Generate Raster From Raster Function

Summary

Generates a raster dataset from an input raster function or function chain. The output raster format can be TIFF, GRID, IMAGINE, CRF (Cloud Raster Format), or MRF (Meta Raster Format).

Usage

• The tool is designed for raster processing and analysis in the cloud. Use raster functions (in-memory processing) to write the results generated to disk.

Syntax

GenerateRasterFromRasterFunction_management (raster_function, output_raster_dataset, {raster_function_arguments}, {raster_properties}, {format})

Parameter	Explanation	Data Type
raster_function	The name of a raster function, raster function JSON object, or function chain (in .rft.xml format).	File; String
output_raster_dataset	The output raster dataset. This dataset can be written to a local directory or saved in cloud storage as a URL.	Raster dataset
raster_function_arguments [[Name, Value],...] (Optional)	The parameters associated with the function chain. For example, if the function chain applies the Hillshade raster function, set the data source, azimuth and altitude.	Value Table
raster_properties [[Name, Value],...] (Optional)	The output raster dataset key properties, such as the sensor or wavelength.	String
format (Optional)	The output format. The default is CRF if the output_raster_dataset parameter is set to a URL. If you select a different output format, it will honor that extension.	String

Code sample

	out_raster_dataset="c:/temp/ndvitest.crf", 
	raster_function_arguments="Raster \\\\somemachine\\data\\test.tif; VisibleBandID 3;InfraredBandID 4", 
	format="CRF")
