Abstract:
This data set is an ARC/INFO coverage 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.
Purpose:
Supplemental_Information:
Regulatory maps consist of mylar versions of New York State Department of Transportation 1:24,000 planimetric maps on which wetland borders 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) and implementing regulations. 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 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. Scale: 1:24000

Data_Quality_Information:
Logical_Consistency_Report:
The quads comprising a county are edge matched and map joined to form a county coverage. Quadrangle borders of wetlands that cross quads are dissolved away. Where contiguous wetlands on adjacent regulatory quad sheets do not match, arcs are added along the quad border between the wetland pieces on either side of the border so that a continuous polygon is formed. The same treatment is given to mismatches along county borders. Errors in the regulatory maps, such as mismatches along quad borders or duplicate wetlands identification codes are digitized faithfully. A list of errors is maintained by the Habitat Inventory Unit.
Completeness_Report:
This coverage is complete as of December 1994; coverages are updated shortly after official amendments.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Wetland borders are derived from individual 1:24,000 quads, either by digitizing or by scanning followed by semi-automated raster to vector conversion.
Quantitative_Horizontal_Positional_Accuracy_Assessment:
Horizontal_Positional_Accuracy_Value: +/- 15 meters
Horizontal_Positional_Accuracy_Explanation:
Based on the scale of the source map documents and the placement of Regulatory Freshwater Wetlands by "best-visual-fit" for detail sheets, the horizontal positional accuracy is estimated to be within the range of +/- 15 meters.
