  2. What is Motiive About • Premise (of call) • GMES Service will be more cost-effective to deploy through the use and adoption of OGC/ISO Interoperability standards • This interoperability will entail true ‘mix and match’ between (and amongst) ‘core’ and ‘downstream’ data processors. • Scope (of Motiive) • How do you apply ISO/OGC Standards to the coastal/marine community • Land:sea interaction (Marine Overlays on Topology) • What do the standards look like and how does a ‘cost benefit’ manifest itself • Work with RISE MOTIIVE : RISE HAC-PBEC, Brussels, 6th June 2007

  3. Project Update • What is Motiive about? • GMES and INSPIRE Context • ISO and OGC Standards • What has Motiive achieved? • Community needs for harmonisation (need for FT and FTC) • Community Feature Types (published as UML and XSD) • FTC implementation (base catalogue services in place) • Cost-Benefit methodology • Motiive, INSPIRE and OGC • Earth science perspective on Inspire • A catalogue for the Themes to lodge their FT’s • What does Motiive still need to do? (Sept 2007) • Finalisation of catalogue deployment (ebRIM packges) • Submit FT specification as OGC Recommendation MOTIIVE : RISE HAC-PBEC, Brussels, 6th June 2007

  4. Motiive Use Case Jane is contributing to the development of an integrated coastal management plan and needs access to a range of data concerning conditions in the littoral zone and offshore. Jane’s current concern is to investigate sediment transport and coastal erosion in the UK’s Thames estuary. Jane is working in an era of a harmonised spatial data infrastructure and is able to access on-demand a range of data across the internet. Jane wishes to evaluate a variety of tidal models available to her by validating against historical tide gauge measurements. Helga (NO) and Willem (NL) both run tidal models and wish to make their datasets available for re-use – they employ standards-based interoperable web services for this purpose, and these are amongst the datasets available to Jane for evaluation. Data from the selected model is used to generate plots of current and other tidal parameters. None of the data suppliers provide dedicated portrayal services for their data, but a third-party portrayal service is available for a range of compatible ‘base’ feature types. Moreover, another service provides feature-type transformation (defined as an operation on the source feature type) to facilitate direct model-observation inter-comparison. • Generic community needs to use data in a unambiguous way • Clear definitions of what data sets ‘are’ • =>Clear declaration of Feature Types • Clear ‘use’ of datasets • =>Operations on Feature Types (binding to services) MOTIIVE : RISE HAC-PBEC, Brussels, 6th June 2007

  6. ISO Scope • ISO 19101 introduces the Domain Reference Model – an abstract information architecture for geospatial data infrastructures. • At the core of the model is a geospatial Dataset. A Dataset contains Feature instances and related objects, and is described by Metadata. • Feature type definitions may be stored for re-use in feature catalogues (ISO 19110). • Geographic information services operate on a Dataset, while the logical structure and semantic content of a Dataset is described through an Application schema MOTIIVE : RISE HAC-PBEC, Brussels, 6th June 2007

  7. What Motiive as done • Motiive has worked with RISE on a methodology for developing a Data Product Specification (RISE Lead) • MOTIIVE followed this methodology and as output from this process: • Established our community needs for data harmonisation • Formalised our community needs as use cases • Modelled our community Feature Types and realised them as GML application schema • Established a Feature Type Catalogue to lodge the Feature Types Established • The approach we followed will be useful to any community where the datasets exchanged amongst and between members are inherently based on ‘representation on environmental phenomena’ • water quality, air temperature, water flows ETC. MOTIIVE : RISE HAC-PBEC, Brussels, 6th June 2007

  8. Community Harmonisation Needs • Coastal Managers (D7b) • Mainly regional/national managers • Seamless Discovery of data sets • Seamless Use • Meteorological (D9b) • WMO / UK Met Office • (flexible) chaining of services • Maintaining access to legacy data • Integrated Coastal Mapping (D7a) • UKHO / IHO • Common definitions of ‘features’ • Greater ‘quality assurance to a DPS’ • GSE • Marcoast • (flexible) chaining of services • Maintaining access to legacy data MOTIIVE : RISE HAC-PBEC, Brussels, 6th June 2007

Community Harmonisation Needs • Coastal Managers (D7b) • Mainly regional/national managers • Seamless Discovery of data sets Feature Types • Seamless Use Feature Catalogue • Meteorological (D9b) • WMO / UK Met Office • (flexible) chaining of services Feature Catalogue • Maintaining access to legacy data • Integrated Coastal Mapping (D7a) • UKHO / IHO • Common definitions of ‘features’ Feature Catalogue • Greater ‘quality assurance to a DPS’ • GSE • Marcoast • (flexible) chaining of services Feature Catalogue • Maintaining access to legacy data MOTIIVE : RISE HAC-PBEC, Brussels, 6th June 2007

  11. Community Feature Types • Feature Types for ‘Environmental Observations’ • rather that ‘environmental constructions’ • CSML (Climate Science Modelling Language) • Feature types and storage descriptors • Consistent with community practice • ESRI, UniData, NOAA MOTIIVE : RISE HAC-PBEC, Brussels, 6th June 2007

  12. CSML Features Presently in Release 2 MOTIIVE : RISE HAC-PBEC, Brussels, 6th June 2007

  13. CSML Features INSPIRE does not mandate operations for FTs – but most communities will require this MOTIIVE : RISE HAC-PBEC, Brussels, 6th June 2007

  15. Feature Type Catalogues • Feature type definitions may be stored for re-use in catalogues (ISO 19110). • Since features encapsulate important data semantics within communities of practice. • Feature Type Catalogues may be regarded as ‘semantics repositories’ within an overall information architecture. MOTIIVE : RISE HAC-PBEC, Brussels, 6th June 2007

  16. Feature Type Catalogue Semantics can be inherited from other communities –or from within your own. Plus the services that go with it MOTIIVE : RISE HAC-PBEC, Brussels, 6th June 2007
