2 Outline What is Geoscientific spatial data (GSD)? GSD, EU policies and regulations What end-users for GSD? Beyond INSPIRE: issues related to GSD European Geoscientific Hamonisation/ Interoperability initiatives: examples Conclusions: challenges ahead

3 Geoscientific spatial data Geoscientific spatial data comprises a wealth of georeferenced spatial data sets describing geology, the specific properties of the components of the subsurface, their geometry, their relations; its resources and its threats.

4 Anthropic pressures - Pollution (soils, surface and groundwater, coastal areas) - Loss of resources (biotic resources, soils, water, minerals) - Change of erosion/ sedimentation regimes in coastal areas, coastal erosion Soil system Aquifer system Bedrock Towards a sustainable use of natural resources - the necessity for a 4-D approach in land-use planning and resource management: Infrastructures and technologies for resources knowledge and management, for sustainable resources gaining and use; for the reduction of pressures and the prevention of the impacts of threats Opportunities: - resources (soil, groundwater, energy - fossil and renewable-, minerals) - subsurface space - the memory of the Earth's past - heritage - landscapes Threats: - earthquakes - landslides - volcanism - tsunamis - rockfalls - ground motion - floods - swelling clays - underground cavities - radon and other gas emanations - deficiency or 2excess of specific elements

5 GSD EU policies and regulations (simplified examples) EU Sustainable Development Policy Soils Thematic Strategy Water Framework Directive and daughter Groundwater Directive Common Agricultural Policy Common Fisheries Policy Civil Protection Geology Groundwater quality Groundwater quantity Location of mineral resources Location of energy resources Geothermal heat flow Historical occurrences of geological hazards Erosion/ sedimentation (marine domain) Soils erosion

7 Beyond INSPIRE: issues related to GSD Harmonisation of geoscientific data can, depending on the specific data set, be a complex scientific undertaking requiring important resources. Harmonisation requires scientific expertise: in data harmonisation, analytical, processing and modelling processes; to define standard legends; to fully develop multi-lingual lingual specific thesauri It also requires: a clear demand/ mandate from end-users (including at the EU level!) for harmonised, interoperable metadata/ data; financing;...and a strong commitment by all concerned parties to support and adhere to the collective effort

8 The harmonisation process for geological maps A: non-harmonised geological data layer B: Stage 1 harmonisation after development of a common legend C: Stage 2 harmonisation after harmonisaion of the geological contacts Source: BRGM

9 European Geoscientific Harmonisation/ Interoperability initiatives: examples Development of multi-lingual lingual geoscientific thesauri: International Union of Geological Sciences; e-earthearth European on-shore geoscientific on-line metadata catalogue: GEIXS European off-shore geoscientific on-line metadata catalogue (seismic profiles boreholes, seafloor sediment samples): EU- SEASED 1:5,000,000 scale digital geological map of Europe Geochemical atlas of Europe European soil map at 1:1,500,000 scale eearth multilingual borehole geo-database (7 countries)

10 The EU-Seased Seased marine metadata catalogue: query window ( Metadata includes worldwide -sea-floor sediments; - seismic profiles; - bore-hole cores held at EU institutions. Over 330,000 sea-floor sediment samples are Referrenced. Supported by the EU FP5 programme and many partners. Website hosted by EuroGeoSurveys.

11 EU SeaSed: answer window

12 1:5,000,000 scale digital geological map of Europe (BGR) First harmonised geological map of Europe involved 48 geological surveys The database includes harmonised on-shore and off-shore lithological and geochronological data Contribution to global harmonisation of geological data (a GEOSS objective) and to the INSPIRE harmonisation process 2,500 object categories ~ 4 M Base layer for the synthetic representation of geology- related crossborder small-scale data (geological hazards, aquifers, geochemistry of surface formations and water)

13 Application: IUGS/CGI testbed to demonstrate the interoperability of geoscientific c data over the Channel, using OGC/ISO WMS and WFS protocols. The Internet application shows overplot of IGME 5000 geological map and boreholes from BRGM and BGS. Borehole data are served through h WFS servers as XMML files, and used in a web service producing drill-hole logs from both data sources.

14 National initiatives in GSD harmonisation/ interoperability: the British Geological Survey example UK harmonised all its digital attributed geological data at 1:625,000; 1:250,000 (offshore and onshore); 1:50,000 (onshore). It is in the process of producing a harmonised digital UK geological map at 1:10,000 scale It also developed an extensive harmonised geological hazards information system at 1:50,000 scale with harmonised data layers on swell and shrink clays, landslides, soluble rocks, compressible and collapsible deposits, running sand, radon..., part of a comprehensive information sytem on UK s subsurface with about 50 harmonised data layers Metadata is based on ISO Rock classifications are based on (where available) IUGS Standards

15 Further national intiatives Important other national initiatives are rapidly developing. The cases of the Czech Republic, France and the Netherlands will be presented in the publication to be submitted in September.

16 Regional initiatives Many European regions are rapidly developing INSPIRE relevant GIS European Regional Geological Surveys are important layers on a fast moving scene, and their coordination on/ preparation for the implementation of INSPIRE is progressing very well, as well as coordination with National Geological Surveys Example: the SGSS (Servizio Geodatabase Geologico, Sismico e dei Suoli) ) of the Region Emilia Romagna

18 Conclusions: INSPIRE supporting activities are developing in national and regional Geological Surveys. They would be significatively boosted by a clear European remit in their field of thematic expertise The specific issues of GSD harmonisation need to addressed through funded collective research work A end-user driven definition of demand for harmonised data is needed (who needs what harmonised data, at what scale? Who will/ can pay?) Linkages should be further strengthened between key stakeholders EC, the EEA, JRC
