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。本数据给出的坐标为样地中心点位坐标，采用UTM（通用横轴墨卡托投影）第18带投影坐标系，单位为米，基准面/参考椭球体为NAD83/GRS80。该坐标与采用WGS84（世界大地测量系统1984）参考椭球体的GPS采集坐标等效，其格式适配手持GPS开展野外导航作业。需注意，GPS点位仅为近似值。如需了解样地坐标的更多详细信息（包括基于本地地标进行三角测量的相关细节），请参阅1996年及1992-1993年调查的配套记录。
