Table 4.
Comparison of total land use and land cover estimates and net change (gain or loss) between the NAIP-derived data and an eight-class NLCD scheme for Atlanta, Charlotte, and Raleigh.
We merged developed low, medium, and high intensity into the impervious class and changed developed open-space to managed clearing, and combined the percent impervious proportion of the developed types into the impervious class and merged the remaining proportion with herbaceous land cover to create managed clearings. Missing values indicate no comparison.
