation raster

Result Aspect raster (Degrees option used)

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 - image.
- The initial output raster format can be changed by selecting the desired output in the dialog.

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

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.
