        methodology: NLCD is produced by the Multi-Resolution Land Characteristics
          (MRLC) Consortium using Landsat imagery and ancillary data. Classification
          uses a decision-tree approach with training data.
        accuracy: Overall accuracy ~90% for land cover (Anderson Level II).
