• 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 use an 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
maintained depth 14.7m
depth between 10m and 20m.

• 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

• Source data from Hydrographic Surveys.
• DEM Generation: Contours, Soundings.
bENC Production Process
Workshop Bunnik 12 Feb 2010 15
• S-57 Translation of Contour Lines and
and Selected Soundings => „raw“ bENC.
bENC Production Process
Workshop Bunnik 12 Feb 2010 16
• Automatic creation of depths areas.
• Add Meta Information:
Data Set Name, Producer, Edition #, ...
Compilation Scale, Sounding Datum, ...
Data Quality.
bENC Production Process
Workshop Bunnik 12 Feb 2010 17
• The bENC is finished and ready for use.

• 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.

Authorities in charge of ensuring
navigational safety of the waterways.
Potential Producers of bENCs
Workshop Bunnik 12 Feb 2010 23
• Pilots using PPU equipment.
• Vessel Traffic Management Systems.
• Marine Simulators.

• Since 2008 regular production of bENCs
for the River Elbe.
• Involved German Waterway Authority, the
German Hydrographic Office and 7Cs.
• Area of 70 nm is coverd by 7 bENCs.
• Appr. 2 new Editions per week.
Projects
Workshop Bunnik 12 Feb 2010 26
• 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.

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.
