  1. 1. bENC – a new S-57 Product<br />Friedhelm Moggert-Kägeler, SevenCs GmbH<br />presented by Birgit Heinsen-Knapp<br />at the<br />Workshop Hydrographic Software <br />12 February 2010<br />AJ Bunnik – The Netherlands<br />
  2. 2. Workshop Bunnik 12 Feb 2010 <br />2<br />Background<br />Introduction of the bENC concept<br />bENC Production Process<br />ENCs versus bENCs<br />...<br />Content of Presentation<br />
  3. 3. Workshop Bunnik 12 Feb 2010 <br />3<br />...<br />Potential Producers and Users of bENCs<br />Projects<br />Frequently Asked Questions<br />Conclusions<br />Content of Presentation<br />
  4. 4. Workshop Bunnik 12 Feb 2010 <br />4<br />ENCs have been introduced more than a decade ago.<br />Coverage has constantly improved.<br />ENCs are compiled for use in ECDIS in the first place.<br />Background<br />
  5. 5. Workshop Bunnik 12 Feb 2010 <br />5<br />ENCs are good for sailing from one Port to another.<br />They are not compiled for Navigation in confined waters.<br />Usually ENCs do not contain high density bathymetry.<br />Background<br />
  6. 6. Workshop Bunnik 12 Feb 2010 <br />6<br />ENCs are not only used by ECDIS.<br />ECS systems also use ENCs.<br />Navigation in confined waters is often done with ECS assistance.<br />Dedicated systems are available for high precision operations.<br />Background<br />
  7. 7. Workshop Bunnik 12 Feb 2010 <br />7<br />To usean ECS for high precision navigation we need:<br />Most accurate positioning data.<br />Latest bathymetric survey data.<br />High density depth information.<br />ENCs do not meet these requirements.<br />Background<br />
  8. 8. Workshop Bunnik 12 Feb 2010 <br />8<br />Example: ENC Depth Areas<br />depth between 10m and 20m.<br />maintained depth 14.7m<br />
  9. 9. Workshop Bunnik 12 Feb 2010 <br />9<br />bENC: Background<br />Introduction of the bENC concept<br />bENC Production Process<br />ENCs versus bENCs<br />Potential Producers and Users of bENCs<br />Content of Presentation<br />
  10. 10. Workshop Bunnik 12 Feb 2010 <br />10<br />New chart product for display in Electronic Chart Systems.<br />bENCs contain high density bathymetry.<br />based on latest hydrographic surveys . <br />used in combination with ENCs, IENCs, PENCs.<br />bENC - Introduction<br />
  11. 11. Workshop Bunnik 12 Feb 2010 <br />11<br />Example: bENC<br /><ul><li>bENC with contour lines and spot soundings.
  12. 12. No other nautical information required</li></li></ul><li>Workshop Bunnik 12 Feb 2010 <br />12<br />Example: bENC and ENC<br />import<br />bENC <br />
  13. 13. Workshop Bunnik 12 Feb 2010 <br />13<br />bENC: Background<br />Introduction of the bENC concept<br />bENC Production Process<br />ENCs versus bENCs<br />Potential Producers and Users of bENCs<br />Content of Presentation<br />
  14. 14. Workshop Bunnik 12 Feb 2010 <br />14<br />Source data from Hydrographic Surveys.<br />DEM Generation: Contours, Soundings.<br />bENC Production Process<br />
  15. 15. Workshop Bunnik 12 Feb 2010 <br />15<br />S-57 Translation of Contour Lines and and Selected Soundings => „raw“ bENC.<br />bENC Production Process<br />
  16. 16. Workshop Bunnik 12 Feb 2010 <br />16<br />Automatic creation of depths areas.<br />Add Meta Information:<br />Data Set Name, Producer, Edition #, ...<br />Compilation Scale, Sounding Datum, ...<br />Data Quality.<br />bENC Production Process<br />
  17. 17. Workshop Bunnik 12 Feb 2010 <br />17<br />The bENC is finished and ready for use.<br />bENC Production Process<br />
  18. 18. Workshop Bunnik 12 Feb 2010 <br />18<br />Example: bENC in ECS Display<br />
  19. 19. Workshop Bunnik 12 Feb 2010 <br />19<br />Background<br />Introduction of the bENC concept<br />bENC Production Process<br />ENCs versus bENCs<br />Potential Producers and Users of bENCs<br />Content of Presentation<br />
  20. 20. Workshop Bunnik 12 Feb 2010 <br />20<br />bENCs must be used in combination with Electronic Navigational Charts (ENC).<br />ENCs show basic depth information only. <br />bENCs add detailed depths information, but they do not replace ENCs. <br />ENC versus bENC<br />

  23. 23. Workshop Bunnik 12 Feb 2010 <br />23<br />Pilots using PPU equipment.<br />Vessel Traffic Management Systems. <br />Marine Simulators.<br />Special software used for navigation in confined waters.<br />Potential Users of bENCs<br />

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

  34. 34. Workshop Bunnik 12 Feb 2010 <br />34<br />Perfect method for the integration of high density bathymetry in electronic charts.<br />Additional value for ECS systems that are used in confined waters.<br />Simple andstraight forward production.<br />S-100 compatible.<br />Conclusions of bENC concept<br />
