Dataset Identification:
Resource Abstract:
- description: (<a href="http://maps.vcgi.vermont.gov/gisdata/metadata/WaterWetlands_NWIALL.htm" target="_blank">Link
to Metadata</a>) VCGI downloaded NWI quads from the US FWS web site and reprojected to VCS NAD83. NWI digital data files
are records of wetlands location and classification as developed by the U.S. Fish &amp; Wildlife Service. This dataset
is one of a series available in 7.5 minute by 7.5 minute blocks containing ground planimetric coordinates of wetlands point,
line, and polygon features and wetlands attributes. When completed, the series will provide coverage for all of the contiguous
United States, Hawaii, Alaska, and U.S. protectorates in the Pacific and Caribbean. Coverage includes both digital data and
hardcopy maps. The NWI maps do not show all wetlands since the maps are derived from aerial photointerpretation with varying
limitations due to scale, photo quality, inventory techniques, and other factors. Consequently, the maps tend to show wetlands
that are readily photointerpreted given consideration of photo and map scale. In general, the older NWI maps prepared from
1970s-era black and white photography (1:80,000 scale) tend to be very conservative, with many forested and drier-end emergent
wetlands (e.g., wet meadows) not mapped. Maps derived from color infrared photography tend to yield more accurate results
except when this photography was captured during a dry year, making wetland identification equally difficult. Proper use of
NWI maps therefore requires knowledge of the inherent limitations of this mapping. It is suggested that users also consult
other information to aid in wetland detection, such as U.S. Department of Agriculture soil survey reports and other wetland
maps that may have been produced by state and local governments, and not rely solely on NWI maps. See section on &quot;Completeness_Report&quot;
for more information. Also see an article in the National Wetlands Newsletter (March-April 1997; Vol. 19/2, pp. 5-12) entitled
