XIth International Congress for Mathematical Geology - September 3-8, 2006 – Liège, Belgium > 3 1. INSPIRE Directive (1/3) INSPIRE: INfrastructure for SPatial InfoRmation in Europe INSPIRE aims at making available relevant, harmonised and quality geographic information for the purpose of formulation, implementation, monitoring and evaluation of Community policy-making. 1.Data should be collected once and maintained at the level where this can be done most effectively 2.It should be possible to combine seamlessly spatial data from different sources and share it between many users and applications 3.Spatial data should be collected at one level of government and shared between all levels 4.Spatial data needed for good governance should be available on conditions that are not restricting its extensive use 5.It should be easy to discover which spatial data is available, to evaluate its fitness for purpose and to know which conditions apply for its use INSPIRE Principles:

XIth International Congress for Mathematical Geology - September 3-8, 2006 – Liège, Belgium > 4 1 – INSPIRE - Spatial data needed are grouped into 3 annexes (2/3) Annex I Coordinate reference systems Geographical grid systems Geographical names Administrative units Transport networks Hydrography Protected sites Annex II Identifiers of Properties Elevation (including terrestrial elevation, bathymetry and coastline) Geology Land cover Cadastral parcels Ortho-imagery

XIth International Congress for Mathematical Geology - September 3-8, 2006 – Liège, Belgium > INSPIRE - Annexes (3/3) Annex III Statistical units Buildings Soil Land use Human health and safety Government service and environmental monitoring facilities Production and industrial facilities Agricultural and aquaculture facilities Population distribution - demography Area management/restriction/ regulation zones & reporting units Natural risk zones Atmospheric conditions Meteorological spatial features Sea regions Bio-geographical regions Habitats and biotopes Species distribution Oceanic spatial features

XIth International Congress for Mathematical Geology - September 3-8, 2006 – Liège, Belgium > GeoScienceML and Testbed (1/5) A Data Model Collaboration working group set up under the auspices of the CGI (Commission for the Management and Application of Geoscience Information) of IUGS (the International Union of Geological Sciences). Two task groups: 1. Conceptual Model / Interchange Development of a Geoscience conceptual model of geoscientific data and a related interchange format, with a priority : a focus on geological maps and boreholes 2. Testbed Implementing the agreed subset of the conceptual model as a working system, demonstrating the interchange of data between more than one server and client and examples of derived services on data => See detailed presentation of GeoScienceML and a testbed demo this afternoon

XIth International Congress for Mathematical Geology - September 3-8, 2006 – Liège, Belgium > 12 Data harmonisation and Interoperability > Data harmonisation within the ESDI means that all countries use a common set of coordinate reference systems, data model, classification system, etc. > Interoperability within the ESDI means that each country maintains their own infrastructure, but adopts a framework that enables existing datasets to be linked up from one country to another (e.g. via transformation or translation > In case of heterogeneous data sources, interoperability requires wrapping data sources into services that conform to standards. > The output of these services is what to be harmonized, not their inputs (database schemas). 3 - Contribution of GeoSciML / Testbed (2/5)

XIth International Congress for Mathematical Geology - September 3-8, 2006 – Liège, Belgium > Conclusion The work done in the CGI working group on GeoSciML is very relevant for the data harmonisation process in INSPIRE for Geological theme. The testbed demonstrates the use of services based on standard (WMS and WFS) to display and access geological data; services that are required by the INSPIRE directive (view and download).
