GSDI 6 conference, , Budapest 1 From data harmonisation to data interoperability Presented by
GSDI 6 conference, , Budapest 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
GSDI 6 conference, , Budapest 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
GSDI 6 conference, , Budapest 4 Interoperability Aim : “to provide non-specialist end- users with easy access to, and easy use of the information they need”
GSDI 6 conference, , Budapest 5 Today’s infrastructure DB A DB B DB C Users Distributed & Heteregeneous resources Data discovery & evaluation uncertain Data access & exploitation difficult Data integration & processing costly Low level of interoperability in Discovery (metadata) Organisational/custodianship and access/use (legal, policy, funding) Data (standard, availability, content)
GSDI 6 conference, , Budapest 6 Content interoperability DB A DB B DB C ISO EuroSpec Users Define specifications for common reference data and metadata based on user requirements international standards existing relevant DBs (European, national or local)

GSDI 6 conference, , Budapest 8 DB A DB B DB C EuroSpec Users Harmonised policy Collaborative agreements harmonised policy & spec will influence the national & local policies and specifications contribute to establishment of agreements between data custodians Organisational interoperability

GSDI 6 conference, , Budapest 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
GSDI 6 conference, , Budapest 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)
