Africa Soil Profiles Database, version 1.0

ISRIC World Soil Information is compiling legacy soil profile data of Sub Saharan Africa, as a project activity of the AfSIS project (Globally integrated Africa Soil Information Service). http://africasoils.net/services/data/soil-databases/

Africa Soil Profiles database, version. 1.0 (April 2012) identifies less than 15700 unique soil profiles inventoried from a wide variety of data sources. From the less than 14600 profiles that are geo-referenced, soil layer attribute data are available for less than 12500 and soil analytical data for less than 10000 profiles. The database includes, but is not limited, to the soil attributes specified by GlobalSoilMap.net. Soil attribute values are standardized according to e-SOTER conventions and validated according to routine rules. Odd values are flagged. The degree of validation, and associated reliability of the data, varies because reference soil profile data, that are previously and thoroughly validated, are compiled together with non-reference soil profile data of lesser inherent representativeness.

Updated milestone versions of the dataset have been posted online and made available to the project serving as input to the soil property maps generated by AfSIS. The continuously growing dataset will also be made available through the World Soil Information Service upon continuation of the project activity. The version is released here is version 1.0., the latest version is 1.1.

ISRIC世界土壤信息中心（ISRIC World Soil Information）作为非洲土壤信息服务（AfSIS, Globally integrated Africa Soil Information Service）项目的一项活动，正在整理撒哈拉以南非洲的历史留存土壤剖面数据。相关数据源可访问：http://africasoils.net/services/data/soil-databases/

非洲土壤剖面数据库（Africa Soil Profiles database）1.0版（2012年4月）收录了从各类数据源中获取的不足15700个独特土壤剖面。其中已完成地理配准的剖面不足14600个，具备土层属性数据的剖面不足12500个，具备土壤分析数据的剖面不足10000个。该数据库涵盖但不限于GlobalSoilMap.net所规定的土壤属性。土壤属性值依据e-SOTER公约完成标准化，并按照常规验证规则开展校验，异常值均已标记。由于将此前经过全面验证的参考土壤剖面数据与固有代表性稍逊的非参考土壤剖面数据一同收录，因此数据的验证程度与关联可靠性存在差异。

该数据集的更新里程碑版本已在线发布，可供该项目作为AfSIS生成土壤属性图的输入数据使用。随着本项目活动的持续推进，这个持续扩容的数据集也将通过世界土壤信息服务（World Soil Information Service）对外共享。本次在此发布的版本为1.0版，当前最新版本为1.1版。
