Los Angeles County soil patch metrics

Data summarizing unsealed soil surface delineations in the southern half of Los Angeles County, USA. Delineations were made by interpreting high-resolution aerial photographs in a random sample of 1-hectare hexagons. The data set includes the number of soil patches in each hexagon, the proportion of the hexagon that is soil, the size of the largest soil patch, the mean perimeter-area ratio for soil patches, interpolated ATSDR/CDC Social Vulnerability Index value for the hexagon location, and latitude/longitude coordinates.

本数据集概述了美国洛杉矶县南部非密封土壤地表的边界划分。边界划分通过解析随机选取的1公顷六边形网格中的高分辨率航空照片完成。数据集包含每个六边形内土壤块的数量、六边形土壤占比、最大土壤块的大小、土壤块的平均周长面积比、基于ATSDR/CDC社会脆弱性指数对六边形位置的插值值，以及经纬度坐标。
