PDF Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 2; ESRI ArcCatalog 9.2.4.1420 ESRI point geometry. All point features are unique. There are no duplicate points. Each plot is represented by one point. All points fall within the mapped polygons. Following methodology developed by the Nature Conservancy in conjunction with the USGS/NPS Vegetation Mapping Program, an attempt was made to sample each vegetation association at least three times. Within sampled polygons, locations of plots suitable for vegetation description were selected based on the ability to collect information in the area that best represented the existing vegetation. The location of each plot was recorded with a Trimble Geoexplorer 2 global positioning system (GPS) unit in Connecticut State Plane Coordinates, with the datum set to North America 1983 (Conus). These data were re-projected to Universal Trans-Mercator (UTM) coordinate system for the final map. 2005 Vector Entity point 29 Universal Transverse Mercator 18 0.999600 -75.000000 0.000000 500000.000000 0.000000 coordinate pair 0.000001 0.000001 meters North American Datum of 1983 Geodetic Reference System 80 6378137.000000 298.257222 Attributes of wefa_veg_plots_2004_utm Shapefile attribute table State Geological and Natural History Survey of Connecticut, Department of Environmental Protection FID Internal feature number.
