1.2.3 Description Abstract What is some general information about the data set? 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 a source for the digital data, are produced and distributed by the U.S. Fish & Wildlife Service’s National Wetlands Inventory project. Purpose: Why was this data set created? 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.

(These access constraints may be applied to assure the protection of privacy or intellectual property.) None 1.8 Use Constraints: Are there any restrictions and legal prerequisites for using the data set after access is granted? 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. 2. 2.1 2.1.1

Data Quality Information
Attribute Accuracy: Attribute Accuracy Report: How accurate are the attributes and how was this determined? 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: What is the fidelity of relationships encoded in the data structure of the digital spatial data? What tests were performed and what were the results of the tests? (For ARC data, an example is: ARC-node topology exists.) 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 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: What selection criteria and definitions were used? What other relevant mapping rules were used? (For example, geometric thresholds such as minimum area or minimum width shall be reported. Describe the relationship between the objects presented and the abstract universe of all such objects.) All photo-interpretable wetlands are mapped. In the treeless prairies, ¼ 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. Positional Accuracy 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. Lineage What sources have contributed to your data set? (Repeat Source Citation and Citation Information for each source used. Also, you may repeat Source Time Period of Content, Time Period Information as many times as needed.) Source Information What type of information from these sources was used? (Give the list of sources and a brief statement about the information contributed by each. Only go as far back as you feel is necessary. You may not need to document every source that produced the sources that you used.)

( For example, on a 1:24,000-scale map, the Source Scale Denominator is 24000. The domain is > 1.) 65000 Type of Source Media: What is the medium of the source data set? (For example: the Source Media could be paper, CD-ROM, chart, online, magnetic tape, etc.) Black and white aerial photograph film transparency Source Time Period of Content: What is the time period for which the source data Single Date/Time Calendar Date: 198811 Source Currentness Reference: What is the basis on which the source time period of content
information was determined? (Examples are ground condition or publication date.)
Source photography date Source Citation Abbreviation: What is a short-form alias for the source citation? NWI1a Source Contribution: What information did the source contribute to the data set? Aerial photo from which wetlands spatial and attribute information are interpreted Process Step: What was the process used to create the data set? (Be sure to include all sources in your 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 USGFS 7.5 minute topographic quadrangle maps and then manually labeled. Quality control steps occur throughout the photointerpretation, map compilation, and map reproduction processes.
