4 bENC - PPUs & Electronic Charts, Southampton, 12 May 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

5 bENC - PPUs & Electronic Charts, Southampton, 12 May ENCs are not compiled for Navigation in confined waters. Usually ENCs do not contain high density bathymetry. Background

6 bENC - PPUs & Electronic Charts, Southampton, 12 May Type approved ECDIS must use ENCs. ECS Systems (e.g. PPUs) also use ENC. Navigation in confined waters is often done with ECS assistance. Dedicated systems are available for high precision operations. Background

7 bENC - PPUs & Electronic Charts, Southampton, 12 May 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

8 bENC - PPUs & Electronic Charts, Southampton, 12 May Example: ENC Depth Areas maintained depth 14.7m depth between 10m and 20m.

9 bENC - PPUs & Electronic Charts, Southampton, 12 May bENC: Background Introduction of the bENC concept bENC Production Process ENC versus bENC Potential Producers and Users of bENCs Content of Presentation

10 bENC - PPUs & Electronic Charts, Southampton, 12 May Complementary chart product for display in Electronic Chart Systems. bENCs contain high density bathymetry. based on latest hydrographic surveys. used in combination with ENCs, IENCs, other. bENC - Introduction

11 bENC - PPUs & Electronic Charts, Southampton, 12 May Example: bENC bENC with contour lines and spot soundings. No other nautical information required

12 bENC - PPUs & Electronic Charts, Southampton, 12 May Example: bENC and ENC import bENC

13 bENC - PPUs & Electronic Charts, Southampton, 12 May bENC: Background Introduction of the bENC concept bENC Production Process ENC versus bENC Potential Producers and Users of bENCs Content of Presentation

14 bENC - PPUs & Electronic Charts, Southampton, 12 May Source data from Hydrographic Surveys. DEM Generation: Contours, Soundings. bENC Production Process

15 bENC - PPUs & Electronic Charts, Southampton, 12 May S-57 Translation of Contour Lines and and Selected Soundings => „raw“ bENC. bENC Production Process

16 bENC - PPUs & Electronic Charts, Southampton, 12 May Add Meta Information:  Data Set Name, Producer, Edition #,...  Compilation Scale, Sounding Datum,...  Data Quality. Automatic creation of depths areas. bENC Production Process

17 bENC - PPUs & Electronic Charts, Southampton, 12 May The bENC is finished and ready for use. bENC Production Process

18 bENC - PPUs & Electronic Charts, Southampton, 12 May Example: bENC in ECS Display

19 bENC - PPUs & Electronic Charts, Southampton, 12 May Example: tide aware bENC

20 bENC - PPUs & Electronic Charts, Southampton, 12 May Background Introduction of the bENC concept bENC Production Process ENC versus bENC Potential Producers and Users of bENCs Content of Presentation

21 bENC - PPUs & Electronic Charts, Southampton, 12 May bENCs must be used in combination with ENCs. ENCs show basic depth information only. bENCs add detailed depths information, but they do not replace ENCs. ENC versus bENC

22 bENC - PPUs & Electronic Charts, Southampton, 12 May Background Introduction of the bENC concept bENC Production Process ENC versus bENC Potential Producers and Users of bENCs... Content of Presentation

23 bENC - PPUs & Electronic Charts, Southampton, 12 May Port Authorities Waterway Authorities Hydrographic Offices  Authorities in charge of ensuring navigational safety of the waterways. Potential Producers of bENCs

24 bENC - PPUs & Electronic Charts, Southampton, 12 May Pilots using PPU equipment. Vessel Traffic Management Systems. Marine Simulators. Special software used for navigation in confined waters. Potential Users of bENCs

25 bENC - PPUs & Electronic Charts, Southampton, 12 May Potential Producers and Users of bENCs Projects Frequently Asked Questions Conclusions Content of Presentation

26 bENC - PPUs & Electronic Charts, Southampton, 12 May 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 covered by 7 bENCs. Appr. 2 new Editions per week. Project „River ELBE“

27 bENC - PPUs & Electronic Charts, Southampton, 12 May Projects (bENCs River Elbe)

28 bENC - PPUs & Electronic Charts, Southampton, 12 May EFFORTS Project (Effective Operations in Ports) Hamburg Port Authority (HPA) was the leader of the sub-project „Port ECDIS“. HPA produces and maintains bENCs for integration in Port ECDIS. Project „EFFORTS-Port ECDIS“

29 bENC - PPUs & Electronic Charts, Southampton, 12 May Potential Producers and Users of bENCs Projects Frequently Asked Questions Conclusions Content of Presentation

30 bENC - PPUs & Electronic Charts, Southampton, 12 May 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

31 bENC - PPUs & Electronic Charts, Southampton, 12 May Is it worth the extra work that is required? 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

32 bENC - PPUs & Electronic Charts, Southampton, 12 May 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

33 bENC - PPUs & Electronic Charts, Southampton, 12 May Will bENCs be supported by S-100? bathy ENC mentioned as an IHO S-100 component 1. Easy Product Transition from S-57 bENC to S-100 bENC to be expected. Frequently Asked Questions 1 IHO S-100 The Universal Hydrographic Data Model (IHO Information Paper S-100 )

34 bENC - PPUs & Electronic Charts, Southampton, 12 May Potential Producers and Users of bENCs Projects Frequently Asked Questions Conclusions Content of Presentation

35 bENC - PPUs & Electronic Charts, Southampton, 12 May Perfect method for the integration of high density bathymetry in electronic charts. Additional value for ECS systems that are used in confined waters. Simple and straight forward production. S-100 compatible. Conclusions of bENC concept
