S-126Physical Environment Test Data Set

Current test data set
• Environmental features found in nautical publications– E.g. marine topography; submarine springs; volcanic; currents; tides;
met-ocean;
• Based on Indian Ocean and Jussland• First presented at SNPWG17• No work since SNPWG18 (version 2)

Current questions
• How will environmental features in S-126 relate to features in other product specifications?– S-101– topo, currents, tides, ice, met-ocean
• Text vs graphical information • Questions listed at SNPWG18

SNPWG18 questions• Is it possible to use the term ‘season’ in generalised descriptions of
phenomena. (eg. Monsoon season)?• Is it permissible to use seasons instead of specific months (eg. summer,
winter etc)?• Para 1.2.1 – Do we want this kind of information (Deeps) in S-126?• Do we need/want the ability to use links to other specialist documents where
it is not appropriate to provide a full explanation of phenomena (eg. Mariner’s Handbook etc)?
• Do we want links to specialist graphics (wind/temperature/swell/MSL etc)?• Do we want to include regional variants (external to region being described)
of the same basic phenomenon (Hurricane/Typhoon/Cyclone)?• Are there any further phenomena/data types that need to be included?• We need to decide on whether the terrestrial environment data set needs to
contain man-made structures such as towns/built up areas/water collection.

Conclusions
There are risks that:• work on S-126 is too focused on trying to replicated
information in existing publications rather than an appreciation of what S-126 will aim to achieve in combination with other S-100 products
• S-126 development is based on what can be done, rather than what is required by users.

Recommendations
• Requirements for S-126 need to be clearly defined before further work can be meaningfully progressed.
• Greater engagement with end users.• Closer liaison with the S-100WG.

Actions Required of NIPWG
• Endorse recommended approach• Define purpose of S-126• Agree the priority for this work
