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("C:/data/preston.img")

# Print some raster dataset properties
# 
print "Band Count:       %d" % desc.bandCount
print "Compression Type: %s" % desc.compressionType
print "Raster Format:    %s" % desc.format
