Multispectral classification may be performed using a

variety of methods, including:

algorithms based on parametric and nonparametric

statistics that use ratio- and interval-scaled data and

nonmetric methods that can also incorporate nominal

scale data;

the use of supervised or unsupervised classification

logic;

the use of hard or soft (fuzzy) set classification logic

to create hard or fuzzy thematic output products;

the use of per-pixel or object-oriented classification

logic, and hybrid approaches.
