An unsupervised classification of a LANDSAT Thematic Mapper (TM) scene of the Great Smoky Mountains National Park was done using all 7 spectral bands. The resulting TM class values for pixels ground-referenced to 128 forest productivity plots were extracted from the scene and paired with the plots' productivity values. The paired TM class/productivity values revealed significant differences in forest productivity between TM classes. On this basis the TM classes were reassigned to three productivity classes and a digitized forest productivity map of the entire TM scene generated. Using a Geographic Information System (GIS), this map was then overlaid with digitized topography and disturbance maps. Patterns of forest productivity were evaluated in reference to historic land disturbances and topography. Productivity information indices were calculated for each disturbance type.
