ISRIC - World Soil Information (WDC-Soils) has a mission to serve the international community as custodian of global soil data and information, and to increase awareness and understanding of soils in major global issues. With partners we have implemented a server database based on PostgreSQL, known as WoSIS (World Soil Information Service). The aims are to safeguard and subsequently share soil data upon their standardization and harmonization. The data come from disparate sources; conditions for use are stored in WoSIS together with the full data lineage to ensure that data providers are duly acknowledged. In accord with these conditions (licenses), the submitted data is gradually standardized and harmonized, ultimately to make them “comparable as if assessed by a single given (reference) method.” So far, we have focused on point (profile) data, limiting ourselves to the selection of soil analytical and physical properties listed in the GlobalSoilMap (2013) specifications. A wider range of quality-assessed soil data (point, polygon, and grid) will be considered in the future. The present complement of standardized soil profile data is freely accessible at: http://www.isric.org/content/wosis-distribution-set.
