WoSIS - Contributing institutions and experts

The development of WoSIS (World Soil Information Service) has been made possible thanks to the contributions and shared knowledge of a steadily growing number of data providers, including soil survey organisations, research institutes and individual experts. We gratefully acknowledge their contributions and look forward to new contributions!


Data providers

All data shared with us are first stored 'as is' in the ISRIC Data Repository. Subsequently, the profile data are quality-assessed and standardised using consistent WoSIS procedures. Ultimately, the licence specified by the various data providers will determine how ISRIC may share the standardised data with you. There are two options for this as described below:

A) The standardised data are made freely available to the international community (i.e. geo-locations may be shown; distributed via 'wosis-latest').

B) The standardised data themselves are NOT made available to the international community (e.g. geo-locations may not be shown). In this case, in accord with the licences specified by the data providers, the standardised point data may only be used by ISRIC (WDC-Soils) for producing SoilGrids and similar products (i.e. output as a result of advanced data processing); the latter 'derived-products' are made freely available to the international community. 

Data providers can define these terms in dataset-specific Letters of Agreement (Download template); the procedure for contributing profiles is described on a specific webpage.

The number of profiles for the two categories of licenses (in wosis_latest) can be queried using a dashboard (best viewed on desktop).

Density of point data with an A-type license (i.e., freely available)


Category A: Includes profile data standardised according to regular WoSIS workflow:  these data are made publicly available via 'wosis-latest' resp.  as 'snapshots'. 

In this category, the source data sets are broadly grouped by continent. For many source datasets, in particular compilations, the names of the contributing organisations/individuals may be found in the technical reports that accompany the various data sets.

a) New data contributions will be processed as soon as possible, and this generally in sequence of their receipt at ISRIC. We apologise if your submissions have not yet been listed here or if they have been cited wrongly. Similarly, other issues will be addressed as soon as we are informed about them (e.g. license-related).

b) As of June 2022, wosis_latest includes about 211,000 point data with A-type licenses, i.e. about 21,000 new data points vis a vis the preceding '2019 version' (see dashboard for quick overview). In addition to this, about 27,000 point data with type B-licenses were processed: as such, there are now 280,000 point data to support the next SoilGrids250m update.  The newly added profiles, about 48,000 in total (including both A and B license type), come mainly from Cuba (16.3k), Chile (13.6k), Spain (6.6k), Bolivia (4.4k), Costa Rica, Tunisia, Brazil, Zambia, United Kingdom, Switzerland, Indonesia, Cameroon, Mongolia (112), Namibia (106k) and Kazakhstan (40). Inherently, there are numerous gaps in the provided data depending on the purpose of the original surveys (as discussed here). 

c) The next WoSIS ingestion round will consider those profiles that were shared with ISRIC between January 2021 to May 2022, as well as new profiles shared in the framework of the EU Holisoils project, with special attention for Forest soils in Europe.

d) Several databases (e.g. WISE, AfSP and SOTER) were compiled in collaboration with numerous partners. In so far as possible, these have been listed/acknowledged in the technical reports that accompany these databases. Duplicate profiles arising in compilations are flagged in the WoSIS workflow.
