Dear Hydrographer,
1. IHO Publication S-11 Part A - Guidance for the preparation and maintenance of International
Chart Schemes was originally published in 2005 (see Reference A). Besides updating its annexes on
printer nations (S-11 Part A - Annex A) and formats (S-11 Part A - Annex B), the only significant
change was the addition of an Annex C containing the Terms of Reference for International Charting
Coordination Working Groups (ICCWG) in 2010 (see Reference B). The current edition 2.0.5 was
adopted in 2012 (see Reference C).
2. In 2009, the Hydrographic Services and Standards Committee (HSSC) tasked the then Chart
Standardization and Paper Chart Working Group (CSPCWG), now the Nautical Cartography Working
Group (NCWG), to extend the scope of S-11 Part A in order to incorporate guidelines for the preparation
and maintenance of small and medium scale ENC schemes.
3. A draft text prepared in liaison with the World-wide ENC Database WG (WENDWG), the North
Sea ENC Harmonization Working Group and the INT Chart Coordinators was submitted to the 7th
meeting of the HSSC (HSSC-7) in November 2015. The draft text proposed combining the guidance
related to INT chart schemes and ENC schemes in a single document. Taking into account the
comments received, the HSSC instructed the NCWG to develop a separate section on ENC schemes
and to align the publication with the modernized S-11 Part B - International Chart Web-Catalogue and
associated on-line web based services which was presented at HSSC-7 and then announced in Reference
D.
4. Accordingly, the NCWG submitted a new draft text which was considered by the HSSC at its 8th
meeting (Reference E). The HSSC endorsed the proposed text and agreed to move the Annexes A and
B to S-11 Part B, and to publish separate English and French versions of S-11 Part A rather than a
bilingual document. The NCWG was tasked to finalize the proposed new Edition 3.0.0 and forward it
to the IHO Secretariat for circulation to IHO Member States, for their consideration and approval (action
HSSC8/35).
Mapping our Seas, Oceans and Waterways - more important than ever
5. As endorsed by the HSSC, the final proposed Edition 3.0.0 is structured as follows:
• Preface (revised from Edition 2.0.5);
• Section 100: Guidance for the preparation and maintenance of International (INT) Chart
Schemes (formerly the main part of S-11 Part A, revised from Edition 2.0.5);
• Section 200: Guidance for the preparation and maintenance of ENC Schemes (new text);
• Annex I: Terms of Reference for International Charting Coordination Working Groups
(ICCWG) (formerly Annex C of S-11 Part A, revised from Edition 2.0.5).
6. The publication has been reformatted from an English/French bilingual text to separate English
and French versions.
7. The information contained in S-11 Part A Edition 2.0.5, Annex A - Potential Printer Nations and
Annex B - Dimensions of Formats Used and Use of A0 Paper, can now be extracted from S-11 Part B
- International Chart Web Catalogue. These annexes have therefore been removed from S-11 Part A.
8. The final proposed Edition 3.0.0 and a marked up “redline” version, in English and in French,
are now available on the IHO website at: www.iho.int > Standards & Publications > Draft Publications
Awaiting Approval by Member States.
9. Member States are requested to take into account the endorsement of the HSSC and to consider
the adoption of Edition 3.0.0 of S-11 Part A by providing their reply on the Voting Form, provided in
Annex A, at their earliest convenience and no later than 15 April 2017.
On behalf of the Secretary-General
Yours sincerely,
