S-57 LimitationsS-57 Limitations

• Developed to meet ENC requirement for an IMO Developed to meet ENC requirement for an IMO compliant ECDIS (the IMO specifications were in compliant ECDIS (the IMO specifications were in their infancy and not completely defined)their infancy and not completely defined)

• Inflexible maintenance regime (requiring the Inflexible maintenance regime (requiring the freezing of standards)freezing of standards)

• Cannot support future requirements (gridded Cannot support future requirements (gridded bathymetry, time-varying info)bathymetry, time-varying info)

• Data transfer mechanisms limited (data model Data transfer mechanisms limited (data model embedded in encapsulation)embedded in encapsulation)

• Many regard the S-57 standard and the ENC Many regard the S-57 standard and the ENC Product Specification as the same thing Product Specification as the same thing

• Impression in the ENC community that the work Impression in the ENC community that the work undertaken to support other hydrographic products undertaken to support other hydrographic products would radically change the ENC, thus affecting ENC would radically change the ENC, thus affecting ENC production and ECDIS adoptionproduction and ECDIS adoption

• As this was not the goal of the revision work S-57 As this was not the goal of the revision work S-57 Edition 4.0 under development is henceforth Edition 4.0 under development is henceforth designated as S-100, IHO Geospatial Standard for designated as S-100, IHO Geospatial Standard for Hydrographic Data Hydrographic Data

• Any product specifications developed using S-100 Any product specifications developed using S-100 would follow in an S-10would follow in an S-10x x series as they are series as they are produced (e.g S-101 Next Generation ENC Product produced (e.g S-101 Next Generation ENC Product Specification)Specification)

IHO RegistryIHO Registry

IHO Registry for S-100 will be comprised of a collection of registers:

• Initially there will be registers for Initially there will be registers for Hydrographic Info (existing features, Hydrographic Info (existing features, dynamic ice coverage, nautical dynamic ice coverage, nautical publications, Inland ENCs, Open ECDIS)publications, Inland ENCs, Open ECDIS)

• With this flexibility other features (even in With this flexibility other features (even in oher registries) can be specified in a P.S.oher registries) can be specified in a P.S.
