USFWS NWI Region 5UnknownConnecticut Eelgrass Beds 2006 Polyvector digital datahttp://www.ct.gov/deepThis data layer was created by the USFWS National Wetlands Inventory, Region 5. Delineations of 2006 eelgrass beds were completed on the eastern Connecticut shoreline to the Rhode Island border. Fisher Island, Plum Island, and the northern shore of Long Island, New York were also included in this work. Spring 2006 True Color aerial photography was taken at a scale of 1:20,000 and used for detemining location and delineation of eelgrass beds. Extensive field work was conducted by the USFWS Region 5 Southern Coastal Zone program in September, October and November, with 290 field sites. The 2006 photography was scanned and geo-rectified using 2004 ADS 1/2 meter true color imagery.This dataset was developed for an ongoing eelgrass monitoring of the Long Island Sound.

The 2006, 1:20000 true color photography was scanned and geo-rectified to ADS 2004 true color 1/2 meter resolution imagery for Connecticut, and 1-ft resoluton true color 2004 New York State imagery. The 2002 eelgrass datalayer was used as a base, and polygonal data was added, subtracted or adjusted to reflect what was identified on the newer imagery. Field work was completed using a USFWS research vessel, and USFWS personnel. Two hundred and ninety sites were checked and documented. This information was converted to a point datalayer and used to adjust the original delineation.Dec '06 - Feb '07Herb BergquistUSFWSGIS Specialist/Biologist413-253-8621h_bergquist@fws.govnoneVectorG-polygon176Lambert Conformal ConicLambert Conformal Conic41.20000041.866667-72.75000040.833333999999.999996499999.999998coordinate pair0.0002500.000250survey feetNorth American Datum of 1983Geodetic Reference System 806378137.000000298.2572221.000000Explicit elevation coordinate included with horizontal coordinatesConnectcut Eelgrass Beds 2006 PolyOBJECTIDInternal feature number.ESRISequential unique whole numbers that are automatically generated.ShapeFeature geometry.ESRICoordinates defining the features.ACRESArea of polygonSITE_IDnumeric site #LOCATIONApproximate location based adjacent areasWATERSHEDWatershed numeric valueSIGNATURESsignatures of interpreted eelgrass bed1Patches, Dark Grn2Patches, Grn/Brn3Patches, Light Grn4Solid, Dark Grn5Solid, Dark Grn/Brn6Solid, Dark Grn/Blk7Solid, Grn/Brn8Solid, Light Grn9UndeterminedFIELD_06_VFIELD_02_VFeature geometry.ESRICoordinates defining the features.SHAPEFeature geometry.ESRICoordinates defining the features.BED_DENSITYSHAPE.areaSHAPE.lenConnectcut Eelgrass Beds 2006 PolyShapefile, Feature ClassArcGISZiphttp://www.ct.gov/deep20120119U.S. Fish & Wildlife ServiceHerb BergquistGIS Specialist/Biologistmailing and physical address
