Use Constraints: 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 <http://cugir.mannlib.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.

Additional information on resource:

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 offical 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. For a sample of what a county coverage looks like, see <http://cugir.mannlib.cornell.edu/SAMPLES/001fwa.gif> (Note: Example is for Albany County).

Coverage description

Type of coverage content 

Cell value attribute description:  

Band

descriptor 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.

sequence Identifier

name WETID

Band

descriptor 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.

sequence Identifier

name CLASS

Band

descriptor 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.

sequence Identifier

name REGU-ACRES

Band

descriptor 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.

sequence Identifier

name WETL-ACRES

Band

descriptor 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.

sequence Identifier

name REGION-ACRES

Band

descriptor The number of acres in the individual polygon.

sequence Identifier

name POLY-ACRES

Band

descriptor The number of separate wetland polygons, or separate areas of wetland, making up the regulated wetland.
