Parramore Island of the Virginia Coast Reserve Permanent Plot Coordinates: UTM (NAD83/GRS80) zone 18 2002

Coordinates of Parramore Island Permanent Vegetation Monitoring Plots. Coordinates are for plot center. Projection = UTM zone 18. Units = meters. Datum/Spheroid = NAD83/GRS80. These coordinates should be equivalent to those received by GPS using the WGS84 spheroid, and are in the form most useful for navigating in the field using handheld GPS. GPS locations are only approximate. See notes from the 1996 and 1992-93 surveys for additional descriptiions of the plot coordinates, including triangulation details from local landmarks.帕拉莫尔岛永久性植被监测样地坐标。坐标对应样地中心位置，投影采用通用横轴墨卡托（Universal Transverse Mercator，UTM）第18带，单位为米，基准面/椭球体为NAD83/GRS80。该坐标与采用WGS84椭球体的GPS设备所获取的坐标等效，且格式适配手持GPS开展野外导航作业。GPS定位结果仅为近似值。如需获取样地坐标的更多详细说明（包括基于本地地标的三角测量细节），请参阅1996年及1992-1993年调查的相关备注。
