About Us

CGI’s mission

To foster the interoperability and exchange of geoscience information, by active community leadership, collaboration, education, and the development and promotion of geoscience information standards and best practice.

CGI’s vision

  • that geoscience information can be exchanged, understood, and used without limitation,
  • that geoscience information can be readily integrated with standards-based information from other knowledge domains,
  • that geoscience information is semantically rich and structured to enable seamless interaction in all environments,
  • that global education about the management, modelling, exchange, and use of geoscience information enables its best possible application,
  • for the benefit of all society.

Our Partners


OneGeology’s aim is to create dynamic digital geological map data for the world. It is an international initiative of the geological surveys of the world who are working together to achieve an ambitious and exciting venture. The OneGeology organisation endorses and uses the GeoSciML data transfer standard and has worked closely with CGI in providing a platform for the use and promotion of CGI data standards.

Open Geospatial Consortium (OGC)

CGI is a strong supporter of the open standards framework established by OGC. CGI and OGC cooperate under a Memorandum of Understanding signed in 2013 under which the future development of GeoSciML will be undertaken in an OGC Standards Working Group (SWG).

Infrastructure for Spatial information in the European Community (INSPIRE)

The INSPIRE directive have chosen CGI standards - GeoSciML and EarthResourceML - as the mandated European data transfer standards for geological and mineral resources information. The technical working groups of the INSPIRE directive have cooperated with CGI in the development of data standards and geoscience vocabularies.

US Geoscience Information Network (USGIN)

USGIN is an operational federated information-sharing framework that helps individuals and agencies develop scalable, interoperable, web-accessible data-sharing networks. USGIN participates in the development of standards, practices, and protocols through ESIP, CGI and the OGC, and deploys systems using these to exchange geoscientific data over the Internet using free-and-open-source software.

Election of Council 2020 - 2024

The Council was elected in 2020 for the term 2020-2024. The newly elected Council members are widely distributed across many of the continents. The planned annual face to face Council meeting in Delhi, India at the 36th IGC was canceled due to the COVID-19 pandemic.

CGI council elections

Nominations for CGI Council for 2020–24 are open. Any CGI member can nominate to serve on the council to help organise CGI’s standards programme and the outreach activities of the CGI.

CGI Award for Young Earth Scientists at the 36th IGC

CGI sponsors an award to assist early career scientists to present at conferences such as the IGC

36th International Geological Congress

Abstracts are invited to the special symposium Advances in geoscience data sharing and processing (Theme 45.10) at the 36th International Geological Congress (IGC). The symposium will highlight new techniques, standards, and algorithms for managing, delivering, visualising and analysing geoscience data both globally and regionally, including ‘big’ data.

Working Groups


DDE Standards Task Group

A collaborative task group implementing geoscience information standards for IUGS’s flagship Deep-time Digital Earth Project


A CGI working group developing and publishing data standards for mineral resources and mining information


A collaborative OGC-CGI working group for the GeoSciML geological data standard

OGC-CGI Geoscience Domain Working Group

connecting people to develop, improve and promote technologies for geoscience data description and sharing

Geoscience Terminology Working Group (GTWG)

A CGI working group developing and publishing multi-lingual geoscience vocabularies


Although the CGI does not have any formal working group concerned with geoscience metadata it was felt that it could help geoscience organisations develop their metadata implementations by providing a forum for posting work and discussions.


Pan-African geoscience information knowledge network of Geological Surveys, universities and companies

Regional Working Groups

The CGI council recognises the potential need to institute working groups that will address the specialised technical or scientific needs of regions defined by culture, geography or politics and encourages the establishment of CGI Regional Working Groups (RWG).

Multilingual Thesaurus Working Group

The mission of the MLTWG was to enable the global exchange of geoscience information with the help of a common multilingual core vocabulary by developing and expanding the Multilingual Thesaurus of Geosciences.

Interoperability Working Group

The Interoperability Working Group was formed to develop data standards to facilitate the query and exchange of geological information between data providers for environmental, scientific, legal and social purposes.

DDE Geoscience Information Metadata Standard

This standard defines the information content and XML serialization for metadata descriptions of geoscience information resources supporting the DDE program. It provides information about the identification, quality,contents, spatial reference, lineage, and distribution of the data. This standard applies to the description ofgeoscience data resources including a variety of geoscientific disciplinary spatial and non-spatial data, toensure they are Findable, Accessible and with sufficient documentation to make them Reusable. The scope of DDE Geosciences Information metadata is defined to include the resource types listed in the resourceType codelist. See the ResourceTypeCode «CodeList» in Annex A. Conformance with this standard will ensurethat DDE metadata are i nteroperable, facilitating metadata searching, h arvesting and sharing.
