      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.

      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.

      Perfect method for the integration of high density bathymetry in electronic charts.
      Additional value for ECS systems that are used in confined waters.
      Simple andstraight forward production.
      S-100 compatible.
