There are three new elements of hydrographic importance contained in Chapter V of SOLAS which will increase safety at sea; the provision of hydrographic services, the definition of nautical charts and...
The International Hydrographic Organisation (IHO) and the International Maritime Organisation (IMO) are co-operating very closely to take appropriate action for the mandatory carriage of ECDIS to incr...

The existence of Web-based Geographic Information System (Web-based GIS) will enable the Hydrographic Information System to integrate all the activities of a Hydrographic Office on a single integrated...
The IMO is considering a phased programme to make the carriage of ECDIS compulsory. This could mean that certain vessels be required to carry ECDIS from as early as 2008. In my view, this is the key t...
My colleague Peter Johnson presented a paper at this year’s Canadian Hydrographic Conference explaining how Australia is implementing Zones of Confidence in its charts. The Zones of Confidence (ZOC)...
July 2002 signalled a significant milestone in the long, tortuous life of ECDIS. It was the month that ECDIS was formally recognised (and specifically mentioned) in SOLAS Chapter V. It should have bee...
A number of contributors to this column have discussed the benefits that information technologies bring to the conduct of hydrographic surveys and the production of nautical charts. Likewise, these te...
Twenty-cm accuracy GPS-based systems are already available offshore in many parts of the world, and progress is being made towards centimeter-accuracy systems. Can we find real benefits from this incr...
As most readers will know, the United Nations Convention on the Law of the Sea (UNCLOS) stipulates that information on the limits of the continental shelf beyond 200 nautical miles from the baselines ...
Hydrographic surveys may be specified to meet many different requirements. For example, a survey may be for nautical charting to re-survey a shipping channel where under-keel clearance is critical, or...
The link between the development of a State and its trade was identified centuries ago. In spite of the efforts of countless projects, the awareness of the importance of charts and maritime safety inf...
In April this year I represented the South West Pacific Hydrographic Commission (SWPHC) at the eleventh meeting of the Pacific Islands Maritime Association and the first Meeting of Pacific Minsters of...
The availability of various sensors and sophisticated technology providing digital data means that today’s hydrographers must attune to the idea that the final products should be available in a hydr...
