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

Why S-100 ?

Join mainstream GIS
–





maximizes access to COTS software and development
interoperability with other ISO 19100 based profiles
new components not developed in isolation
easier use of hydro data beyond HOs and ECDIS users
- coastal zone mapping, security, inundation modeling, …
extensible and active feature catalogue registry
Plug-and-Play updating of data, symbology and software
enhancements
Last updated Dec 2010
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 maritime data applications …

S-100
Framework Data Structure
for Hydrographic and Related Data
–
broad geospatial framework structure
–
–
–
–
Not specific to ECDIS or charting
Capable of accommodating other requirements
Increasing interest from prospective e-Navigation data
providers
Based on ISO 19100 series of geographic standards
Last updated Dec 2010
S-100 - built on ISO 19100
Naming: S-57 e4.0  S-100


S-57 is NOT the ENC Product specification
S-100 is NOT the ENC Product specification
S-57 and S-100 : generic framework standards for
hydrographic and related information
Last updated Dec 2010
Additional Objectives


Content and carrier are independent
No need for new versions of product specifications or
system revisions
–

Product Feature Catalogs more flexible and capable of
expansion
–

Plug-and-play updating
can accommodate future IMO requirements
Will support emerging ECDIS / e-Navigation
requirements
–
integrated Nautical Publications, Inland & Port ENC Product Specs, etc
Last updated Dec 2010
Strong Foundation

Built on established international standards:
–


ISO /TC211 (130 countries/members)
Liaison
–
DGIWG (military)
–
OGC (strong industry/web involvement presence)
–
SDI (Spatial Data Infrastructure) communities
IHO is hosting the ISO compliant Registry
–
Contains registers of hydrographic-related information (such as
feature content dictionaries, data types, metadata, etc)
Last updated Dec 2010
S-100 Registry

accessible via IHO website: www.iho.int
Last updated Dec 2010
Registry and Registers

Management procedures in IHO S-99

Registers organised under “domains”
(
– hydrographic features, sea ice coverage, nautical publications, Inland ENCs, etc

)
Registry open to extension and use by other submitting
organizations
–
–
Submitting organizations propose then regulate their domain
data - via domain control body
All features tagged with domain “owner”
Last updated Dec 2010
Open Participation

Is what you want already in the S-100 registry?
–

Then use it !
Not in the registry ?
–
Then, find or become a submitting organization to :
–
–
–
propose a revision
propose something new
propose to establish a new domain

S-101 – next generation ENC
Standard for future Electronic Navigational Charts
Based on concepts in S-100
– S-57 ed3.1 data will be usable in S-101 compliant ECDIS
systems
– Will incorporate all the data included in S-57 ENC
– Will allow for plug and play updating of data, symbology and
software enhancements

Migration from S-57 to S-100



Cooperation with all interested parties
(workshops, IHO S-100 Discussion Forum, …..)
S-57 ed3.1 will continue to be used for many years even
after S-100 release
Opportunity to use S-100 based Prod Specs (e.g. gridded
bathy) with S-57 ENC Prod Spec via data overlays
Last updated Dec 2010
Impact on S57 e3.1 ENCs



S-101 ENC Product Specification will not come into
force until at least 2012
S-101 ENC will sit alongside the existing S-57 e3.1
ENC Product Specification for some time
ECDIS equipment which are upgraded to use S-101
ENCs will be able to use S-57 e3.1 ENCs
Last updated Dec 2010
Summary
S-100
 Will enable wider use and transfer of hydrographic data
than S-57
 Registry open to extension and use by other submitting
organizations
 Will better support new/emerging requirements
 Is aligned with a contemporary standard (ISO 19100)
 Will NOT make S-57 ENCs obsolete
 Will not require HO’s to change to S-100 in the near
future
