Land Cover

Land cover was mapped at 30-m resolution from classification of 1993 and 1994 Landsat thematic Mapper satellite imagery. Bands 2,3,4, and 5 of the imagery and a Tassel Cap transformation were used in an iterative unsupervised clustering algorithm. Labeling of the spectral clusters with vegetation associations followed The Nature Conservancy/ UNESCO, Southeastern Region classification scheme. This hierarchical, ecologically based classification scheme delineates plant-associations in the southeast United States. The UNESCO classification scheme is the basis for the National Vegetation Classification Standard adoption by the Federal Geographic Data Committee. Labeling was assisted with auxiliary information from South Florida Water Management District land use/ land cover maps, National Wetlands Inventory maps, SSURGO soils maps, Everglades National Park and Big Cypress National Preserve vegetation surveys and photo interpreted points from low altitude aerial videography.
