The Trihydro Corporation located in Laramie, Wyoming altered the extent, coordinate system and data format of this dataset. Alterations were made to meet the requirements set forth by the Wyoming Water Development Commission for the Platte River Basin Plan. See Supplemental Information under the Description section or Process Description under the Process Step for details.

Wyoming Geographic Information Science Center - Original digital National Wetland Inventory quadrangles converted into Arc/Info coverages with matching attributes.
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.
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.
This dataset is the National Wetlands Inventory data obtained from the Wyoming Geographic Information Science Center. The dataset's extent, coordinate system, and data format were altered. The dataset was clipped to the extents of the North and South Platte 4th level hydrologic unit code watershed boundaries. The coordinate system was changed to Lat/Long NAD 1927 and the data format was converted from an ESRI coverage to an ESRI shapefile. These data alterations occurred in the Winter of 2003 for use in the Wyoming Water Development Commission's Platte River Basin Plan.

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.

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.
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).
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.

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.

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.
NWI_CODE is the parent attribute, and its characters have been subdivided into other attributes for ease of selection. Two *.dbf files are included with the NWI data, type.dbf and class.dbf. The field in type.dbf SYSTEM_SUB describes the codes for the wetlands subsystem (ie riverine, lacustrine, palustrine, or upland). The field in class.dbf, CLASS, describes the codes for the wetlands class, (eg rock bottom, aquatic bed, emergent).
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).
