- Abstract
- These data are a set of ARC/INFO coverages composed of polygonal and linear features. Coverages are based on official New York State Freshwater Wetlands Maps as described in Article 24-0301 of the Environmental Conservation Law. Coverages are not, however, a legal substitute for the official maps. Coverages are available on a county basis for all areas of New York State outside the Adirondack Park.
- Purpose
- To provide a faithful representation of official New York State regulatory freshwater wetlands maps for GIS resource analysis at scales equal to the 1 to 24,000 scale of original mapping or smaller scales (e.g., 1 to 100,000 scale).
- Supplemental Information
- Regulatory maps consist of mylar versions of New York State Department of Transportation 1 to 24,000 planimetric maps on which wetland boundaries and wetland identification codes are drawn. Planimetric maps are generally congruent with and have the same quad names as United States Geological Survey 7.5 minute topographic maps; a few of the Department of Transportation quads have extended borders. Regulatory wetland maps are prepared by NYSDEC and filed as required by the Freshwater Wetlands Act (Article 24 of the Environmental Conservation Law). Associated with the maps are Classification Sheets that list the Wetlands Identification Code, the municipality in which the wetland occurs and the regulatory class of each wetland. Preparation and filing dates vary by county. As amendments to the official maps occur, the coverages are updated so that the GIS information reflects the regulatory maps currently in use. Archive copies of county coverages with previous versions of the official maps are kept. An important feature of the official maps is that the lines indicate only "the approximate location of the actual boundaries of the wetlands" (ECL Section 24-0301(3)). For a final determination of the actual location of a wetland it is necessary to contact the NYSDEC office for the region in which the wetland occurs.

- 1. The documentation in the Entity and Attribute Overview section of the metadata, and the README referred to in that section, are integral parts of the Regulatory Freshwater Wetlands data. Failure to use the documentation in conjunction with the digital data constitutes a misuse of the data. 2. The digital freshwater wetlands data provided are not a legal substitute for the official Regulatory Freshwater Wetlands maps maintained by the Department of Environmental Conservation pursuant to Environmental Conservation Law Section 24-0301. Should a discrepancy exist between the digital data and the official maps, the official maps are the correct source of information. 3. The official regulatory freshwater wetlands maps may be amended from time to time; digital data obtained at an earlier date may therefore become obsolete. Digital data also may be altered independently of official map amendments in order to make improvements. These digital data cannot be relied on as a definitive statement of the location of freshwater wetlands. Wetland boundaries are subject to delineation by Department of Environmental Conservation regional personnel. 4. The borders of wetlands shown on both the official maps and the digital data are approximate at a scale of 1 to 24,000. Traditional cartographic or digital comparison of the wetland maps to mapped information that is collected and digitized at a larger scale than 1 to 24,000 is not cartographically acceptable and is subject to error. 5. It is inappropriate to make further distributions of the data, because digital wetlands data are not official regulatory maps and are subject to change. All requests for the digital wetlands data should be referred to the Cornell University Geospatial Information Repository https://cugir.library.cornell.edu/ or to the Habitat Inventory Unit, New York State Department of Environmental Conservation, 625 Broadway, 5th Floor, Albany, New York 12233-4754, telephone (518)402-8961.

- Wetland boundaries were delineated as "approximate" on 1 to 24,000 scale maps using a variety of methods, including aerial photographic interpretation, reference to published maps and field investigations. However, due to changes over time in the wetland resource, field verification of wetland boundaries is increasingly important. Digital wetland borders are derived from individual 1 to 24,000 quads, either by digitizing or by scanning followed by semi-automated raster to vector conversion. Quality assurance and quality control procedures included overlay of plot of digital boundaries on original source map with the condition for acceptance being no visible separation allowed between boundaries.

- WETID
- The wetland identification code of the wetland. When a wetland contains included
uplands, water bodies, tidal wetlands or other features, the polygon of the non-wetland
feature is coded with UPL, WAT, TID or OTH, respectively, in columns 8 - 10 of this field
and with the wetlands identification code of the surrounding wetland in the first 7
columns. Only the wetland identification code is a valid value for arcs. Wetlands with an
extended adjacent area have an asterisk (*) directly following the wetland identification
code as part of WETID. Found in PAT and AAT. (Unique ID)

- CLASS
- The regulatory class of the wetland as derived from the wetlands classification
sheets. Values are 1, 2, 3, and 4 for Class I, II, III, and IV wetlands, respectively. A
value of 0 is used for non-wetland features. A value of 9 is used for wetlands that do not
have a class. Only non-zero values for class are valid for arcs. Found in PAT and
AAT.

- REGU-ACRES
- The total regulatory size in acres of the wetland. This total includes all polygons
associated with the wetland such as included uplands or open water. This is the official
regulatory wetland size as specified in the Freshwater Wetlands Act (ECL Section
24-0107(1)(c)). If more than one wetland in the county has the same wetland ID, this item
will contain, incorrectly, the total area of all wetlands with the same wetland ID. Found
in PAT. (calculated value)
- Definition Source
- Calculated
- WETL-ACRES
- The total number of wetland acres in the wetland. This value is the sum of only the
wetland polygons belonging to a wetland ID; it excludes any included uplands or open water
bodies. This is an ecologically based total size, in contrast to the regulatory total
given in REGU-ACRES. Found in PAT. (calculated value)
- Definition Source
- Calculated
- REGION-ACRES
- The total number of regulated wetland acres as determined by DEC regional office
staff. This item has a value only if DEC regional staff have determined a value for the
size of the wetland that they consider more accurate than the value determined by the
geographic information system. Regional value may be determined from wetland maps at
scales larger than 1 to 24,000, from surveys, or from other means. This item may be coded
as 0 for some or all of the wetlands in a county coverage if regional staff have not
determined a value. Where REGION-ACRES exists, it should be considered the correct value
to be used in place of REGU-ACRES. Found in PAT. (calculated value)
- Definition Source
- Calculated
- POLY-ACRES
- The number of acres in the individual polygon. (calculated value)

- #_PARCELS
- The number of separate wetland polygons, or separate areas of wetland, making up
the regulated wetland. (calculated value)

- Entity and Attribute Overview
- Data are tiled as coverages showing wetlands of a single county. Coverages are named with the first four letters of the county's name followed by WET, e.g., ALBAWET. A link to the README file is found in Detail Citation for detailed usage notes. THESE NOTES ARE ESSENTIAL TO PROPER USE OF THE COVERAGES.
