MEMBER STATES’ RESPONSES TO IHO CL 27/2020 AND COMMENTS
FROM THE WORKING GROUPS’ and HYDROGRAPHIC SURVEYS PROJECT TEAM’s
CHAIRS, HSSC CHAIR/SECRETARIAT
S-44, Ed. 6.0.0 IHO Standards for Hydrographic Surveys
IRAN (ISLAMIC REPUBLIC OF) (Vote = YES)
It should be noted that Table 1 and Table 2 in new version are considerably more complicated
than previous versions.
Comments by the HSPT Chair and HSSC Chair/Secretariat:
The HSPT Chair/HSSC Chair/Secretariat thank Iran for their comment. This appreciation is
noted and will be discussed at HSSC-12. The possibility of having a couple of virtual workshops
in the near future to accompany the entry-into-force of this new Edition may be considered.
PERU (Vote = YES)
(Original in Spanish) We approve the 6th Edition version 2.0.1 and we are sure that, greater
orientation and detail in the specifications, will facilitate our work.
Comments by the HSPT Chair and HSSC Chair/Secretariat:
The HSPT Chair/HSSC Chair/Secretariat thank Peru for their comment.
PHILIPPINES (Vote = YES)
We support for the improvement of our nautical charting and hydrographic survey system.
Comments by the HSPT Chair and HSSC Chair/Secretariat:
The HSPT Chair/HSSC Chair/Secretariat thank Philippines for their comments.
URUGUAY (Vote = YES)
Uruguay does endorse the draft of edition 6.0.0 of S-44. It is highly appreciated the Matrix
introduction in this version of the standard as a reference table for determining quality of
bathymetric surveys.
Regarding with general contents of the draft, we noticed a slight issue on page 35/46, when
mentioned "Water Flow" class, its associated capital letter is improperly indicated as "T"
instead "W" which is employed in the rest of the document. In the same way, for that specific
example, the acronyms are incorrectly noted as "Ta1", "Ta3" and "Tb5".
Comments by the HSPT Chair and HSSC Chair/Secretariat:
The HSPT Chair/HSSC Chair/Secretariat thank Uruguay for these comments and relevant
observations. Corrections have been applied in the final version accordingly.
Mariners’ Guide to Accuracy of Depth Information in
S-67 Ed. 1.0.0
Electronic Navigational Charts (ENC)
FRANCE (Vote = YES)
See comment offered by France in Annex A to IHO CL 27/2020 (given below for ease
convenience).
On the occasion of a future revision, the document could usefully be supplemented by
extending the subject of CATZOC beyond ENCs, which is more and more often present on
paper maps in the form of a diagram. The elements of Annex B could come in redundancy
from the paper "Information on ENC Generalization, Over-Scaling and Safety Checking
Functions in ECDIS" which will be presented at HSSC12 at the end of 2020.
Comments by the DQWG Chair and HSSC Chair/Secretariat:
The DQWG Chair/HSSC Chair/Secretariat thank France for this reminder. As indicated in
Reference A, Doc. HSSC12-05.2B “"Information on ENC Generalization, Over-Scaling and
Safety Checking Functions in ECDIS" is planned to be discussed at HSSC-12.
PERU (Vote = YES)
(Original in Spanish) We approved Edition 1 version 2 and understand that navigators must
know which parts of the bathymetry in an ENC are accurate and reliable, and which parts
require caution.
Comments by the DQWG Chair and HSSC Chair/Secretariat:
The DQWG Chair/HSSC Chair/Secretariat thank Peru for their comments.
PHILIPPINES (Vote = YES)
We support for the improvement of our nautical charting and hydrographic survey system.
Comments by the DQWG Chair and HSSC Chair/Secretariat:
The DQWG Chair/HSSC Chair/Secretariat thank Philippines for their comments.
URUGUAY (Vote = YES)
SOHMA considers this new Standard as a very valuable publication for the international
community. Also, it will be adopted by Cartography team of SOHMA.
The standard will contribute to ease the training process for all the compilers due to the
gathered information contained within it. However, it would be good to have the possibility to
get a Spanish translation soon. SOHMA would like to collaborate with this task if necessary.
Comments by the DQWG Chair and HSSC Chair/Secretariat:
The DQWG Chair/HSSC Chair/Secretariat thank Uruguay for their comments and offer. The
translation of IHO Standards into different languages is a permanent issue periodically
addressed at HSSC meetings. This request is duly acknowledged and it is expected that
Spanish-speaking Members will agree to combine their efforts to produce a Spanish
translation.
S-49, Ed. 2.1.0 Mariners Routing Guides
PERU (Vote = YES)
(Original in Spanish) We appreciate as important the coordination made with IMO for the
characterization of the international charts in view that they will be used in international
navigation.
Comments by the NIPWG Chair and HSSC Chair/Secretariat:
The NIPWG Chair/HSSC Chair/Secretariat thank Peru for their comments.
PHILIPPINES (Vote = YES)
We support for the improvement of our nautical charting and hydrographic survey system.
