A Probabilistic Approach to Environmental Change Detection with Area-Class Map Data’s surface. Such comparisons are subject to error from a variety of sources including uncertainty in surveyed location, registration of map overlays, classification of land cover, application of the classification system and variation in degree of generalization. Existing geographical information sy
