Abstract:
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.
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.
Supplemental Information: This Particular coverage represents the nwi data available for the Coquille Estuary.

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.

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).

Process Step:
Process Description:
Source quads were appended (tiled) together and then clipped to the Basin Detail: The NWI data does not cover the entire state, and the coverages here represent the full extent of the digital data at this time. The data was downloaded from the NWI ftp site and subsequently unzipped and tarred to produce .dlg and .att files. These files were then subjected to dlg2arc.aml, which was also downloaded from the ftp site. In this way, the initial coverages were reproduced. These files were then appended in ArcInfo to create one coverage for the 250K Coos Bay map. This appended coverage was
cleaned (1 1) to create a primary coverage. This was then divided into arc and polygon coverages, to preserve the full range of attribute data associated with the features.
This was necessary because the dissolve function did not recognize the arc attributes and as a result this information was lost in the process. By reselecting the line features, the arc attributes were preserved in a separate coverage. A new field named TYPE was added and populated with the NWI class for each polygon, to create the option of a simple legend in Arcview. The Polygon coverage was then clipped to the DEMIS estuary basin in ArcInfo, reprojected into Oregon Lambert, and exported from ArcInfo into an e00 and a shapefile.
