From data harmonisationto data interoperability Claude.Luzet@EuroGeographics.org Presented by Nick.Land @EuroGeographics.org
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
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
Interoperability • Aim : “to provide non-specialist end-users with easy access to, and easy use of the information they need”
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
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
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
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
Technical (operational) interoperability Collaborativeagreements stake-holders Harmonisedpolicy DB C institutional DB B Harmonisation& integrationmechanisms Users technology DB A EuroSpec content
Spatial data infrastructure • “Theavailability and the unimpeded sharing and use of the required data, according to agreed mechanisms and specifications.”
A model for SDI(s) Content Institutional Stake-holders Technology
SDI component Technology • Standards • Tools • Protocols • Processes
SDI component Content • Metadata • Reference data • Core data • Thematic data
SDI component Institutional • Territory • Legal • Policy • Organisational • Funding
SDI component Stake-holders • Deciders • Industry • Users • Data producers • Value-adders • End-users • Governments • Industry • Citizens
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
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)
