Sand content in % (kg / kg) at 6 standard depths (0, 10, 30, 60, 100 and 200 cm) at 250 m resolution

Sand content in % (kg / kg) 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, sand.wfraction = variable: sand weight fraction, usda.3a1a1a = 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,本数据集提供分辨率为250米的砂土含量数据，单位为百分比（kg/kg），涵盖6个标准深度：0、10、30、60、100及200厘米。数据基于全球土壤剖面与样本汇编的机器学习预测结果生成。详细处理步骤详见此处。本数据集未包含南极洲相关数据。如需访问并可视化相关地图，请访问OpenLandMap.org。若您发现地图存在漏洞、伪影或不一致之处，或有相关咨询，请通过以下渠道反馈： 1. 代码相关技术问题与咨询：https://gitlab.com/openlandmap/global-layers/issues 2. 一般性咨询与意见反馈：https://disqus.com/home/forums/landgis/ 所有内部文件均采用GDAL的"COMPRESS=DEFLATE"创建选项进行压缩。文件命名规则说明如下： - sol：主题为土壤（soil） - sand.wfraction：变量为砂土重量占比 - usda.3a1a1a：测定方法为实验室方法代码 - m：平均值（mean value） - 250m：空间分辨率/区块支撑尺度为250米 - b10..10cm：垂直参考基准为地表下10厘米深度 - 1950..2017：时间参考基准为1950-2017年时段 - v0.2：版本号为0.2
