  1. Concept for an Integrated Web Solution / an Infrastructure for Geostatistics(Subproject 3) European Forum for GeoStatistics 2008 in Bled

  2. Vision of the integrated geostat web application • Information can be easily discovered no matter the source • The quality and usefulness of data can be assessed • All information can be combined or transformation operations exist • There are no barriers to access data • Distributed web services allow all kinds of operations • …

  3. Existing Framework • INSPIRE • Kopernikus (GMES) • SEIS • ESS

  4. INSPIRE • Legal support • Institutional support at European level • Institutional support by Member States • Financial support • A large user community • Methodologies, use cases, etc. • EU Geoportal still in experimental stage • 8 years of work and many more to come

  5. Kopernikus (GMES) • Legal support • Political support • Institutional support at European level • Institutional support by Member States • Financial support • Still missing: IT tools, applications beyond prototype status

  6. SEIS • Political support • Institutional support at European level • Financial support • Still missing: IT tools, methodologies, use cases, etc.

  7. SEIS – Environmental Data Centres • 2008 Communication of SEIS • First implementation in the form of environmental data centres (10, owned by EUROSTAT, JRC, EEA) • Currently in the user requirements phase • First attempts to build a common system architecture date from 2006 • Next deadline for an architecture proposal end of 2008 • Most advanced example of a data centre is WISE

  8. WISE • Portal to spatial and thematic data on water • Centred on River basin districts as reporting units (not exactly small scale statistics) • Currently only access to spatial data and data on the state of river bodies. • Limited access to documents • Analysis scenarios still to come • Architecture very much based on a spatial SDI

  9. European Statistical System - Eurostat • Long tradition in providing official statistics • Legal basis • Institutional support • Isolated Application to show statistical data (Tables Graphs Maps) • Technologies for data exchange between e.g. Eurostat and NSI (in the future SDMX)

  10. Quick start on SDMX • “Statistical Data and Metadata Exchange” • Exchanging and sharing of statistical data and metadata among international organisations and their member states • Applicable to all domains of statistics • Follows the publish, find and bind pattern

  11. Benefits from SDMX standards • XML based and therefore neutral in terms of underlying technologies • Avoids duplication of development, saves development costs and proliferation of “proprietary” developments • Pools the expertise and resources working on data and metadata issues in sponsoring organisations

  12. International Organisations with SDMX Implementations • Eurostat’s SDMX Open Data Interchange • Eurostat Census • IMF’s Metadata Repositories • UN Millennium Development Goals indicators • FAO Country Stats • ILO Labor Statistics • UNESCO-Eurostat-OECD Education Statistics … growing fast

  13. Domain-Specific SDMX Implementations in ESS

  14. Key SDMX Products • technical standards • standard format for data and reference metadata • architecture for data exchange • SDMX registry • guidelines • E.g. how to construct metadata descriptions • freely available implementation tools • SDMX Registry • SDMX Metadata Converter

  15. Example - the Census Hub project • The Census Hub project aims to build a new IT infrastructure to achieve the publication of the 2011 Census data on Eurostat website using SDMX standards • It is based on the data sharing architecture where a group of partners agree on providing access to their data according to standard formats and technologies • A data user browses the hub to search for a dataset of interest via structural metadata (dimensions, attributes, measures, code lists, etc). Data are retrieved directly from the interested Member States’ systems

  16. Geostatistics – some general concerns • The user community appears to be still small especially in the statistical offices • The use cases are not established yet • The players in the potential sub elements of the IISD are quite busy (INSPIRE, GMES, SEIS) and preoccupied with their own business

  17. Concept for an integrated web solution / An infrastructure for Geostatistics. (The Subproject 3) Proposal for an application for the discovery of geostatistical data built on INSPIRE and SDMX European Forum for GeoStatistics 2008 in Bled

  18. Statistics SDMX technical standards standard format for data and reference metadata architecture for data exchange SDMX registry Guidelines E.g. how to construct metadata descriptions Freely available implementation tools SDMX Registry SDMX Metadata Converter Spatial data INSPIRE implementing rules Thematic working groups Network services Catalogue service Technical INSPIRE documents A number of commercial and FOSS tools Geonetwork as a catalogue solution Correspondence of INSPIRE and SDMX

  19. Ambition for a first implementation of a geostat application • A catalogue application shall be developed implementing metadata profiles of INSPIRE and SDMX which will allow users to find spatial and statistical data. • Will allow to search for data registered with INSPIRE catalogues and SDMX registries • Will provide a one stop shop for spatial data and statistical data • Will provide a download service for data • (Will allow to visualise datasets in the appropriate format (text, maps, graphs, tables))

  20. Approach • The application needs to implement the SDMX standard and the INSPIRE Implementing rules on network services (based on OGC standards) and metadata • Phases of Work • Definition of the business case (by subproject 1, e.g. from population statistics) • Analysis of the technical infrastructures of INSPIRE and SDMX • Specification of the software requirements • Development of interfaces to INSPIRE and SDMX metadata • Design and implementation of the application

  21. Open questions • Deliverables • A web portal in the form of an INSPIRE geoportal that at the same time can also access SDMX registries. • And? • Users • Potential users will be experts, general public? • Organisations involved and their roles in the proposed work • European Forum for Geostatistics, exact role? • Eurostat (Grant) • Expected Costs and Duration of the Work • Duration: 1 year, cost 100k€, realistic?
