Fine sand fraction Base data soil mapping

This dataset is an area-wide multiband grid (resolution 10 x 10 m) composed of the modelled values for the fraction of fine sand (weight percentage) for 5 different soil-depth intervals (0-10, 10-30, 30-60, 60-100 and 100-150 cm) and the corresponding reliability for this modelled value per soil-depth interval. These data were calculated by means of digital soil mapping based on point observations of this soil property and area-covering predictor layers. The current dataset was calculated on the basis of the historical base data of the soil mapping (1945-1975). If a larger amount of recent soil data becomes available in the future, grid datasets will also be calculated on the basis of these recent soil data.本数据集为分辨率10×10米的全域多波段栅格，包含5个不同土壤深度区间（0-10、10-30、30-60、60-100及100-150厘米）的细砂含量（重量百分比）模拟值，以及各土壤深度区间对应模拟值的可靠性评估结果。该数据基于该土壤属性的点位观测数据与全域覆盖的预测因子图层，通过数字土壤制图（digital soil mapping）方法计算得到。本数据集依托1945-1975年土壤制图的历史基础数据生成。未来若可获取更多最新土壤观测数据，亦将基于该类最新数据生成对应栅格数据集。
