1 GSDI 6 conference, , Budapest 1 From data harmonisation to data interoperability Presented by

2 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

3 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

4 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”

5 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)

6 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)

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

11 GSDI 6 conference, , Budapest 11 A model for SDI(s) Content Technology Institutional Stake- holders

12 GSDI 6 conference, , Budapest 12 SDI component SDI component Standards Tools Protocols Processes Technology

13 GSDI 6 conference, , Budapest 13 SDI component SDI component Metadata Reference data –Core data Thematic data Content

14 GSDI 6 conference, , Budapest 14 SDI component SDI component Territory Legal Policy Organisational Funding Institutional

15 GSDI 6 conference, , Budapest 15 SDI component SDI component Deciders Industry Users Stake- holders Data producers Value-adders End-users Governments Industry Citizens

16 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

17 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)
