Legacy soil data have been produced over 70 years in nearly all countries of the world. Unfortunately, data, information and knowledge are still currently fragmented and at risk of getting lost if they remain in a paper format. To process this legacy data into consistent, spatially explicit and continuous global soil information, data are being rescued and compiled into databases. Thousands of soil survey reports and maps have been scanned and made available online. The soil profile data reported by these data sources have been captured and compiled into databases. The total number of soil profiles rescued in the selected countries is about 800,000. Currently, data for 117, 000 profiles are compiled and harmonized according to GlobalSoilMap specifications in a world level database (WoSIS). The results presented at the country level are likely to be an underestimate. The majority of soil data is still not rescued and this effort should be pursued. The data have been used to produce soil property maps. We discuss the pro and cons of top-down and bottom-up approaches to produce such maps and we stress their complementarity. We give examples of success stories. The first global soil property maps using rescued data were produced by a top-down approach and were released at a limited resolution of 1km in 2014, followed by an update at a resolution of 250m in 2017. By the end of 2020, we aim to deliver the first worldwide product that fully meets the GlobalSoilMap specifications.
在世界几乎所有国家，传统土壤数据的产生已有70多年历史。遗憾的是，目前数据、信息和知识仍处于碎片化状态，若仍以纸质形式保存，有丢失风险。为将这些传统数据处理成一致、空间明确且连续的全球土壤信息，数据正被抢救并汇编到数据库中。数千份土壤调查报告和地图已被扫描并在线提供。这些数据源报告的土壤剖面数据已被采集并汇编到数据库中。在选定国家抢救的土壤剖面总数约为80万。目前，根据全球土壤图规范，在一个世界层面数据库（WoSIS）中已汇编并协调了11.7万个剖面的数据。在国家层面呈现的结果可能被低估了。大部分土壤数据仍未被抢救，应继续开展这项工作。这些数据已被用于制作土壤属性图。我们讨论了自上而下和自下而上方法制作此类地图的利弊，并强调了它们的互补性。我们给出了成功案例。利用抢救数据制作的首批全球土壤属性图是通过自上而下的方法制作的，于2014年以1公里的有限分辨率发布，随后在2017年以250米的分辨率进行了更新。到2020年底，我们的目标是提供首个完全符合全球土壤图规范的全球产品。
