IHO CL 55 /201 7 dated 31 October - Outcome of the First Meeting of the IHO Council . Dear Hydrographer, Following the publication of Edition 4.0.0 of IHO Publication S- 57 Appendix B.1, Annex A – Use of the Object Catalogue for ENC ( Reference A ), the ENC Maintenance Working Group (ENCWG) has continued to maintain this publication as directed by its programme of work. The working group noted that there had been a number of clarifications and revisions made to the document resulting from feedback from ENC and ECDIS users, papers to ENCWG meetings and enquiries from H ydrographic O ffice s and industry since the publication of Edition 4.0.0. While many of these changes had been promulgated by ENC Encoding Bulletins and Frequently Asked Questions ( FAQs ) , some changes had not been addressed. It was therefore considered that a revised Edition 4.1.0 should be published to incorporate all cumulative changes since Edition 4.0.0. The Hydrographic Services and Standards Committee ( HSSC ) endorsed the changes to Edition 4 .0.0 of S- 57 Appendix B.1, Annex A proposed by the E NCWG by HSSC Letter (see Reference B ) and tasked the HSSC Chair to submit the revision to the IHO Council for endorsement, under the arrangements that are now in force as a result of the ratification of the Protocol of Amendments to the Convention on the IHO; and following the establishment of the Council by the first session of the IHO Assembly (see Reference C - Decision No. 26) . At its 1 st meeting in October 201 7 , the IHO Council endorsed the revision and tasked the IHO Secretariat to circulate draft revision 4 .1.0 of S- 57 Appendix B.1, Annex A to IHO Member States , for their consideration and approval ( see Reference D – D ecision C-1/20 and A ction C-1/21 ). The proposed revision 4 .1.0 and a marked up “redline” version are now available on the IHO website at: www.iho.int > Standards & Publications > Download > Draft Publications Awaiting Approval by Member States ( English version only ) . Member States are requested to take into account the endorsement of the HSSC and the IHO Council and to consider the adoption of the proposed edition 4 .1 .0 of S-57 Appendix B.1, Annex A by providing their reply on the Voting Form in Annex A , at their earliest convenience and no later than 05 January 201 8 .
