- Description:
- Abstract:
- NWI digital data files are records of wetlands location and classification as defined by
the U.S. Fish & Wildlife Service. This data set 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.
- Purpose:
- 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.

- Federal, State, and local regulatory agencies with jurisdiction over wetlands may define
and describe wetlands in a different manner than that used in this inventory. There is no
attempt, in either the design or products of this inventory, to define the limits of
proprietary jurisdiction of any Federal, State, or local government or to establish the
geographical scope of the regulatory programs of government agencies. Persons intending to
engage in activities involving modifications within or adjacent to wetland areas should
seek the advice of appropriate Federal, State, or local agencies concerning specified
agency regulatory programs and proprietary jurisdictions that may affect such activities.

- Native_Data_Set_Environment:
- NWI uses Wetlands Analytical Mapping System (WAMS) software version 4.06 running under
the SUNOS 4.x operating system to digitize wetlands information.
- Data_Quality_Information:
- Attribute_Accuracy:
- Attribute_Accuracy_Report:
- Attribute accuracy is tested by manual comparison of the source with hard copy printouts
and/or symbolized display of the digital wetlands data on an interactive computer graphic
system. In addition, WAMS software (USFWS-NWI) tests the attributes against a master set
of valid wetland attributes.
- Logical_Consistency_Report:
- 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).
- Completeness_Report:
- 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 data set.

- Horizontal_Positional_Accuracy:
- Horizontal_Positional_Accuracy_Report:
- Horizontal positional accuracy for the digital data is tested by visual comparison of
the source with hard copy plots.

- source material from which compiled wetlands location and classification are digitized
- Process_Step:
- Process_Description:
- NWI maps are compiled through manual photo interpretation 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 labeled. Quality control steps occur
throughout the photo interpretation, map compilation, and map reproduction processes.

- Process_Step:
- Process_Description:
- Digital wetlands data were manually digitized 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. 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 data were checked for position by comparing plots of the digital data to
the source material.

- Detailed_Description:
- Entity_Type:
- Entity_Type_Label: wetland
- Entity_Type_Definition:
- Wetlands are lands transitional between terrestrial and aquatic systems where the water
table is usually at or near the surface or the land is covered by shallow water. For
purposes of this classification wetlands must have one or more of the following three
attributes: 1) at least periodically, the land supports predominantly hydrophytes; 2) the
substrate is predominantly undrained hydric soil; and 3) the substrate is non-soil and is
saturated with water or covered by shallow water at some time during the growing season of
each year.

- Attribute:
- Attribute_Label: wetland classification
- Attribute_Definition:
- The wetland classification system is hierarchical, with wetlands and deepwater habitats
divided among five major systems at the broadest level. 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).

- Fees:
- Digital Form - The online copy of the DLG data set may be retrieved via ftp at no
charge. For delivery of digital data on magnetic tape, the prices are: purchased by single
7.5 minute quad unit: $40 per dataset; purchased in groups of 2 to 6: $20 per dataset;
purchased in groups of 7 or more: $90 base fee plus $7 per dataset. Non-digital Form -
$3.50 per diazo paper map; $5.25 per diazo mylar map.
- Ordering_Instructions:
- For digital data orders on 3.5" floppy disk, a maximum order of 10 quads is
allowed. Data may be ordered in latitude/longitude or State Plane Coordinate System
coordinates (Universal Transverse Mercator coordinates are standard). Latitude/longitude
coordinates are not available with GRASS format. For this service, the user must order
data through USGS-ESIC for delivery on magnetic media. Please specify the desired
coordinate system when ordering. Non-digital form: specify wetlands overlay or wetlands
overlay composited with USGS base map.
- Technical_Prerequisites:
- Check NWI's ftp site, maps directory for an explanation of the wetland codes. Check
NWI's ftp site, software directory for a program that will parse the wetland codes to
fixed length format. Check NWI's ftp site, software directory for an AML to convert NWI
DLG files to ARC/INFO coverages.
