GENERAL DESCRIPTION:
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). 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_V1 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.

USER NOTES:
Polygon and chain-node topology are present. Every polygon has a label.
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 for the state of Florida.  
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.
GeoPlan relied on the integrity of the attribute information within
the original data.
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 information 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.

The wetland classification system is hierarchical, with wetlands and 
deepwater habitats divided among five major systems at the broadest 
level.

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.

None. Precautions - 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. Acknowledgement of the U.S. Fish and Wildlife 
Service and (or) the National Wetlands Inventory would be appreciated in 
products derived from these data.

A note about data scale: 

Scale is an important factor in data usage.  Certain scale datasets
are not suitable for some project, analysis, or modeling purposes.
Please be sure you are using the best available data. 

1:24000 scale datasets are recommended for projects that are at the
county level.
1:24000 data should NOT be used for high accuracy base mapping such
as property parcel boundaries.
1:100000 scale datasets are recommended for projects that are at the
multi-county or regional level.
1:125000 scale datasets are recommended for projects that are at the
regional or state level or larger.

Vector datasets with no defined scale or accuracy should be
considered suspect. Make sure you are familiar with your data
before using it for projects or analysis. Every effort has been
made to supply the user with data documentation. For additional
information, see the References section and the Data Source Contact
section of this documentation. For more information regarding
scale and accuracy, see our webpage at:

DATA LINEAGE SUMMARY:
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' 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.
Process Date: 2004

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 specific techniques, source imagery and conventions used for that specific project. All data additions comply with 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 Date: Ongoing
This data was obtained in shapefile format via download from the USFWS National Wetlands Inventory website (http://www.fws.gov/wetlands/Data/State-Downloads.html) on June 10, 2016. When received, data was in the following projection: NAD_1983_Albers. The shapefile was projected to FGDL Albers HARN. Fields deleted included: ACRES, SHAPE_Length and SHAPE_Area. Fields added included: SYSTEM, SYSTEM_D, SUBSYSTEM, SUBSYSTEM_D, CLASS1, CLASS1_D, SUBCLASS1, SUBCL1_D, CLASS2, CLASS2_D, SUBCLASS2, SUBCL2_D, WATER1, WATER1_D, WATER2, WATER2_D, CHEMISTRY1, CHEMIST1_D, CHEMISTRY2, CHEMIST2_D, SOIL, SOIL_D, SPECIAL1, SPECIAL1_D, SPECIAL2, SPECIAL2_D, DESCRIPT, DESCRIPT2, and FGDLAQDATE. Fields were populated using a dbf containing all unique ATTRIBUTE values and definitions from the NWI Legend PDF: http://www.fws.gov/wetlands/Documents/NWI_Wetlands_and_Deepwater_Map_Code_Diagram.pdf 5 records were incorrectly attributed as either (X) or (H) in the SPECIAL1 field. These were changed to (x) and (h). Historically this data set is made available with polygons extending outside the extent of the state of Florida. The NWI wetlands team has begun clipping this dataset to the boundary of the 1:24,000 quads that intersect the 1:2 million state boundary. The dataset will be provided this way going forward. Please note that this is Version 1 of this NWI dataset. NWI is producing a new dataset denoted as Version 2 to better represent a more complete inventory of both surface waters and wetlands. For details on Version 2 please visit the USFWS NWI version 2 website: https://www.fws.gov/wetlands/Data/Wetlands-V2-Product-Summary.html Since the last update of this dataset USFWS has updated both the NWI Wetlands and Deepwater Map Code Diagram and NWI Water Regime Restriction Table. These changes have introduced new modifiers so expect codes that cannot be translated fully with the old charts. - Projected to FGDL Albers HARN - Upcased all records (except for SOIL, SPECIAL1 and SPECIAL2) - Renamed file from FL_Wetlands_V1 to nwip_may16 - DESCRIPT field calculated from SYSTEM_D - FGDLAQDATE added based on date downloaded from source.
