Raster Dataset properties

Résumé

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("Permanent:        %s" % desc.permanent)
print("Sensor Type:      %s" % desc.sensorType)
