In a fast-changing world, environmental sustainability is a major challenge to be tackled to ensure the sustainable management of georesources for a safe and prosperous society. Addressing those issues will require a comprehensive understanding of the Earth's composition and its geological processes. With the help of new technologies and tools, the knowledge of geology is in constant evolution. However, the field's rapid growth creates major challenges; one of them is how to make sense of the massive amounts of data collected throughout the years.

Within the EPOS initiative, the Thematic Core Service (TCS) Geological Information and Modeling develops and consolidates the information and data infrastructures produced by the international community, such as the European Geological Surveys. Shared reference datasets on geological maps, boreholes (vertical shafts constructed for water, oil, or gas extraction), 3D and 4D geological models, mineral resources, geohazards, and groundwater are accessible to the community through the EPOS multidisciplinary platform. 

With virtual access to borehole data and catalogues of geological maps, users can retrieve consolidated information produced by research facilities. Besides, researchers will also enhance the sharing and publishing of their own data and content on the EPOS platform, thus increasing the visibility and standards of their work inside the geological community. 
 
By making data and services available and easily accessible through the EPOS infrastructure, the Geological Information and Modeling TCS will promote information interoperability with other TCSs. Members of the EPOS community will be able, for example, to complement their geological maps with existing seismological information in the EPOS' ICS data portal. Ultimately, this will facilitate interactions with different communities such as smart cities, local and regional governments, and foster dialogue with state agencies, local authorities, and industries.
