GIS Lookup: Detailed Data Layer Listing

Data Layer GraphicTitle: "National Wetlands Inventory - Line" (1999)
Description: NWI digital data files are records of wetlands location and classification as defined by the U.S. Fish & Wildlife Service. This dataset is one of a series available in 7.5 minute by 7.5 minute blocks containing ground planimetric coordinates of wetlands point, line, and area features and wetlands attributes. When completed, the series will provide coverage for all of the contiguous United States, Hawaii, Alaska, and U.S. protectorates in the Pacific and Caribbean. The digital data as well as the hardcopy maps that were used as the source for the digital data are produced and distributed by the U.S. Fish & Wildlife Service's National Wetlands Inventory project. Base map dates Range from Oct. 1981 to present. CGIA has compiled the 7.5 minute quadrangle extent digital files into river basin map extent files. These extents are stored as tiles in a GIS library. The NWI identifier is in in the condensed format in the polygon (area) attributes, and in a parsed format in the arc (line) attributes. Other wetland classification exist for North Carolina. The data provide consultants, planners, and resource managers with information on wetland location and type. The data were collected to meet U.S. Fish & Wildlife Service's mandate to map the wetland and deepwater habitats of the United States.
