1 S-100 The IHO Geospatial Standard for Hydrographic Data 1st CHRIS / MSDIWG Meeting IHB, Monaco 4 – 5 February 2008

2 S-57 Background DX 87 DX 90 May IHO S-57 - formally adopted (a number of Edition 2 ENC cells produced) November Edition 3.0 (ENC Product Specification Ed 1) Frozen four years to provide stability so that; - HOs could produce ENC data and - OEMs could develop ECDIS equipment November Edition 3.1 released (ENC Product Specification Ed 2) (38 new attribute values added) It was decided that Edition 3.1 would remain frozen until at least November January Edition released (Enhancements Required to Encode S-57 Edition ENC Data). three new feature object classes; three new attributes, and; two new attribute values for Category of Restricted Area. (Presently about Edition 3.1 ENC cells)

3 IHO Definition of Hydrography That branch of applied sciences which deals with the measurement and description of the features of the sea and coastal areas for the primary purpose of navigation and all other marine purposes and activities including (inter alia) offshore activities, research, protection of the environment and prediction services approved by IHO Member States in November 2002

4 Other Users Other communities have developed products based on S-57 AML Inland ENC MIO Open ECDIS Forum Privately registered Producer Codes (not in S-62) mechanism for registering external features and attributes (no longer on the OEF)

5 S-57 Limitations Developed primarily to meet ENC requirement for an IMO compliant ECDIS Inflexible maintenance regime (freezing of editions) Cannot support contemporary requirements (imagery, gridded bathymetry, time-varying information, et cetera) Data transfer mechanisms are limited (data model embedded in encapsulation ( ISO 8211 )) S-57 + ENC Product Specification

6 S-100 The IHO Geospatial Standard for Hydrographic Data S is based on ISO 191xx set of Geospatial Standards (ISO profiles – tailored for hydrographic requirements) - will support a broader spectrum of hydrographic requirements - makes provision for imagery and gridded data (not in S-57) - includes the concept of feature data dictionaries /catalogues (maintained within a registry) - supports the development of multiple Prod Specs and enables them to be maintained independently - supports more that one encoding format (ISO 8211 and GML) S-100 Toolbox

7 S is based on ISO 191xx set of Geospatial Standards (ISO profiles – tailored for hydrographic requirements) Profile set of one or more base standards or subsets of base standards …

8 S-100 makes provision for imagery and gridded data

9 Feature Registers HydroIce NPub InlandOEF Hydro Register FDD F A E Ice Register NPub Register Inland Register OEF Register FDD F A E F A E F A E F A E Register F eature D ata D ictionary F eatures A ttributes Enumerates IHO Registry for S-100 will comprise a collection of registers: S includes the concept of feature data dictionaries /catalogues (maintained within a registry)

10 S-100 will support a broader spectrum of hydrographic requirements contains all the components to make different product specifications for all types of hydrographic data S-101 ENC S-103 ??. S-104 ??. S-100 ???????? ???????? ???????? ????????... S-10?… S-102 ??.

11 S-100 supports the development of multiple Prod Specs and enables them to be maintained independently Determine geometry requirement Feature-based product - determine feature classes - determine feature attributes - determine enumerates - register definitions in appropriate dictionary - bind features and attributes Determine geometry types Create application schema Coverage based product ? - content and structure of the coverage Determine Coordinate Reference System(s) Determine Encoding

12 S-100 Publication – where are we ? Registry has been completed and is on line (http:// /iho_registry/home.php) Draft S-100 components documents – completed at TSMAD 15 (IHB Monaco - 4 to 7 Feb 2008). S-100 component documents are presently being combined into a single document and harmonised/cleaned, etc.. to be made available at end of February March to August – review period (comment sheet will be made available for feedback). Comments to be reviewed at the September 2008 TSMAD meeting and a final version prepared for adoption by CHRIS 20 in November 2008

16 S-100 Publication – where are we ? Some key components still missing: Portrayal component – dependant on the availability of a stable version of ISO Encoding – application schema and encoding formats are being prepared for ISO 8211 and GML, - draft versions will be available late May 2008.

17 Additional Objectives Content and carrier are independent Core standard can evolve through extensions - no need for new versions of product specifications or system revisions –plug and play updating Product Feature Catalogs more flexible and capable of expansion –will accommodate future IMO regulations Will support emerging ECDIS / E-Navigation requirements (integrated Nautical Publications, Inland ENC Product Specs, …..)

18 Derived Benefits S-100 stays in mainstream of GIS greater use and lower cost of implementation Maximizes access to COTS software applications and development New components not developed in isolation Interoperability with other ISO 191 xx based profiles (e.g. NATO, WMO (ice), …) Encourages use of hydro data beyond HOs and ECDIS users (coastal zone mapping, security,…) Plug and Play updating of data, symbology and software enhancements Inclusion of 10 years worth of deferred S-57 corrections and extensions

19 IHO Registry Other Register Metadata Register Data Type Register Symbols Register Feature Registers FDD Features Attributes Enumerates IHO Registry

20 S-100 will support: Imagery and gridded data High-density bathymetry Seafloor classification 3-D and time-varying data (x,y,z and time) Dynamic ECDIS MIOs Marine GIS Web-based services Other applications …………

21 Strong Foundation Built on well established international standards: –ISO /TC211 (130 countries/members) Liaison –DGIWG (military) –OGC (strong industry/web involvement presence) –SDI (Spatial Data Infrastructure) communities IHO will host Registry –registers of hydrographic-related information ( such as feature data dictionaries, data types, metadata)

22 S-57 Edition 3.1 Comprises: Introduction Data Model Data Structure and Format Rules for ISO 8211 encapsulation Appendix A – Object Catalogue Appendix B1 ENC Product Specification Appendix A, Annex A - ENC Producer Codes Appendix B.1, Annex C - Recommended ENC Validation Checks S-62 ENC Producer Codes S-58 Recommended ENC Validation Checks
