Summary
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".
Properties
| Property | Explanation | Data Type | 
| bandCount (Read Only) | The number of bands in the raster dataset. | Integer | 
| compressionType (Read Only) | The compression type. 
 | String | 
| format (Read Only) | The raster format. 
 | String | 
| permanent (Read Only) | Indicates the permanent state of the raster: False if the raster is temporary and True if the raster is permanent. | Boolean | 
| sensorType (Read Only) | The sensor type used to capture the image. | String | 
Code sample
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)
