  • a The minimum mapping unit for the National Wetlands Inventory database is one to three acres. Thus, the wetland area calculated from this dataset may exceed the total land area.

  • b The minimum mapping unit for the C-CAP land cover database is 30 m pixels (1/4 acre). Thus, the cultivated land area calculated from this dataset may exceed the total land area.
