1. GSDI 6 conference, 16-19.09.2002, Budapest 1 From data harmonisation to data interoperability Claude.Luzet@EuroGeographics.org Presented by Nick.Land @EuroGeographics.org

2. GSDI 6 conference, 16-19.09.2002, 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

3. GSDI 6 conference, 16-19.09.2002, 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

4. GSDI 6 conference, 16-19.09.2002, Budapest 4 Interoperability Aim : “to provide non-specialist end- users with easy access to, and easy use of the information they need”

5. GSDI 6 conference, 16-19.09.2002, 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)

6. GSDI 6 conference, 16-19.09.2002, 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)

7. GSDI 6 conference, 16-19.09.2002, Budapest 7 DB A DB B DB C EuroSpec Users Harmonised policy Access & use interoperability Harmonised data policy based on EuroSpecifications user requirements existing policies (European, national or local)

8. GSDI 6 conference, 16-19.09.2002, 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

9. GSDI 6 conference, 16-19.09.2002, Budapest 9 Technical (operational) interoperability DB A DB B DB C EuroSpec Users Harmonised policy Collaborative agreements Harmonisation & integration mechanisms content technology stake-holders institutional

10. GSDI 6 conference, 16-19.09.2002, Budapest 10 Spatial data infrastructure “The availability and the unimpeded sharing and use of the required data, according to agreed mechanisms and specifications.”

16. GSDI 6 conference, 16-19.09.2002, 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

17. GSDI 6 conference, 16-19.09.2002, 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)
