Geological and Geophysical Databases
Led by: Czech Geological Survey (CGS)
Geological and geophysical data and access to existing relevant information is essential for the scientific research concerning the Earth sciences. The CGS-DRI (Data Research Infrastructure of the CGS) aims to provide effective access to geological, geophysical and related applied data using up-to-date technologies and both European and global standards. That is the main reason why CGS has joined the CzechGeo/EPOS RI in 2016. These valuable resources of data need to be consolidated and harmonized according to both European and global standards (INSPIRE directive, ISO standards, EGDI) and the accepted strategy of EPOS. Access to existing relevant information is essential for the scientific research, namely when aimed to the prediction and mitigation of landslides, subsidence, earthquakes, flooding and pollution. The data will be presented via web services and user-friendly web applications. The RI will then be sustainable and capable to provide thematic-relevant metadata, view and download services in accord with the relevant international standards and rules defined by EPOS, EGDI and INSPIRE. The open and free access principles will be applied whenever possible.
The main activities focused on the development of the CGS-DRI as a part of the CzechGeo/EPOS RI in 2016 were following:
1. Inventory of existing geological, geophysical and related applied data held by CGS has been performed. A large amount of already existing geological and geophysical data available in CGS in any form (structured and unstructured data, paper documents and primary documentation) has been evaluated of their relevance to EPOS, EGDI (Pan-European Geological Data Infrastructure), INSPIRE (Directive 2007/2/EC of the European Parliament and of the Council) and to support the scientific research within the infrastructure. Both primary, derived and overview data are processed. The prioritized data sets are made available to be subsequently analyzed, consolidated, harmonized, incorporated into the CGS-DRI, safely stored and made accessible.
2. The standardized procedures have been set to establish an effective access to already incorporated data resources. The CGS-DRI portal provides the one-point-access to a growing amount of relevant information. The data has been presented via web services using up-to-date standards and via user-friendly web applications.
3. The metadata catalogue has been amended and filled with the metadata to provide comprehensive information on existing data and information resources, compliant with the relevant ISO standards.
4. CGS is involved in the implementation of the INSPIRE Directive in the CR and has provided a lot of relevant information following the Annex II (Geology) specification: Metadata, View services, Download Services.
5. The Pan-European Geological Data Infrastructure (EGDI) aims to be a sustainable platform for results of past and future European geoscientific projects and provides the data and services to carry out pan-European research and support of policy making, risk mitigation, resource evaluation etc. The strategy is to develop interoperable, harmonized geoscientific information in multiple domains, based on the national knowledge and databases. It has an ambition to be the central pan-European geological data node as a part of the future European Geological Service. EGDI has been built as the basis for Information Platform in the GeoERA programme (ERA-Net on Applied Geoscience), Thematic Core Services on Geological Information and Modeling of EPOS and other data infrastructures (EMODnet, Copernicus and GEOSS). It is built on European and international standards (CGI, OGC) and serves as a live demonstration of implementation of INSPIRE principles.
To support this, the CGS has been a part of the core team, developing in 2016 the working prototype of EGDI. CGS developed the EGDI metadata catalogue to enable data to be discovered. CGS coordinated the metadata compilation and supervised the links between various data or services and the portal. CGS also contributes to the content of EGDI. The selected national data has been transformed to fulfill the EGDI-compliant principles and has been provided as the harmonized geological data to the portal as required at this stage of development.
