In this concluding paper, we summarize the main advances coming forward from the joint conference of the International Union of Soil Sciences (IUSS) Working Groups (WG) “Digital Soil mapping” (DSM) and “GlobalSoilMap”. We outline the increased availability of data and covariates. Large efforts to rescue legacy data and to put them in a harmonized format are ongoing in many parts of the world. New countries are joining the GlobalSoilMap initiative. During the same time, significant progress have been made in the countries which were among the first to develop GlobalSoilMap products. We stress the recent trends in tools used for predictive mapping of soil properties. Some solutions were proposed to solve issues about data privacy. We give examples on how to move from DSM soil digital soil mapping assessment. Aligning our research with ongoing activities within the Global Soil Partnership of the FAO has been proven successful. A need was expressed to work on the uncertainty of indicators of prediction performances and to re-evaluate validation strategies. It is necessary to develop more intuitive metrics for uncertainty assessment for interpreting and evaluating soil maps. The main progresses, remaining issues and challenges and the way forward are summarized and we propose ambitious working plans and road-maps for the two WGs and stress their complementarities.

数字土壤测绘和GlobalSoilMap。主要进展和前进方向

在本结论文件中,我们总结了国际土壤科学联盟(IUSS)工作组(WG)“数字土壤制图”(DSM)和“ GlobalSoilMap ”联合会议的主要进展。我们概述了数据和协变量可用性的提高。在世界许多地方,人们正在进行着大量的工作来挽救遗留数据并将其以统一的格式保存。新国家正在加入GlobalSoilMap计划。同时,在最早开发GlobalSoilMap的国家中取得了重大进展。产品。我们强调用于土壤特性预测性测绘的工具的最新趋势。提出了一些解决方案来解决有关数据隐私的问题。我们举例说明如何从DSM土壤数字土壤测绘评估中脱颖而出。事实证明,使我们的研究与粮农组织全球土壤伙伴关系中正在进行的活动保持一致是成功的。有人表示需要就预测绩效指标的不确定性开展工作,并重新评估验证战略。有必要为不确定性评估开发更直观的度量,以解释和评估土壤图。总结了主要进展,尚存的问题和挑战以及前进的方向,我们为两个工作组提出了雄心勃勃的工作计划和路线图,并强调了它们的互补性。
