THIS LAYER IS USED BY WETLAND STAFF FOR REFERENCE PUPOSES. This dataset represents wetlands included in Vermont's Significant Wetlands Inventory (WaterWetlands_VSWI). These often correspond with wetlands represented on USFWS National Wetland Inventory Maps (NWI), however, there may be differences in delineation or ommission/commission of certain wetlands. The Vermont Agency of Natural Resources determines which wetlands are included in the WaterWetlands_VSWI. Questions about wetland location and use should be referred to the ANR DEC Wetlands section, 244-6951. NWI maps were used by the State of Vermont Agency of Natural resources as a means of creating this data layer. Nearly two-thirds of the wetlands were hand digitized from RF 24000 scale NWI mylars. The remainder of the state was scanned from RF 24000 or RF 25000 scale mylars. These mylars were created by transfering wetland polygon boundaries from RF 62500 scale NWI mylars to RF 24000 scale base maps.

The initial dataset was scanned or digitized from "source" materials. The majority of the scanned data was based on RF 24000 scale mylars (redrafted from RF 62500 wetland maps). Digitized data was captured from RF 24000 and RF 25000 scale mylars (refer to Source Description for more info). The Vermont Agency of Natural Resources, VCGI, and other data developers created these initial data layers. Quality control for this dataset included the following; 1) edge-matching, 2) spatial fidelity, 3) attribute value correctness, 4) and topological integrity. The data layers (coverages) were appended into QUAD16 tiles. These were then "snapped" to the master QUAD16 tile boundary data layer. Edge-match errors greater that 50 meters were flagged for ANR review. Check plots were generated and used to identify the presence/absence of "regulatory" wetland polygons. Errors were flagged and corrected. Problems which could not be resolved by VCGI staff were forwarded to ANR for review. Check plots were also used to identify attribution problems. Errors were flagged and corrected. Problems which could not be resolved by VCGI staff were forwarded to ANR for review. Problems such as dangling nodes and labelerrors were identified and resolved. Dummy lines were added to some of the tiles due to the 5000 poly/arc PC Arc/Info problem. 1) Verified that the TYPE, SRCCODE, METHCODE, UPDACT, and LNTYPE were fully populated with appropriate values. 2) Verified that AAT and PAT file definitions were consistent between tiles. 3) Calculated AREA_AC and GISID attributes. 4) Verified and User-IDs were unique. The presence/absence/delineation of wetlands was not verified in the field. The intent of this data layer is to represent "regulatory" wetland recognized by the State of Vermont digitally. No attempt was made to improve the "correctness" of the "official" NWI maps. 1.200 map units Fuzzy Tolerance 0.00 map units Dangle This data layer is intended for planning and informational use, to alert the public to the presence of regulated wetlands. This data layer is not designed to be used as sole criteria in any decision making process. Questions about wetland location and use should be referred to the ANR DEC Wetlands section, 244-6951. This is a digital "representation" of Vermont's Significant Wetlands Inventor. The majority of the wetlands were digitized from USFWS NWI maps. NWI maps were developed by the NWI section of the US Fish and Wildlife Service. The USFWS NWI section staff used RF 80000 scale color infrared aerial photos (flown between 1975 and 1978), USGS topo sheets and other mapped and text data to interpret locations of wetlands. The areas were drawn onto topographic maps with a very wide pen; the pen width equals about 80 feet of ground distance on a RF 24000 scale map and about 200 feet on a RF 62500 scale map. The minimum wetland mapping unit is generally wetlands over 3 acres in size. VT ANR digitized from 24,000 scale NWI source maps were available. The remainder of the state was covered by 15' maps at RF 62,500 scale, which were redrafted from the original source materials onto 7.5' (RF 24,000) mylars and then scanned and vectorized. The data layer does not attempt to identify every wetland in the state. It identifies those defined by the State of Vermont as "regulatory". The wetlands in the WaterWetlands_VSWI coverage are mainly palustrine complexes (regulatory). A smaller subset of the data define riverine and lacustrine wetland complexes (regulatory). Single line streams are not included. The wetlands in this coverage are those regarded as regulatory by the VT Water Resources Board. They correspond to the outer boundaries of palustine areas mapped by the USFWS NWI section with the following exceptions (includes some riverine and lacustrine wetlands). In some tiles there were cases of mapping errors; the edges of polygons did not match from one map to another. In those cases the USFWS was contacted by the VT ANR DEC Wetlands Section. The corrections were sent back to the Wetlands section and then corrected in ANR/GIS. The paper copies of changes are on file in the ANR/GIS and the VT DEC Wetlands section. See Feature Accuracy for details on the accuracy of the source maps.This data layer is intended for planning and informational use, to alert the public to the presence of regulated wetlands. This data layer is not designed to be used as sole criteria in any decision making process. Questions about wetland location and use should be referred to the ANR DEC Wetlands section, 244-6951. The wetland boundaries are very approximate due to the methods used to generate the original maps. Errors of as much as 500 meters have been observed when clearly identifyable boundaries were plotted over RF 5000 scale orthophotos. Most boundaries are expected to be within several hundred meters of their true locations. However, not all wetlands appear on the NWI maps, and some non-wetland areas may appear as wetlands. Review of the NWI maps by the Wetlands Office of the VT Agency of Natural Resources has shown that only a very small percentage (estimated at 1-2%) of the wetlands on the NWI maps are not found on the ground; many of these have been filled in since the 1977 inventory. It is also estimated that there are about 25% more wetlands than appear on the NWI maps, most of these being below 3 acres in size (often closed-canopy wetlands or open water). Discrepancies have been noted between the original 1977 NWI maps and a more recent inventory along the Connecticut river.
