  1. IHO S-100Much more than ENCs Barrie Greenslade Chair IHO TSMAD, United Kingdom Hydrographic Office February, 2007

  2. Reference • The material for this presentation was extracted from a paper entitled “Development of IHO S-100 IHO Geospatial Standard for Hydrographic Data” by L. Alexander, M. Brown, B. Greenslade and A. Pharaoh

  3. History • IHO S-57 formally adopted May 1992 • Edition 3.0 was released November 1996 • ENC Product Specification 1.0 • Minor Revision 3.1 released November 2000 • ENC Product Specification 2.0 • Supplement 3.1.1 released January 2007 to cater for new IMO requirements • ENC is the main product specification supported • Two derivatives – AML and Inland ECDIS

  4. S-57 Limitations • Developed to meet ENC requirement for an IMO compliant ECDIS (the IMO specifications were in their infancy and not completely defined) • Inflexible maintenance regime (requiring the freezing of standards) • Cannot support future requirements (gridded bathymetry, time-varying info) • Data transfer mechanisms limited (data model embedded in encapsulation)

  5. New Name  S-100 • Many regard the S-57 standard and the ENC Product Specification as the same thing • Impression in the ENC community that the work undertaken to support other hydrographic products would radically change the ENC, thus affecting ENC production and ECDIS adoption • As this was not the goal of the revision work S-57 Edition 4.0 under development is henceforth designated as S-100, IHO Geospatial Standard for Hydrographic Data • Any product specifications developed using S-100 would follow in an S-10x series as they are produced (e.g S-101 Next Generation ENC Product Specification)

  6. AML S-101 Next GenENC InlandENC MIO BathyENC 3D &Temporal Nautical Pubs ICE Gridded S-100 S-100 will support a greater variety of data sources, products and services

  7. Support Greater Variety • Includes: • Imagery and gridded data • 3-D and time-varying data (x,y,z and time) • MIOs, Other • In support of: • Dynamic ECDIS • High-density bathymetry • Seafloor classification • Marine GIS • Web-based services

  8. Additional Objectives • No permanent tie to single exchange mechanism (take advantage of contemporary technologies  web • Evolve core standard through extensions without continued need for producing new versions of product specifications or system revisions (and … re-generating, re-distributing, re-loading … the data in the new version) • Product Feature Catalogs that are more flexible and capable of expansion (e.g. new IMO regulation) • New features in support of richer ECDIS experience (e.g. Nautical Publications, Inland ENC Product Specs, …)

  9. Strong Foundation • Built on strong international standards: • ISO /TC211 with 130 countries/members • In liaison with DGIWG (military), OGC (strong industry/web involvement presence) and GDSI (Global Spatial Data Infrastructure) • Harmonized data content between S-100 and NATO DIGEST • IHO will host Registry  facility to store/access various registers of hydrographic-related information ( such as feature concept dictionaries, data types, metadata)

  10. Other Register Metadata Register Symbols Register A A A A F F F F E E E E Attributes Enumerates Features Features Attributes Enumerates IHO Registry Data Type Register Feature Registers FDD IHO Registry for S-100 will be comprised of a collection of registers: Feature Registers Hydro Ice Inland ECDIS OEF NPub NPub Hydro OEF Inland Ice Register Register Register Register Register FDD FDD FDD FDD FDD A F E Register Feature Data Dictionary

  11. Registry/Register • Initially there will be registers for Hydrographic Info (existing features, dynamic ice coverage, nautical publications, Inland ENCs, Open ECDIS) • With this flexibility other features (even in oher registries) can be specified in a P.S. • Even if new item is registered, a new version of current P.S. not required • Operational Registry available (www. ukhoftp.gov.uk/iho_registry)

  12. S-100 Benefits • Using defined standards ensures S-100 stays in mainstream of geospatial info industry  greater use and lower cost of implementation/use • Conformance to defined standards maximizes COTS software applications and development • New components not being developed in isolation • Interoperability with other ISO/TC211 based profiles (e.g. NATO DIGEST, ICE, weather, …) • Greater usage of data (beyond HOs and ECDIS users) hence greater HO leverage/support for extended coverage and operations • Enhanced usage (coastal zone mapping, security,…) • “Plug and Play” updating of data, symbology and software enhancements. • Inclusion of 10 years worth of corrections and extensions (deferred)

  13. Timeline for S100/S101 • December 2007 – S100 Published • 2007 – Commence development of S-101 • Begin User Outreach with OEM’s, Production software, Mariners • 1st Quarter 2007 – Begin Requirements for ENC Product Specification • 4th Quarter 2007 Initial Requirements gathering completed • Early 2008 – Publish S102 Tidal Harmonics Product Specification • 1st Quarter 2008 – Begin First Draft of S-101 • 2nd Quarter 2008 – Complete First Draft of S-101 • 4th Quarter 2008 – Committee Draft of S-101 completed • Impact Analysis • Production Software (HO’s, Software companies) • OEM’s • End Users – Training establishments • Type Approval

  14. Timeline Cont. 2007 – 2010 – Coordination Group on ECDIS • Standards Alignment • IMO Performance Specification • IEC 61174 • IEC 62288 • IHO S-52 - CSMWG • IHO S-63 – DPSWG • 4th Quarter 2010 – Final Draft of S-101 approved by TSMAD (DATS) • 2011 – Approval of S-101 by CHRIS (HSSC) • 2012 – Approval by IHO member states at the Conference • 2012 – S101 available for Implementation

  15. Target • As a consequence of the extensive development process, any improved ENC Product Specification (S-101) could not come into force before at least 2012 and even then, the standard would sit alongside the existing S-57 Edition 3.1 Product Specification for some time. Furthermore, it is intended that any ECDIS which are upgraded to use S-101 ENCs will continue to be able to use S-57 Edition 3.1 ENCs as well.

  16. Migration from S-57 to S-100 • S57 3.1 will continue to be used for many years even with S-100 release • Opportunity to use other PS (e.g. gridded) with existing ENC PS as overlay • Will be done with inclusion of all interested parties (hence workshop(s), IHO S-100 Discussion Forum
