National Wetlands Inventory Polygon Data
This topical layer shows graphic representations of the type, size and location of the wetlands and deepwater habitats in the United States. These maps have been prepared from by the analysis of high altitude imagery in conjunction with collateral data sources and field work.
The Fish and Wildlife Service uses the Cowardin et al. (1979) definition of wetland. This definition is the standard for the agency, and is the national standard for wetland mapping, monitoring, and data reporting as determined by the Federal Geographic Data Committee on December 17, 1996
The Emergency Wetlands Resources Act of 1986 [16 U.S.C. 3931(a)] and its subsequent amendments, gave the Service specific goals and deadlines for producing hard copy and digital wetland maps for the conterminous United States, Alaska, Hawaii, and its Trust Territories. The principal focus was to produce topical wetland maps that are graphic representations of the type, size and location of all surface waters in the United States (wetlands and deepwater habitats). Within this context, the objective of mapping wetlands and deepwater habitats remains to produce reconnaissance level information on the location, type, size of these habitats such that they are accurate at the nominal scale of the 1:24,000 base map. The Service recognized the limitations of using remotely sensed information as the primary data source, and additionally, by policy, excluded some wetland types from its inventory. The Service neither designed nor intended the program to produce legal or regulatory products. Unintended use of the information or products is discouraged.
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.
This topical layer was compiled by the U.S. Fish and Wildlife Service.
The wetland information can also be viewed as part of The National Map available through the U.S Geological Survey.
Metadata:
What follows is very detailed technical information about this topical or thematic map layer. This is often called metadata. Metadata (or "data about data") describe the content, quality, condition, and other characteristics of data. Metadata are used to organize and maintain investments in data, provide information to data catalogs and clearinghouses, aid data transfers and to inform data users. The Federal Geographic Data Committee (FGDC) publishes the Content Standard for Digital Geospatial Metadata. Many organizations within and outside of the federal government have adopted the FGDC metadata standard and are using automated indexing and serving mechanisms to provide access to their holdings through the Internet.
The U. S. Fish and Wildlife Service has produced a Biological Metadata Standard (http://www.fws.gov/stand/standards/pr_biomet.html) that provides guidance for minimal documentation of spatial data files created by Service staff. Key elements of the metadata include the following:
* Identification_Information
* Data_Quality_Information
* Spatial_Data_Organization_Information
* Spatial_Reference_Information
* Entity_and_Attribute_Information
* Distribution_Information
* Metadata_Reference_Information

Description:
Abstract:
This data set represents the extent, approximate location and type of wetlands and deepwater habitats in the conterminous United States, Alaska, Hawaii, Puerto Rico and the Virgin Islands, and the Pacific Trust Territories. These data delineate the areal extent of wetlands and surface waters as defined by Cowardin et al. (1979).
Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and near shore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go undetected by aerial imagery.
By policy, the Service also excludes certain types of "farmed wetlands" as may be defined by the Food Security Act or that do not coincide with the Cowardin et al. definition. Contact the Service's Regional Wetland Coordinator for additional information on what types of farmed wetlands are included on wetland maps.
Purpose:
The present goal of the Service is to provide the citizens of the United States and its Trust Territories with current geospatially referenced information on the status, extent, characteristics and functions of wetlands, riparian, deepwater and related aquatic habitats in priority areas to promote the understanding and conservation of these resources.
Supplemental_Information:
The wetland maps were produced as topical overlays using U.S. Geological Survey topographic maps as the base. The hard copy product is a composite map showing topographic and planimetric features from the USGS map base and wetlands and deepwater habitats from the Service's topical overlay. Thus, the data are intended for use in publications, at a scale of 1:24,000 or smaller. Due to the scale, the primary intended use is for regional and watershed data display and analysis, rather than specific project data analysis. The map products were neither designed nor intended to represent legal or regulatory products.
Comments regarding the interpretation or classification of wetlands or deepwater habitats can be directed to the U.S. Fish and Wildlife Service, Division of Federal Program Activities, Branch of Habitat Assessment <http://www.fws.gov/duspit/contactus.htm>
These data were developed in conjunction with the publication Cowardin, L.M., V. Carter, F.C. Golet, and E.T. LaRoe. 1979. Classification of Wetlands and Deepwater Habitats of the United States. U.S. Department of the Interior, Fish and Wildlife Service, Washington, DC. FWS/OBS-79/31. Alpha-numeric map codes have been developed to correspond to the wetland and deepwater classifications described.
These spatial data are not designed to stand alone. They form topical overlays to the U.S. Geological Survey 1:24,000 or 1:25,000 scale topographic quadrangles. Note that coastline delineations were drawn to follow the extent of wetland or deepwater features as described by this project and may not match the coastline shown in other base maps.
Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government.
Although this Federal Geographic Data Committee-compliant metadata file is intended to document the data set in nonproprietary form, as well as in Arc/INFO format, this metadata file may include some Arc/INFO-specific terminology.

The source data was checked using standard review procedures. Attributes were checked by using visual inspection as well as automated verification routines. Quality of the attribute information varies with age and mapping protocols used when individual maps were prepared
Quantitative_Attribute_Accuracy_Assessment:
Attribute_Accuracy_Value: All polygons are attributed.
Logical_Consistency_Report:
Polygon and chain-node topology are present. Every polygon has a label.
Completeness_Report:
This data set represents the extent of wetlands and deepwater habitats that can be determined with the use of remotely sensed data and within the timeframe for which the maps were produced. Wetlands are shown in all 50 states and the District of Columbia, Puerto Rico, the US Virgin Islands, and the Pacific Trust Territories. The accuracy of image interpretation depends on the quality of the imagery, the experience of the image analysts, the amount and quality of the collateral data, and the amount of ground truth verification work conducted.
There is a margin error inherent in the use of imagery, thus detailed on-the-ground inspection of any particular site, may result in revision of the wetland boundaries or classification, established through image analysis.
Wetlands or other mapped features may have changed since the date or the imagery and/or field work. There may be occasional differences in polygon boundaries or classifications between the information depicted on the map and the actual conditions on site.

Process_Description:
Original stable base hard copy maps of wetland and deepwater habitats were created based on USGS state and quadrangle boundaries. These maps were converted to digital files using various software packages (WAMS, ARC and others). The digital files were stored as ESRI Import/Export files corresponding to a single 1:24,000 USGS quadrangle. These digital files were imported and converted to ESRI Coverage format and checked for topological and attribute errors. All coverages were converted from a UTM map projection to an Alber's Equal Area map projection and the horizontal datum was converted from NAD27 to NAD83 were necessary. Polygons attributed as "Uplands" were removed from the dataset and polygons were merged at quadrangle boundaries where the quadrangle line divided polygons with the same attribute. The data was loaded into a seamless SDE geodatabase for the conterminous United States. These steps were conducted using both Arc Macro Language (AML) and ArcMap editing tools. All point data from the original ESRI Coverages were buffered by 11.28 meters (1/10 of an acre) and incorporated into this polygon feature class. Linear features from the original ESRI Coverages were merged at quadrangle boundaries where the quadrangle line divided lines with the same attribute. Linear data is stored in a separate feature class.
Further data improvements included the conversion of all old wetland codes that contained 'OW' were converted to 'UB'. All polygons labeled 'OUT', 'No Data' and 'NP' were removed from the database.

The digital files were stored as ESRI Import/Export files corresponding to a single 1:24,000 USGS quadrangle. These digital files were imported and converted to ESRI Coverage format and checked for topological and attribute errors. All coverages were converted from Michigan GeoRef Oblique Mercator projection to an Alber's Equal Area map projection. Polygons attributed as "Uplands" were removed from the dataset and polygons were merged at quadrangle boundaries where the quadrangle line divided polygons with the same attribute. The data was loaded into a seamless SDE geodatabase for the conterminous United States. These steps were conducted using both Arc Macro Language (AML) and ArcMap editing tools.
Codes that contained 'OW' were converted to 'UB'. All polygons labeled as 'OUT', 'No Data', '999' and 'NP' were removed from the database. Some codes in this dataset were converted to conform to the original Cowardin naming convention. An Excel spreadsheet of the code changes is available at:
