Using the Describe() function to return descriptive information about a raster image
Raster files also contain descriptive information that can be returned by the Describe()
function.
Getting ready
A raster dataset can also be described through the use of the Describe()
function. In this recipe, you will describe a raster dataset by returning its extent and spatial reference. The Describe()
function contains a reference to the general purpose Dataset
properties group and also contains a reference to the SpatialReference
object for the dataset. The SpatialReference
object can then be used to get detailed spatial reference information for the dataset.
