  1. Implementing INSPIRE UIDs and life-cycle information in a European SDI. Nathalie Delattre , IGN Belgium Work team: Romain Kereneur, IGN, France Noémie Grémeaux, IGN, France Marcus Brühl, BKG, Germany Esa Tiainen, NLS, Finland

  2. User Needs • Maintenance of reference information in user databases. • Not only Unique IDentifiers but also life-cycle information ( get change only updates ) • European contract European users request pan-European datasets with external UIDs and life-cycle information workable at European level within the next three years • EuroBoundaryMap ( Administrative regions at scale 1:100k) • EuroRegionalMap ( Geo topographical data at scale 1:250k) • EuroGlobalMap (Geo topographical data at scale 1:1000k)

  3. Objective To set up European rules/guidelines for implementing UIDs aiming at a better interoperability for at cross-border/pan European level. The technical challenge How to implement UIDs and life-cycle information that are maintained at national level but that must be operable at a pan-European level by enabling incremental update?

  4. European rules for UId implementation • Two types of UIDs : (INSPIRE compliant) • created and maintained by NMCAs : <European namespace> <NMCA localID> - created and maintained at supra national level: <European namespace> <European localID> • Adopt INSPIRE life cycle attributes • versionID • beginLifespanVersion • endLifespanVersion • Same life cycle rules across Europe : 10 life cycle rules defined • Definition of the lifespan cycle of a INSPIRE feature , (new, modified or deleted)

  5. European rules implementation: ideal solution Implementation of external UIDs in NMCAs data systems and contents European data (seamless coverage) European data (national components) Data sources, NMCA External UID management for Cross-border features European external ID + Life cycle attributes External ID + Life cycle attributes European external ID + Life cycle attributes + European namespace Use national localID and life cycle information

  6. European rules implementation: intermediate solution Implementation of external UID over the national spatial data infrastructure European data (national componants) European data (seamless coverage) Data sources, NMCA Change detection process between two releases External UID management for Cross-border features european external ID Life cycle attributes European external ID Life cycle attributes Creation of European localID and life cycle information Different scenarios must be considered depending on the level of progress in implementation of each NMCA to ensure homogeneous and reliable UID and life cycle information delivery in the pan-European databases

  7. UIds implementation at cross-border/pan European level: How this can be achievable, how to proceed? Nathalie Delattre , IGN Belgium

  8. Indicators monitoring the level of progress in UIDs implementation

  9. Monitoring among NMCAs

  10. Monitoring Results Unique Identifier Life-cycle Information Life-cycle Rules

  11. Amended European rules for implementing UIDsbased on monitoring results • UID structure proposed in the European rules has been widely accepted by all NMCAs • Life-cycle attributes: • versionId: optional, • beginLifespanVersion: mandatory, • endLifespanVersion: optional

  12. Life-cycle Rules • Simple rules are mandatory • Complex rules are optional

  13. Implementing European rules on UIds in the light of what is achievable among NMCAS: SHORT TERM PERSPECTIVE change detection process between two data deliveries Level 4 (ESDIN) : UIDs Implemented + life cycle information + all life cycle rules European Level on pan-European products Four levels of progress : NMCAS on Referenc data Level 3 :National UIDs are used and Life cycle rules are compliant and possibly re-numbered when life cycle rules not compliant Level 3: UIDs Implemented + life cycle information + basic life cycle rules Level 2 (INSPIRE): UIDs implemented and INSPIRE compliant Level 1-2:Life-cycle information and UIDs are re-calculated (European localID) Level 1: no UIDs implemented or compliant

  14. Pan-European products level European/cross border community level INSPIRE level What could be achievable in longer term Level 4 (ESDIN) : never in a consensual way Level 3: can be commonly reached with the amended European rules Level 2 : can be commonly reached by all of them European level on pan-European products change detection solution and data versioning NMCAs on Reference Data

  15. Conclusion • INSPIRE regarding UIDs implementation will not sufficiently meet interoperability at European level. • European Rules set up in the framework of the ESDIN project should enable historical versioning of pan-European datasets and incremental update delivery at European level. • Ideal solutions is that NMCAs adopt the European rules for national perspective • If not possible, intermediate solution will be implemented by using a change detection solution and data versioning at European level ( tools) • Change detection tools could be applied to national purpose

  16. Together we are stronger!
