ECDIS and its Potential for Safer Navigation

• Marine Electronic Highway (MEH)
• Power of ECDIS lays in integration of databases
• Delivering INTERNET onboard at low cost is key
  Organize bridge for real time information
• Optimize use of smart data in an enhanced
  intelligent marine transportation system for
  safer navigation, environmental protection and
  marine transportation efficiency

Ice In ECDIS Vision

• In the far northern and southern hemispheres ice
  is a major factor in safe navigation and the
  integration of real time or near real-time ice
  information into ECDIS is an important and
  natural step.
• To achieve this vision one primary requirement is
  the development of an ICE feature data dictionary
  to work with ECDIS.

Ice In ECDIS - History
After many years of effort an ICE Feature Data
Dictionary is now available as a register
compatible with IHO and others

• 1992 Workshop S57 Object Catalogue - Ottawa
• 1995 Workshop Standards for Ice Information in
  ECDIS - Ottawa
• Draft Ice Object Catalogue, Version 1.0
• 1996 Workshop ECDIS in Ice Navigation Hamburg
• Ice Object Catalogue, Version 2.0
• 1999 The ECDIS Ice Chart Project, SevenCs AG
  Co.
• 2000 Ice In ECDIS Workshop St. Johns, NFLD
• Ice Object Catalogue, Version 3.0
• 2002 Integration of Sea Ice into ECDIS,
  University of New Brunswick Project
• 2004 DGIWG develops structure for Feature Data
  Dictionary Register (Draft)
• 2005 IHO Ice Registry (Draft)

Why Registers and Registries?

• Fundamentally, a register is little more than a
  managed list which assists in defining and
  implementing good business practices
• Objective is to rethink what we currently do,why
  we do it, and how wed rather be doing it
• Three major business problems
• Content update/release is slow
• Cycle time must be in weeks, not months/years
• There will be more than one domain data
  dictionary
• E.g., feature data dictionaries DGIWG FADD,
  military profiles of FADD
• S57 Feature Object Data Dictionary, ICAO
  aeronautical features, environmental features,
  etc.
• Concepts may come from multiple sources and be
  managed by different authorities
• Problem is multi-level bigger than a base
  level catalogue
• Consider features and attributes
• Need feature data dictionaries for definitions,
  feature catalogues tobind features and
  attributes to support product specifications
  (and/or feature information content
  specifications)
• And mappings between different feature
  catalogues/data product specifications to allow
  for interworking

and then leveraging technology -- a means to
the ends, not an end ?
Change management model, develop better tools,
improve access
Use source referencing and compound registers to
pull them together
Layered family of registers with downward
dependencies upward reuse
12
Registr(ies) Model is ISO based
Note MGCP is the military Multinational
Geospatial Co Production project
13
Registry Management
A Registry is the system that supports the
Register

• Registry Owner
• Primary responsibility for the management,
  dissemination and intellectual content of the
  registry
• Registry User
• Any person or organization interested in
  accessing or influences the content of the
  register
• Registry Manager
• Responsible for the administration of the
  registry content. Follows ISO 19135

IHO will establish a compound register that may
contain multiple registers for different domains
in one registry. This will include ICE features
and attributes.

ISO 19135
Procedures for registration of items of
geographic information
Specifies procedures to be followed in
establishing, maintaining, and publishing
registers of unique, unambiguous and permanent
identifiers and meanings that are assigned to
items of geographic information

• Roles and responsibilities in register management
• Register management process
• Extensible UML schema
• Simple, multi-part, hierarchical structures
• Cultural and linguistic adaptability
• Unique, non-reusable register identifiers
• Item lifecycle
• Proposed, Valid (Clarified), Amended (Superceded,
  Retired)

22
ISO 19110
Methodology for feature cataloguing
Defines the methodology for cataloguing feature
types specifies how the classification of
feature types is organized into a feature
catalogue and presented to the users of a set of
geographic data.

• IHO ECDIS feature catalogue (per S-57) complies
  with this ISO standard.
• ICE features can be used with S-57 features to
  build compliant feature catalogues.

23
Registry Implementation

• General approach
• Schemas engineered in UML (Rational Rose)
• Prototype implementations in relational DBMS
• MS Access, Oracle, MySQL
• Feature data dictionary registries
• multi part for DGIWG (DGIWG products)
• 4 part for IHO (S57, OEF, ICE, AML)
• Coordinated prototypes completed in Spring 05
• Based on 19135 DIS and 19126 CD
• Focus on content and management interfaces
• External interfaces are currently (file)
  report-based
• Future
• XML-based content encoding (for interchange)
• Services-interface?

International Ice Services Organizations

• JCOMM1 Expert Team on Sea Ice (ETSI)
• 11 Countries (Both Hemispheres)
• Formerly a sub-group of the WMO, and recognized
  as the body responsible for international ice
  information standards
• Proposed as the owner of the Ice Objects
  Register2
• Next Meeting in Halifax, Canada, October 2005.
• International Ice Charting WG (IICWG)
• 10 Member Countries (N. Hemisphere) overlap with
  ETSI
• Ad-hoc WG to coordinate data/product exchange,
  operational procedures, training, forecasting,
  RD
• Makes recommendations on standards to ETSI
• Baltic Sea Ice Meeting (BSIM)
• Global Digital Sea Ice Data Bank
• North American Ice Service
• Canadian Ice Service, U.S. National Ice Center,
  Intl Ice Patrol
• And Others.
• 1 Joint WMO/IOC Technical Commission for
  Oceanography and Marine Meteorology

Approval of ICE Register

• Content of ICE Register presented to the JCOMM
  Expert Team on Sea Ice (ETSI
• Content will be reviewed by the ETSI team.
  Deadline for comments to be set at the ETSI
  meeting.
• Comments on the ICE register prepared by the
  TSMAD in spring 2004 were primarily editorial or
  related to integration with S-57 objects and have
  already been included in the register.
• ICE Catalogue document V 3 has not been updated
  yet awaiting review of the register and a single
  baseline document will be prepared when the
  register is reviewed by the Ice Committee.
  (differences are primarily editorial)
• The draft implementation of the ICE register has
  been mounted by the UKHO at http//195.217.61.120/
  .

26
Conclusions and Recommendations

• The technology to produce and view ice objects
  exists (e.g. CARIS (GIS) and OSL (ECDIS)).
• The Ice Object and Presentation Specifications
  exist (e.g. IHO and AML).
• Promote the Ice Object Registry.
• Encourage/Help National Ice Services to
  use/expand the Ice Registry
• Develop a Demonstration Project
• Baltic Sea or St. Lawrence River? (Ice already
  planned to be a minor part of the lower St
  Lawrence integrated chart project)
• How to Kick start? (Military and/or Coast Guard
  support)
