Raster Dataset properties

Resumen

The Describe function returns the following properties for raster datasets. The Dataset property group is also supported. Single-band raster datasets also support the Raster Band property group.

For a raster dataset, the Describe dataType property returns a value of "RasterDataset".

Raster dataset properties example

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(r"C:\temp\FGDB.gdb\RD")

# 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)
