The major share of raw materials needed to sustain our present lifestyle and even more importantly, required for the crucial green transition, are sourced outside Europe. The European Commission aims to enhance Europe's resilience and strengthen domestic sourcing. Although Europe has a long tradition of mining and extractive activities, it is acknowledged that there are several challenges to achieve European sourcing of certain raw materials such as the critical raw materials. A basic prerequisite to enable access to domestic raw materials is information on raw material occurrences, current and past mining activities, resources and reserves. The Geological Survey Organisations (GSOs) of Europe play a key role in generating, compiling, gathering, and storing the most up to date information as well as long-term data series on raw materials at national and regional levels. Over the last decade, the GSOs have joined forces and taken essential steps to harmonise and share data on raw materials. The results of this cooperation are illustrated as interactive maps on the European Geological Data Infrastructure (EGDI). This paper describes the data compiled in cooperation between the GSOs, and analyses the strengths and weaknesses of as well as opportunities for and threats towards the data.
EuroGeoSurveys (EGS) is a not-for-profit organization representing 37 national geological surveys and some regional surveys; it has an overall workforce of several thousand experts. EGS members provide official, interoperable, homogeneous, reliable, INSPIRE (infrastructure for spatial information in the European Community)-compliant public data on the subsurface for the benefit of society in terms of circular economy development, sustainable management of the subsurface resources, understanding and combatting climate change and the development of infrastructures and mitigation of geology-related natural hazards. The EGS is committed to establishing a geological service for Europe based on three pillars: (1) joint research with impact on EU policy level, which is being implemented through the GeoERA programme (Establishing the European Geological Surveys Research Area to deliver a Geological Service for Europe); (2) harmonizing and sharing pan-European geological data, through the European Geological Data Infrastructure (EGDI); and (3) sharing knowledge, capacities and infrastructure, through the pan-African support to the EGS-Organization of African Geological Surveys (OAGS) Partnership (PanAfGeo project). The EGS will continue to support the EU in its transition to a low-carbon, climate-neutral, resource-efficient, socially and environmentally resilient economy, in full compliance with the United Nations 2030 Agenda and the 17 Sustainable Development Goals.
In recent years the Geological Survey of Denmark and Greenland (GEUS) has, for a variety of reasons, worked intensively on implementing Internet technologies. The most important aim has been to provide public and private companies with access to many of the geological databases and maps at the Survey, thus substantially increasing the value of the geological data. In this way GEUS is implementing the intentions of the United Nations Aarhus-convention in respect of access to information, public participation in decision-making and access to justice in environmental matters (UNEC 1998). Another important objective has been to improve the procedures that deal with data input, registration and quality control of the large amounts of data that GEUS receives from regional authorities, private drilling companies and advisers, as well as that acquired by the activities of its own geological staff. This complies with the Danish Government’s initiatives for making the public sector more efficient through digital data management.
In the following we describe the result of the Titan Project, an interactive web application (Titan) developed at the Geological Survey of Denmark and Greenland (GEUS) together with DuPont Titanium Technologies. The main aim of Titan is to make computer-controlled scanning electron microscopy (CCSEM) data, generated at GEUS, available via the internet. In brief, CCSEM is a method automatically to detect particles with a scanning electron microscope (SEM), and based on computer-controlled imagery to measure the chemistry and grain morphology of each particle in a given sample (Knudsen et al. 2005; Bernstein et al. 2008); Keulen et al. 2008. Titan makes data available on-line so that the user can interact with the data sets and analyse them using a web browser. In addition to CCSEM data, Titan contains a global database of titanium deposits and various reports. The web application is customised, such that the functionality and amount of data available for a given user depend on the privileges of that user.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
