Peterson Tionesta coordinates 20 random subsets mortality

This is an Excel spreadsheet, containing 20 randomly chosen subsets of tree coordinates from the Tionesta site. These 20 subsets consist of coordinates of 142 randomly chosen trees to simulate the 142 observed fallen trees at Tionesta; each subset is made up of a different random selection from among the 522 predisturbance trees. The first column lists the subset, and the second and third column give the x, y coordinates of a selected tree. The first column is integer data, and the second and third columns are decimal data. Coordinates are in m, from an arbitrary starting point in the southwest of the study site.

本数据集为一份Excel电子表格，包含从蒂奥内斯塔（Tionesta）研究区选取的20组随机树木坐标子集。该20个子集共计涵盖142株随机选取树木的坐标，用于模拟蒂奥内斯塔地区观测到的142株倒木；每个子集均从522株预干扰树木中独立随机选取得到。表格第一列标注子集编号，第二、第三列分别对应给出选定树木的x、y坐标。其中第一列为整数型数据，第二、第三列为十进制数值型数据。所有坐标单位为米（m），以研究区西南角作为任意基准原点。
