    ENCs have been introduced more than a decade ago.
    Coverage has constantly improved.
    ENCs are compiled for use in ECDIS in the first place.
    Background
  • Workshop Bunnik 12 Feb 2010
    5
    ENCs are good for sailing from one Port to another.
    They are not compiled for Navigation in confined waters.
    Usually ENCs do not contain high density bathymetry.
    Background
  • Workshop Bunnik 12 Feb 2010
    6
    ENCs are not only used by ECDIS.
    ECS systems also use ENCs.
    Navigation in confined waters is often done with ECS assistance.
    Dedicated systems are available for high precision operations.
    Background
  • Workshop Bunnik 12 Feb 2010
    7
    To usean ECS for high precision navigation we need:
    Most accurate positioning data.
    Latest bathymetric survey data.
    High density depth information.
    ENCs do not meet these requirements.
    Background
  • Workshop Bunnik 12 Feb 2010
    8
    Example: ENC Depth Areas
    depth between 10m and 20m.
    maintained depth 14.7m

    New chart product for display in Electronic Chart Systems.
    bENCs contain high density bathymetry.
    based on latest hydrographic surveys .
    used in combination with ENCs, IENCs, PENCs.
    bENC - Introduction
  • Workshop Bunnik 12 Feb 2010
    11
    Example: bENC
    • bENC with contour lines and spot soundings.
    • No other nautical information required

    bENCs must be used in combination with Electronic Navigational Charts (ENC).
    ENCs show basic depth information only.
    bENCs add detailed depths information, but they do not replace ENCs.

    Since 2008 regular production of bENCs for the River Elbe.
    Involved German Waterway Authority, the German Hydrographic Office and 7Cs.
    Area of 70 nmis coverd by 7 bENCs.
    Appr. 2 new Editions per week.

    EFFORTS Project (Effective Operations in Ports) 2006 -2009
    Hamburg Port Authority (HPA) was the leader of the sub-project „Port ECDIS“.
    HPA has produced bENCs of the Port Area for integration in Port ECDIS.

    28
    Can‘t ENCs store high density bathymetry?
    Basically yes, but often bathymetric data is subject to frequent changes.
    Short term chart updating required.
    Existing ENC distribution procedures are not suitable.
    Frequently Asked Questions
  • Workshop Bunnik 12 Feb 2010
    29
    Why is the bENC concept so effective?
    Simple and straight forward conversion process.
    Not an elaborate cartographic task.
    Authorities do not have to get involved in “full blown” ENC production.
    Frequently Asked Questions
  • Workshop Bunnik 12 Feb 2010
    30
    Harmonization with ENC production?
    Not required, bENC production is independent from ENC production.
    bENC producer and ENC producer do not have to synchronize their work.
    Frequently Asked Questions
  • Workshop Bunnik 12 Feb 2010
    31
    Will bENCs be supported by S-100?
    bathy ENC will be supported by S-100 (S-100 Info Paper).
    Easy Product Transition from S-57 bENC to S-100 bENC expected.
    Frequently Asked Questions
  • Workshop Bunnik 12 Feb 2010
    32
    What is the difference compared to CLB?
    CLB is AML product (military standard).
    Content is basically the same.
    bENC specification has been optimized for use with ENCs, IENCs and PENCs.
    bENC allows more flexibility.
