The Florida Department of Environmental Protection Land Use Land Cover data classification types are originally taken from Florida Department of Transportation's "Florida land use, cover and forms classification system (FLUCCS)." The FLUCC's system is hierarchical; it includes four levels that build in terms of specificity: A Level 1 classification is the most general. It is a four-digit code in which the first integer in the code is assigned one of eight numbers: 1000 = Urban and Built Up class; 2000 = Agricultural; 3000 = Rangeland; 4000 = Upland Forests; 5000 = Water; 6000 = Wetlands; 7000 = Barren Land; and 8000 = Transportation, Communications, and Utilities. The second integer (and each successive integer) provides a sub classification of a higher specificity. For example, 2100 (Level II) class is Crop and Pasture Land, a subtype of the 2000 Agricultural class; 2150 (Level III) : Field Crops is a specific subtype of the 2100 Crop and Pasture Land subtype. Further, 2153 (Level IV) is a specific subtype of the 2150 class. Very few level 4 classifications have been chosen. This is so because discernment of the keys to classification for these classes typically require imagery of a higher resolution than our source imagery. The Level 4 designation is indicated in either the Land Use Code or Secondary Code Fields of the attribute table. A few classification types were added to accommodate needs that were specific to the water management districts.
