  2. Background • Introduction of the bENC concept • bENC Production Process • ENC versus bENC • ... • Content of Presentation bENC - PPUs & Electronic Charts, Southampton, 12 May 2011

  3. ... • Potential Producers and Users of bENCs • Projects • Frequently Asked Questions • Conclusions • Content of Presentation bENC - PPUs & Electronic Charts, Southampton, 12 May 2011

  4. 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 bENC - PPUs & Electronic Charts, Southampton, 12 May 2011

  5. ENCs are not compiled for Navigation in confined waters. • Usually ENCs do not contain high density bathymetry. • Background bENC - PPUs & Electronic Charts, Southampton, 12 May 2011

  6. 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 bENC - PPUs & Electronic Charts, Southampton, 12 May 2011

  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 bENC - PPUs & Electronic Charts, Southampton, 12 May 2011

  8. Example: ENC Depth Areas depth between 10m and 20m. maintained depth 14.7m bENC - PPUs & Electronic Charts, Southampton, 12 May 2011

  10. 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 bENC - PPUs & Electronic Charts, Southampton, 12 May 2011

  11. Example: bENC • bENC with contour lines and spot soundings. • No other nautical information required bENC - PPUs & Electronic Charts, Southampton, 12 May 2011

  12. Example: bENC and ENC import bENC bENC - PPUs & Electronic Charts, Southampton, 12 May 2011

  14. Source data from Hydrographic Surveys. • DEM Generation: Contours, Soundings. • bENC Production Process bENC - PPUs & Electronic Charts, Southampton, 12 May 2011

  15. S-57 Translation of Contour Lines and and Selected Soundings => „raw“ bENC. • bENC Production Process bENC - PPUs & Electronic Charts, Southampton, 12 May 2011

  16. Add Meta Information: • Data Set Name, Producer, Edition #, ... • Compilation Scale, Sounding Datum, ... • Data Quality. • Automatic creation of depths areas. • bENC Production Process bENC - PPUs & Electronic Charts, Southampton, 12 May 2011

  17. The bENC is finished and ready for use. • bENC Production Process bENC - PPUs & Electronic Charts, Southampton, 12 May 2011

  30. 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 bENC - PPUs & Electronic Charts, Southampton, 12 May 2011

  31. 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 bENC - PPUs & Electronic Charts, Southampton, 12 May 2011

  32. 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 bENC - PPUs & Electronic Charts, Southampton, 12 May 2011
