Description:
Abstract:
NWI digital data files are records of wetlands location and classification as defined by the U.S. Fish & Wildlife Service.  This dataset is a compilation of the 7.5 minute blocks containing ground planimetric coordinates of wetlands point, line, and area features and wetlands attributes for Chester County. 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 and Wildlife Service's National Wetlands Inventory project.
Purpose:
The data provide consultants, planners, and resource managers with information on wetland location and type in the form of an ArcView Shapefile. The data were collected to meet U.S. Fish & Wildlife Service's mandate to map the wetland and deepwater habitats of the United States.

Use_Constraints:
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.

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 dataset.

Process_Step:
Process_Description:
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.

Process_Step:
Process_Description:
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 quads 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.

Entity_Type:
Entity_Type_Label: SDE.ADD1.ChesterCountyWetlandsPolygon
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.

Overview_Description:
Entity_and_Attribute_Overview:
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).
