'International' soil standards
Providing information on the soils of the world is an enormous task and continuing challenge for ISRIC — World Soil information. ISRIC collects, standardises/harmonises and publishes global soil geographic information, whereas many national, regional, local and NGO organizations provide soil information specific to their area and according to their procedures and standards. This page is to evolve towards a comprehensive catalogue of ‘international’ standards in the soil domain.
You are welcome to suggest other sources for consideration on this evolving page using the e-mail button at the bottom of this page.

Digital soil mapping
- Global SoilMap specifications: Sets out the specifications for GlobalSoilMap project data products (Tiers 1 to 4); GlobalSoilMap will include prediction of soil properties at fine spatial resolution (~100 m). The Specifications do not prescribe how the products must be made; only what they need to conform to in order to permit global collation and presentation of consistent standardized data. Click here
- Soil Grids, global gridded soil information derived from digital soil mapping. Click here and here.
Digital Soil Mapping (DSM) is the creation and the population of a geographically referenced soil database, generated at a given resolution by using field and laboratory observation methods coupled with environmental data through quantitative relationships. IUSS DSW Working Group, click here.
Spatial data specifications
- INSPIRE data specification for the spatial data theme soil. The INSPIRE Directive aims to create a European Union spatial data infrastructure for the purposes of EU environmental policies and policies or activities which may have an impact on the environment. This European Spatial Data Infrastructure will enable the sharing of environmental spatial information among public sector organisations, facilitate public access to spatial information across Europe and assist in policy-making across boundaries.

Soil data interoperability
- OGC Soil data interoperability experiment (IE): This IE evaluated existing models for soil data exchange and proposed a common core model, including a GML/XML schema, which was tested through the deployment of OGC web services and demonstration clients. IE time constraints and limited participant resources precluded extensive modelling activities. However, the resulting model should form the core of a more comprehensive model to be developed by an OGC Soil Data Standards Working Group in collaboration with other parties, including the IUSS working group on Soil Information Standards (WGSIS), the Soil Data working group of GODAN, and Pillar 5 of the Global Soil Partnership.
- Soil Data Working Group, GODAN, aims to ensure that a significant stakeholder group will be involved in the current development process (GSP, ISO, OGC), so that a truly global exchange standard can be developed and agreed. Click here.

- ISO 19168-1:2020: Geographic information — Geospatial API for features — Part 1: Core. This document specifies the behaviour of Web APIs that provide access to features in a dataset in a manner independent of the underlying data store. This document defines discovery and query operations. Click here
- ISO 19115-1:2014: Geographic information – Metadata. An internationally-adopted schema for describing geographic information and services. It provides information about the identification, the extent, the quality, the spatial and temporal schema, spatial reference, and distribution of digital geographic data. Click here
- ISO 19119:2016: Geographic information services. Defines requirements for how platform neutral and platform specific specification of services shall be created, in order to allow for one service to be specified independently of one or more underlying distributed computing platforms. Click here
- ISO/TS 19139-1:2019: Defines XML-based encoding rules for conceptual schemas specifying types that describe geographic resources. The encoding rules support the UML profile as used in the UML models commonly used in the standards developed by ISO/TC 211. The encoding rules use XML schema for the output data structure schema.
