Summary

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.

Description

--Zoom in and this layer will draw faster on the map--

This data set represents the extent, approximate location and type of wetlands and deepwater habitats in the United States and its Territories. These data delineate the areal extent of wetlands and surface waters as defined by Cowardin et al. (1979). The National Wetlands Inventory - Version 2, Surface Waters and Wetlands Inventory was derived by retaining the wetland and deepwater polygons that compose the NWI digital wetlands spatial data layer and reintroducing any linear wetland or surface water features that were orphaned from the original NWI hard copy maps by converting them to narrow polygonal features. Additionally, the data are supplemented with hydrography data, buffered to become polygonal features, as a secondary source for any single-line stream features not mapped by the NWI and to complete segmented connections. Wetland mapping conducted in WA, OR, CA, NV and ID after 2012 and most other projects mapped after 2015 were mapped to include all surface water features and are not derived data. The linear hydrography dataset used to derive Version 2 was the U.S. Geological Survey's National Hydrography Dataset (NHD). Specific information on the NHD version used to derive Version 2 and where Version 2 was mapped can be found in the 'comments' field of the Wetlands_Project_Metadata feature class. 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. This dataset should be used in conjunction with the Wetlands_Project_Metadata layer, which contains project specific wetlands mapping procedures and information on dates, scales and emulsion of imagery used to map the wetlands within specific project boundaries.

Supplemental information
Digital wetlands data are intended for use us with base maps and digital aerial photography at a scale of 1:12,000 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 or intended to represent legal or regulatory products. Questions or comments regarding the interpretation or classification of wetlands or deepwater habitats can be addressed by visiting http://www.fws.gov/wetlands/FAQs.html 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. For more informtion on the wetland classification codes visit http://www.fws.gov/wetlands/Data/Wetland-Codes.html . The U.S. Fish and Wildlife Service uses data standards to increase the quality and compatibility of its data. The standards used for the wetlands data can be found at: http://www.fws.gov/wetlands/Data/Data-Standards.html and include the FGDC Wetlands Mapping Standard, FGDC-STD-015-2009. 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 and Content Standard for Digital Geospatial Metadata (CSDGM) 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.

Measure description
Polygon and chain-node topology are present. Every polygon has a label.




Data quality report - Completeness omission
Measure description
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 of the 50 states, the District of Columbia, Puerto Rico, the Virgin Islands, Guam and Saipan. 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.




Data quality report - Quantitative attribute accuracy
Measure description
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 test results
Value All polygons are attributed.




Lineage

Process step
Description
The National Wetlands Inventory - Version 2, Surface Waters and Wetlands Inventory was derived using an ESRI Data Model with 481 logical and topological processes. Linear NWI features retained their original NWI Code and were buffered to specific widths based on the following rules: Palustrine = 6m, Riverine Perennial = 8m, Riverine Intermittent = 6m, Marine, Estuarine and Lacustrine = 8m. The NHDFlowline features were buffered to the width based on the FType field using the following general rules: CanalDitch = 4m, Intermittent = 6m and Perennial = 6m. The NHDFlowline features were coded with NWI Codes based on the following general rules: CanalDitch/aqueduct = R5UBFr, CanalDitch/all others = R5UBFx, Intermittent Stream = R4SBC, Perennial Stream = R5UBH. Further refinement of the NWI Codes was implemented based on spatial intersect with known NWI features and specific FCode information from the NHD dataset. Topological modifications were conducted to remove overlapping features. In general buffered NWI linears were clipped into NWI polygons and both the NWI polygons and buffered NWI linears were used to erase buffered NHDFlowlines. Further topological refinements were conducted within the the buffered linear feature layers based on intersections with known NWI features and using a hierarchy based on NWI Code Sub-system and Water Regime. For more specific information on the logical and topological processes involved in deriving this dataset visit: http://www.fws.gov/wetlands/Data/Wetlands-V2-Product-Summary.html




Process step
Description
This dataset is continually updated in various areas of the Nation with wetlands data from the USFWS, other federal, state and local agencies, tribes, non-governmental organizations and universities. To identify these updated areas review the Data Source layers on the Wetlands Mapper, Projects Mapper on the Mapper homepage, or the Wetlands Project Metadata featureclass that is included in the data downloads. The Wetlands Project Metadata feature class may also include a URL to link to a document that identifies project speciic techniques, source imagery and conventions used for that specific project. All data additions comply with the the FGDC Wetlands Mapping Standard, FGDC-STD-015-2009 and the Wetlands Classification Standard, which can be found at: http://www.fws.gov/wetlands/Data/Data-Standards.html .




Process step
Description
The National Wetlands Inventory - Version 2, Surface Waters and Wetlands Inventory was derived by retaining the wetland and deepwater polygons that compose the NWI digital wetlands spatial data layer and reintroducing any linear wetland or surface water features that were orphaned from the original NWI hard copy maps by converting them to narrow polygonal features. Additionally, the data are supplemented with hydrography data (high resolution NHD 931v210 or 931v220), buffered to become polygonal features, as a secondary source for any single-line stream features not mapped by the NWI and to complete segmented connections. Specific information on the NHD version used to derive Version 2 and where Version 2 was mapped can be found in the 'comments' field of the Wetlands_Project_Metadata feature class.




Process step
When the process occurred 2004-01-01
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. Further data improvements included the conversion of all old wetland codes that contained 'OW' to the new code containing 'UB', 'BB' to 'US', 'FL' to 'US', and 'SB' to 'US' except for 'R4SB' codes. Old Water Regimes were also changed, 'W' to 'A', 'Y' to 'C' and 'Z' to 'H'. All polygons labeled as 'OUT', 'No Data' and 'NP' were removed from the database.
