Geophysical Layers in European Geological Data Infrastructure (EGDI)

László Sőrés and Pedersen Mikael

(Submission #306)


On 14th of June, 2016 a first version of the European Geological Data Infrastructure EGDI has been launched. It provides access to Pan-European and national geological datasets and services from past and present projects run by the Geological Survey Organisations of Europe. Among a representative list of hot topics like groundwater, mineral resources, geo-energy, natural hazards etc., geophysics - as essential information source about underground structures

- is also present.

For demonstration purposes several geophysical datasets were restructured and made available in fully INSPIRE compliant form through view and download services. Selected datasets support use cases of high public interest and cross-border issues. Included datasets are seismic lines from Denmark, Vertical Electric Soundings from Hungary and Slovakia, and a resistivity map of NW Hungary created from raw sounding data by geophysical inversion.

Central WMS service is supported by flat table WFS on the data provider side with core INSPIRE attributes, and download links to GML features. INSPIRE downloads are served by MFGI by using online transformations from local SQL and XML database.

Apart from core feature attributes, technical details are also shared. It is done by exploiting the Observations and Measurements Sampling Feature model (observation metadata, process parameters). For the Danish seismic dataset, results from different processing stages can also be downloaded as PDF and SEG-Y files free of charge, thereby demonstrating the huge potential offered by the EGDI for a lot of possible applications if such services could be extended to other European countries in the future.

The user friendly portal environment of EGDI hides the complex background data infrastructure, but shows the flexibility of a distributed architecture, and demonstrates that data providers hosting INSPIRE compliant services can easily be integrated into Pan-European information systems like EGDI.
