Mapping the Nation's Wetlands
The NWI data layer is a result of working with many partners and cooperators that have contributed to mapping the nation’s wetlands for more than 45 years. Cooperators include states, other federal agencies, tribal governments, regional and local governments, and nonprofit organizations. To date, over 165 organizations have contributed to the Wetlands Data Layer. NWI actively partners with entities interested in pursuing wetland and deepwater habitat mapping and analysis and can provide guidance and support throughout the life cycle of a wetland project(s).
Before submissions can be accepted into the national wetlands layer, data must comply with both the Federal Mapping and Classification Standards. NWI provides wetland data contributors with guidance and documentation pertaining to all federal requirements for compliant data submissions.
