SoilGrids250m 2017-03 - Probability of occurrence of R horizon

Probability of occurrence of R horizon 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: probability.

基于全球土壤地面观测汇编数据预测得到的R层（R horizon）出现概率。该土壤图的精度评估可参阅Hengl等人（2017）的研究，DOI：10.1371/journal.pone.0169748。数据以GeoTIFF格式提供，采用内部压缩（co='COMPRESS=DEFLATE'）。测量单位：概率。
