Parramore Island of the Virginia Coast Reserve Permanent Plot Baseline Data : Plot Coordinates 1992-1993

This contains coordinates (UTM zone 18N, NAD27) for permanent vegetation plots on Parramore Island. Plots were established using a uniform random number generator to generate random coordinates. One hundred of the random points that fell on the upland portion of Parramore Island (based on the McCaffrey vegetation maps) were selected as plot centers.

本数据集包含帕拉莫尔岛（Parramore Island）永久植被样地的坐标信息，其坐标系采用通用横轴墨卡托投影18N带（UTM zone 18N），基准面为北美大地基准27（NAD27）。样地布设时，通过均匀随机数生成器（uniform random number generator）生成随机坐标，随后基于麦卡弗里植被图（McCaffrey vegetation maps）筛选出位于帕拉莫尔岛高地范围内的100个随机点，将其作为样地中心。
