A classifier is described that makes use of multitemporal data to produce an accurate ground cover thematic classification map. Ground cover types are considered as stochastic systems having nonstationary Gaussian processes as input and temporal variation of reflected and emitted electromagnetic energy as output. Then, by assumption that the behavior of these stochastic systems are governed by first-order Markov processes, multitemporal information is utilized. As a result of this approach for characterizing multitemporal data, a new processor, the Markov classifier, is developed. Experimental results from Landsat Multispectral Scanner (MSS) data are included which show significantly better performance than the maximum likelihood and cascade pixel classifiers.
