SoilGrids250m 2017-03 - Coarse fragments volumetric

Coarse fragments volumetric in % at 7 standard depths predicted using the global compilation of soil ground observations. Accuracy assessement of the maps is availble in Hengl et at. (2017) DOI: 10.1371/journal.pone.0169748. Data provided as GeoTIFFs with internal compression (co='COMPRESS=DEFLATE'). Measurement units: v%.本数据集为基于全球土壤实地观测汇编数据预测得到的7个标准土层深度下的粗碎屑体积占比（%）。该空间分布图的精度评估详情可参见Hengl等（2017）的研究，DOI：10.1371/journal.pone.0169748。数据采用内部压缩格式的GeoTIFF文件提供，压缩参数为(co='COMPRESS=DEFLATE')。测量单位：体积百分比（v%）。
