Coarse fragments % (volumetric) at 6 standard depths (0, 10, 30, 60, 100 and 200 cm) at 250 m resolution

Coarse fragments % (volumetric) at 6 standard depths (0, 10, 30, 60, 100 and 200 cm) at 250 m resolution. Based on machine learning predictions from global compilation of soil profiles and samples. Processing steps are described in detail <strong>here</strong>. Antarctica is not included. To access and visualize maps use: OpenLandMap.org If you discover a bug, artifact or inconsistency in the maps, or if you have a question please use some of the following channels: Technical issues and questions about the code: https://gitlab.com/openlandmap/global-layers/issues General questions and comments: https://disqus.com/home/forums/landgis/ All files internally compressed using "COMPRESS=DEFLATE" creation option in GDAL. File naming convention: sol = theme: soil, coarsefrag.vfraction = variable: coarse fragments volumetric fraction, usda.3b1 = determination method: laboratory method code, m = mean value, 250m = spatial resolution / block support: 250 m, b10..10cm = vertical reference: 10 cm depth below surface, 1950..2017 = time reference: period 1950-2017, v0.2 = version number: 0.2,本数据集提供250米分辨率下，6个标准深度（0、10、30、60、100、200厘米）的粗碎屑体积占比（%）数据。数据集基于全球土壤剖面与样本汇编的机器学习预测结果构建。详细处理步骤详见此处。本数据集不含南极洲区域数据。 如需访问并可视化该数据集的地图，请访问OpenLandMap.org。若您发现地图存在漏洞、伪影或不一致问题，或有相关疑问，请通过以下渠道反馈：代码相关技术问题与咨询：https://gitlab.com/openlandmap/global-layers/issues；一般性疑问与意见反馈：https://disqus.com/home/forums/landgis/。 所有文件均采用GDAL的"COMPRESS=DEFLATE"创建选项进行内部压缩。 文件命名规则如下：sol代表主题（theme）：土壤（soil）；coarsefrag.vfraction代表变量（variable）：粗碎屑体积占比（coarse fragments volumetric fraction）；usda.3b1代表测定方法（determination method）：实验室方法代码；m代表平均值（mean value）；250m代表空间分辨率/栅格支撑尺度（spatial resolution / block support）：250米；b10..10cm代表垂直参考基准（vertical reference）：地表以下10厘米深度；1950..2017代表时间参考（time reference）：1950-2017年时段；v0.2代表版本号（version number）：0.2。
