Detailed Description

A raster band description.

The raster band describes how to interpret (and use) values that can be associated to each element of a raster, in one given dimension (e.g. a band of multi-hiperspectral remote sensing image). Each instance of this class refers to a particular dimension. This implementation defines a set of information commonly used to describe any raster.
