Raster Dataset properties

概要

The Describe function returns the following properties for Raster Datasets. Dataset Properties are also supported. Single-band raster datasets also support Raster Band Properties.

A Raster Dataset returns a dataType of "RasterDataset".

Raster Dataset properties example (stand-alone script)

The following stand-alone script displays some properties for a raster dataset. 

import arcpy

# Create a Describe object from the raster dataset
#
desc = arcpy.Describe("\\cacheqa1\Datasets\temp\FGDB.gdb\hrrr1")

# Print some raster dataset properties
# 
print "Band Count:       %d" % desc.bandCount
print "Compression Type: %s" % desc.compressionType
print "Raster Format:    %s" % desc.format
print("Processing Templates: %s" % desc.processingTemplates)
print("Default Processing Templates: %s" % desc.defaultprocessingTemplates)
print("DimensionNames: %s" % desc.dimensionNames)
print("DimensionValues: %d" % desc.Values)
print("MultidimensionalInfo: %s" % desc.multidimensionalInfo)
