U.S. Fish & Wildlife Service, National Wetlands Inventory 19990518 vector digital data St.Petersburg, Florida U.S. Fish & Wildlife Service, National Wetlands Inventory NCCGIA distributes this dataset 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. 24,000-scale NWI files were joined to create 1:100,000-scale tiles which were then joined to created river basin tiles. The tile names, abbreviations and approximate file sizes are list here. >River Basin ABBREV MB >Broad brd 2 >Cape Fear cpf 60 >Catawba ctb 8 >Chowan cho 8 >French Broad frb 2 >Hiwassee hiw 1 >Little Tennessee ltn 1 >Lumber lbr 24 >Neuse neu 39 >New new 2 >Pasquotank pas 13 >Roanoke roa 19 >Savannah sav no digital data >Tar-Pamlico tar 31 >Watauga wat 1 >White Oak wok 10 >Yadkin yad 19 >Revisions and updates to this layer include: >system filename: /library/librb/tiles/(rivbasabbrev)/nwi >filesizes range from 1 - 60 mb per tile >4.) directory: nwi_599 filenames: (rivbas)nwi599 >The May 1999 updates to this layer consisted of combining the >100k tiles into river basin files and stripping out the quadrangle >neatlines.

In addition, WAMS software (USFWS-NWI) tests the attributes against a master set of valid wetland attributes. Polygons intersecting the neatline are closed along the border. Segments making up the outer and inner boundaries of a polygon tie end-to-end to completely enclose the area. Line segments are a set of sequentially numbered coordinate pairs. No duplicate features exist nor duplicate points in a data string. Intersecting lines are separated into individual line segments at the point of intersection. Point data are represented by two sets of coordinate pairs, each with the same coordinate values. All nodes are represented by a single coordinate pair which indicates the beginning or end of a line segment. The neatline is generated by connecting the four corners of the digital file, as established during initialization of the digital file. All data crossing the neatline are clipped to the neatline and data within a specified tolerance of the neatline are snapped to the neatline. Tests for logical consistency are performed by WAMS verification software (USFWS-NWI). Once the 7.5 minute extents are map joined into river basin extents, the data is built for topology. No edits have been made since the last build or clean. All photo-interpretable wetlands are mapped. In the treeless prairies, 1/4 acre wetlands are mapped. In forested areas, small open water and emergent wetlands are mapped. In general, the minimum mapping unit is from 1 to 3 acres depending on the wetland type and the scale and emulsion of the source aerial photography. In regions of the country where evergreen forested wetlands predominate, wetlands smaller than 3 acres may not be mapped. Thus, a detailed on the ground and historical analysis of a single site may result in a revision of the wetland boundaries established through photographic interpretation. In addition, some small wetlands and those obscured by dense forest cover may not be included in this dataset. The positional accuracy of the data delivered by the NWI program is significantly altered at CGIA. This data was reprojected to NAD83, State Plane, Meters using ESRI's projection routine in ARC/INFO version 7.2.

NWI maps are compiled through manual photointerpretation of NHAP or NAPP aerial photography supplemented by Soil Surveys and field checking of wetland photo signatures. Delineated wetland boundaries are manually transferred from interpreted photos to USGS 7.5 minute topographic quadrangle maps and then manually labelled. Quality control steps occur throughout the photointerpretation, map compilation, and map reproduction processes. NWI1 and NWI2 data were used in this 1994 process. Digital wetlands data are either manually digitized or scanned from stable-base copies of the 1:24,000 scale wetlands overlays registered to the standard U.S. Geological Survey (USGS) 7.5 minute quadrangles into topologically correct data files using Wetlands Analytical Mapping System (WAMS) software. Files contain ground planimetric coordinates and wetland attributes. The quadrangles were referenced to the North American Datum of 1927 (NAD27) horizontal datum. The scanning process captured the digital data at a scanning resolution of at least 0.001 inches; the resulting raster data were vectorized and then attributed on an interactive editing station. Manual digitizing used a digitizing table to capture the digital data at a resolution of at least 0.005 inches; attribution was performed as the data were digitized. The determination of scanning versus manual digitizing production method was based on feature density, source map quality, feature symbology, and availability of production systems. The data were checked for position by comparing plots of the digital data to the source material.

They were then map joined into USGS 100 k map extent files. These had the neatlines dissovled, and the data was joined into a statewide file.

The five systems include Marine (open ocean and associated coastline), Estuarine (salt marshes and brackish tidal water), Riverine (rivers, creeks, and streams), Lacustrine (lakes and deep ponds), and Palustrine (shallow ponds, marshes, swamps, sloughs). Systems are further subdivided into subsystems which reflect hydrologic conditions. Below the subsystem is the class which describes the appearance of the wetland in terms of vegetation or substrate. Each class is further subdivided into subclasses; vegetated subclasses are described in terms of life form and substrate subclasses in terms of composition. The classification system also includes modifiers to describe hydrology (water regime), soils, water chemistry (pH, salinity), and special modifiers relating to man's activities (e.g., impounded, partly drained). >NWI.PAT Polygon Attribute Table >COL ITEM NAME WDTH OPUT TYP N.DEC ALTERNATE NAME >1 AREA 4 12 F 3 >5 PERIMETER 4 12 F 3 >9 NWI# 4 5 B - >13 NWI-ID 4 5 B - >17 NWI-NAME 20 20 C - >37 FIPS 3 3 I - > >NWI.AAT Arc Attribute Table >COL ITEM NAME WDTH OPUT TYP N.DEC ALTERNATE NAME >1 FNODE# 4 5 B - >5 TNODE# 4 5 B - >9 LPOLY# 4 5 B - >13 RPOLY# 4 5 B - >17 LENGTH 4 12 F 3 >21 NWI# 4 5 B - >25 NWI-ID 4 5 B - >29 NWI-NAME 20 20 C - >49 NWI-SYSTEM 2 2 C - >51 NWI-CLASS 7 7 C - >58 NWI-REGIME 3 3 C - >61 NWI-TITAL 1 1 C - >62 NWI-CHEMISTRY 1 1 C - >63 NWI-SOIL 1 1 C - >64 NWI-SPECIAL 1 1 C - >65 FIPS 3 3 I - Cowardin, L.M., V.
