Much more than ENCs

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
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
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)
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 S101 Next Generation ENC Product Specification)

S-100 will support a greater variety of data sources,
products and services
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
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, …)
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)
IHO Registry for S-100 will be comprised of a collection of registers:

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)
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)

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.
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),
