This document directs the digital mapping of wetland mapping, ensuring the accurate mapping and classifications of wetlands. The mapping standard is used for all wetland mapping nationally, including Federal Agencies, States, Tribes, especially if that mapping data will be uploaded into NWI/The National Map as a data layer. Specifically, if Federal funding is involved, then use of the proposed Standard is required. For all other efforts, use of the standard is strongly encouraged.
