  12. EuroGeographics Vision Achieve interoperability of European mapping (and other GI) data within 10 years

  13. The 12 INSPIRE policy principles (1) • The European Spatial Data Infrastructure shall be built upon a network of National Spatial Data Infrastructures; • INSPIRE’s technical architecture shall be designed to meet the needs of all stakeholders; • Datasets made available to harmonised data specifications and to common standards; • Data Quality procedures to ensure fitness for purpose and use; • Discovery metadata will be made available at no charge to help users identify and locate INSPIRE datasets; • Reference data will provide the underpinning framework to which all other INSPIRE data will be referenced.

  14. The 12 INSPIRE policy principles (2) • Thematic data will be made available to common standards; • INSPIRE data shall be made available for access and view without charge and on harmonised terms and conditions throughout the European Union; • Sustainable funding and investment mechanisms shall be put in place and maintained by Member States; • Harmonised licensing framework will optimise sharing and trading of georeferenced thematic information; • Unimpeded flow of data and information at local, regional, national and international; • Management and organisation of INSPIRE shall be based on the principles of subsidiarity and proportionality.

  15. Include here the vision graphics

  16. Achieving the vision : metadata • The first step • History : GDDD since 1996 • ‘modernisation’ in progress, synergies with INSPIRE portal, and national initiatives

  17. Achieving the vision : Pricing & Licensing • Rationale : • There is no value of the harmonised data if customers are not able access and to use it • Objectives : • Create licensing terms similar enough to remove legal obstacles to regional/European products • Comparable pricing policy - not similar prices • Issues of data access, usage and dissemination terms are considered on the same priority (if not higher) than the work on the common specifications

  18. EuroSpec Vision Users DB C Owndata Euro Reference Data DB B Euro Metadata DB A EuroSpec Pricing & Licensing policy ISO Legal Framework

  19. EuroSpec objectives • Develop agreed specifications (data content and data model ) for common reference data; • Build a community of key stakeholders (including customers, system and application developers, and other project partners) and involve them in the development and implementation testing of the specifications;

  20. EuroSpec objectives (cont’d) • Test the feasibility of implementing the specifications through development of prototypes - “ to learn by doing”; and, • Develop implementation guidelines for NMAs to ensure national datasets can be transformed to the European specification(s).

  21. Scope (content) • Common Reference Data • Units of administration • Units of property rights (parcels, buildings) • Addresses • Selected topographic themes (hydrography, transport, height,…) • Orthoimagery • Gazetteer • Coordinate systems

  22. Scope (resolution) • Feature catalogue • Scale-less • Data structure, data models • Focus on large scale (1:10.000) • Address other required scale ranges • Medium : 1:25k ~ 1:50k • Small : 1:100k ~ 1:1M • Options, issues • Object based, unique identifier • Connected topology, shared topology, • Edge matching • 3D, time stamp

  23. State of the art (1) • Most reference data components are available in Europe, provided by an average of 2 organisations per country

  24. Producers of reference data sets 2 1 1 2 1 2 3 4 1 4 1 18 1 Total of 68 organiza-tions in 26 countries 2 1 2 2 2 2 3 1 1 3 2 1 3

  25. State of the art (2) • Most reference data components are available in Europe, provided by an average of 2 organisations per country • Most larger scale national ‘topographic’ databases are at scale 1:10.000

  26. Scale of topographic databases Note1: Switzerland has also 60 % of data in scale 1:1000 Note2: GB has several scales (29 % 1:1250, 68 % 1:2500, 3 % 1:10000)

  27. State of the art (3) • Most reference data components are available in Europe, provided by an average of 2 organisations per country • Most larger scale national ‘topographic’ databases are at scale 1:10.000 • Topographic data is generally not object based, but there is a definite trend to change towards object based structures • National DBs are generally not based on international standards.

  28. Seamless Administrative Boundariesof Europe Early steps : SABE • The first European commercial product from NMAs • It was started in 1992: v1991, v1995, v1997, 2001 Census (released Feb 2003) • The most detailed admin. units from “official sources” • Cross-border data with uniform structure and in one reference system • 32 countries

  29. Early steps : EuroGlobalMap • Global (1:1m) scale • Network approach to creation through regional coordinators • Target for delivery: • June 2003 ~ 20 countries • End 2003~ 30-35 countries http://www.eurogeographics.org/egm

  30. Early steps : EuroRegionalMap • Regional/national scale (1:250k) • Prototype dataset covering 7 countries • Target for delivery is October 2003 • Aim to expand coverage http://www.eurogeographics.org/erm
