Welcome to the CGI

CGI's mission is 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.

Current Working Groups

GeoSciML - a collaborative OGC-CGI standards working group developing a geological data transfer standard -

EarthResourceML - developing a data transfer standard for mineral resources and mining information -

Geoscience Terminology - developing multilingual vocabularies for geoscience and earth resources information -

Geoscience Information in Africa (GIRAF) – a collaborative network of African and global geoinformatics professionals working together to enable geoscience information to contribute to the environmental and economic prosperity of the people of Africa.

Join us at the 35th IGC in Cape Town

The 35th International Geological Congress is rapidly approaching in Cape Town, 27 August – 4 September.

The CGI is coordinating a symposium at the IGC on Geoscience Data & Information Systems, with over 40 presentations on a wide range of digital geological data management, data analysis, and data delivery topics.

The CGI is also offering a one day workshop on geoscience web services, entitled "Working with Interoperable Data" on 28 August. Registration costs only 800 ZAR (~50 USD). The workshop will explain CGI and OGC geoscience data standards, and demonstrate how to apply them in delivering and consuming WMS and WFS web services. The workshop will be presented by international experts in geoscience web services from CGI, OGC, OneGeology and INSPIRE.


Nominations for CGI Councillors for the 2016–2020 term are now open. If sufficient nominations are received, election of new councillors will occur in June, followed by confirmation of new councillors at the 35th International Geological Congress in Cape Town. Read the procedures for Council nominations.

The final version of the GeoSciML data transfer standard, version 4, has been released. XML schemas, UML documentation, and encoding examples are available at www.geosciml.org. The new version of GeoSciML covers the same breadth of data as did the previous version, but has been restructured to allow much simpler implementation by a wide range of user communities. The GeoSciML Standards Working Group is currently compiling an OGC modular specification document with the goal of ratification of GeoSciML v4.0 as a full OGC standard later in 2016.

A comprehensive mineral commodity vocabulary has been released by the EarthResourceML and Geoscience Terminology working groups. This vocabulary is the result of extensive collaboration between many national geological survey organisations. The vocabulary is also available through the CGI vocabulary service.

Join us at our LinkedIn group. The group provides a forum for CGI and LinkedIn members to connect with other geoscience professionals, post news of upcoming events, ask questions, and discuss your issues.
