From data harmonisation to data interoperability

This presentation by EuroGeographics outlines the evolution from data harmonisation to interoperability, emphasizing the necessity for a networked, distributed infrastructure that provides easy access to geographic reference data. Key challenges include low interoperability levels in data discovery, access, and integration, which complicate data use. The framework promotes harmonised policies and collaborative agreements among stakeholders to drive the implementation of common specifications and standards across European data custodians.

  1. From data harmonisationto data interoperability Claude.Luzet@EuroGeographics.org Presented by Nick.Land @EuroGeographics.org

  2. a preliminary assumption the primary mandate of EuroGeographics Members (the European NMAs)is to maintain and make available geographic reference data over the national territory

  3. Moving in time and resolution • EuroGeographics (previously CERCO & MEGRIN) early mandate: • Centralised harmonisation at small and medium scale • Today’s mission • Interoperability of large scale data • A networked and distributed infrastructure

  4. Interoperability • Aim : “to provide non-specialist end-users with easy access to, and easy use of the information they need”

  5. Today’s infrastructure DB C • Low level of interoperability in • Discovery (metadata) • Organisational/custodianship and access/use (legal, policy, funding) • Data (standard, availability, content) • Distributed & Heteregeneous resources • Data discovery & evaluation uncertain • Data access & exploitation difficult • Data integration & processing costly DB B Users DB A

  6. Content interoperability • Define specifications for common reference data and metadata based on • user requirements • international standards • existing relevant DBs (European,national or local) DB C DB B Users DB A EuroSpec ISO

  7. Access & use interoperability Harmonisedpolicy DB C • Harmonised data policy based on • EuroSpecifications • user requirements • existing policies (European,national or local) DB B Users DB A EuroSpec

  8. Organisational interoperability Collaborativeagreements Harmonisedpolicy DB C • harmonised policy & spec will • influence the national & local policies and specifications • contribute to establishment of agreements between data custodians DB B Users DB A EuroSpec

  9. Technical (operational) interoperability Collaborativeagreements stake-holders Harmonisedpolicy DB C institutional DB B Harmonisation& integrationmechanisms Users technology DB A EuroSpec content

  10. Spatial data infrastructure • “Theavailability and the unimpeded sharing and use of the required data, according to agreed mechanisms and specifications.”

  11. A model for SDI(s) Content Institutional Stake-holders Technology

  12. SDI component Technology • Standards • Tools • Protocols • Processes

  13. SDI component Content • Metadata • Reference data • Core data • Thematic data

  14. SDI component Institutional • Territory • Legal • Policy • Organisational • Funding

  15. SDI component Stake-holders • Deciders • Industry • Users • Data producers • Value-adders • End-users • Governments • Industry • Citizens

  16. As a conclusion (1) • Europe : an interoperability and SDI laboratory • The ESDI may be a European initiative but, when implemented it can be a global solution

  17. As a conclusion (2) • Timely definition and implementation of the ESDI will not happen without investment in: • Specifications, including prototyping • Policy • Organisation (from local to global)
