WECDIS and AML

The future of electronic charts in warfare at sea
Concepts concerning WECDIS and AML (Additional Military Layers) to support warfare at sea have been developed for quite a few years - now they are being realised. It was more than five years ago that NATO developed ideas concerning how navigation could be made safer, whilst at the same time bundling and providing additional information. The problem was, and still is, that in addition to the data necessary for navigation there are lots of specialist charts. This results in the same information being published not just once but several times, by various publishers, and designed to fit the requirements of... (read more)

US Army IENCs and Hydrographic Database Technology

US Army IENCs and Hydrographic Database Technology In 2001, the US Army Corps of Engineers (USACE) began to produce Inland Electronic Navigational Charts (IENCs) for US waterways. A paper chart was made from IENC data by IIC, working with the Corps; now improved HPD technology has been used to further investigate this concept and its ramifications for multiple product consistency, currency and ease of production. An essential feature of any charting programme is continual maintenance and dissemination of consistent, updated and significant products. With recent advances in Hydrographic Product Database (HPD) technology it is now possible to link and merge... (read more)

Automated Depth Area Generation for Updating NOAA Nautical Charts

National Oceanic and Atmospheric Administration’s (NOAA’s) Marine Chart Division (MCD) is currently revising production efforts using an ‘ENC-first’ approach to provide seamless and tiled geographic coverage. Currently, ENC production workflows within MCD require cartographers to manually manipulate data in the Nautical Information System (NIS) to update navigation products. This MCD addressed this production bottleneck by developing a tool to derive depth area, contour and sounding vector data directly from gridded raster bathymetry surface data. Production of Electronic Navigational Charts (ENCs) Over the past decade, automation of data compilation procedures within NOAA’s Office of Coast Survey (OCS) and MCD (responsible for... (read more)

Mariners Need More Current Hydrographic Data

Hydro International Interviews Rear Admiral Christian Andreasen, NOAA (Ret.)
Almost 50 years in hydrography gives you insight and authority to talk about the field and the changes it has gone through in half a century. Rear Admiral Christian Andreasen talks about his career. He is certainly not somebody who only looks back, but is still looking into the future, sharing strong ideas about where hydrography will need to go: ‘Mariners do not understand why hydrographic offices are not more supportive. Finding ways of providing mariners with more current data is an issue.’ Since the 1960s, when you became a hydrographer up to the present, the means and techniques for... (read more)

The Electronic Chart

Book Review
The two most significant developments in navigation for many decades have been the introduction of global satellite navigation systems, such as GPS, and the electronic chart. In the case of GPS and similar systems, their background, use and advantages have been very apparent and it would be rare to find an average schoolboy now still unaware of the existence of GPS and it uses. The electronic chart has not been as fortunate. Since it's conception and on though the development and regulatory phases up to the point of implementation, the introduction of the electronic chart has been complicated and in... (read more)

We Visited for You

2nd International ECDIS Conference
A key objective of the 2nd International ECDIS Conference: ‘ECDIS Ð for Coastal and Ocean Navigation’, held in Singapore from 7th to 9th October, was to inform current and potential users of developments in the delivery of ECDIS. The three-day conference was co-organised by the Hydrographic Department of The Maritime and Port Authority of Singapore and the UKHO and attracted a wide range of delegates from thirty countries representing shipping companies, manufacturers, universities, training institutes and hydrographic offices. After the opening preliminaries, the Conference began with an informative, albeit sobering, keynote address by Admiral Sir Nigel Essenhigh (former UK Hydrographer... (read more)

4th Extraordinary International Hydrographic Conference

The 4th Extraordinary International Hydrographic Conference (EIHC), held in the Auditorium Rainier III in Monaco from 2 to 4 June, was followed on 5 June by World Hydrography Day. The Conference, chaired by captain Rachid Essoussi, head of the Hydrographic and Oceanographic Service of Tunisia, was attended by representatives from 53 of 80 Member States of the International Hydrographic Organization (IHO) and several other countries and international organisations with an interest in IHO activities.<P> The Conference was organised well by the Directing Committee of the International Hydrographic Bureau (IHB) and its staff. Opening addresses were given by admiral Maratos, who... (read more)

The Rocknes Casualty 2004

A Chartmaker’s Retrospect
The MV Rocknes (about 17,000 GRT (Gross Register Tons), draught approximately 10.5m, see Figure 1), en route from Eikefet, Norway to Emden, Germany, hit a shoal in Vatlestraumen, Norway on 19 January 2004. The vessel carried a pilot from the Norwegian Coastal Administration (NCA). Soon after the grounding the ship capsized with the loss of 18 crew. 12 crew were rescued. Norwegian Hydrographic Service (NHS) was blamed for not publishing its knowledge of a presumed new shoal in the Vatlestraumen. Three subsequent lawsuits were necessary to establish a credible explanation of the accident’s root causes. 10 years after the serious... (read more)

Reflecting on Twenty Years of Electronic Charts

Hydro INTERNATIONAL interviews Dr Fosco Bianchetti of C-Map
Dr Fosco Bianchetti is Chief Executive Officer of C-Map, which he founded in 1986. He has been an innovative force in the field of marine electronics and is a recognised pioneer in electronic cartographic products and systems. In 1984 he co-founded Navionics, Italy, and conceived the first commercially successful electronic chart system. Could you tell us a little about yourself, your background and career? I studied electronics and computing at Pisa University. Then, having done military service in the airforce, I managed some large telecommunication projects in Europe and the Middle East. But never having planned life in a big... (read more)

We Visisted for You

Industry / Stakeholders Workshop, IHB Monaco
For the fourth year in succession, the IHB (International Hydrographic Bureau) Directing Committee held a workshop from 16th to 17th June 2003. About fifty people attended, among whom hydrographic or navigational equipment manufacturers, data producers, academics, mariners, chart agents and representatives of Hydrographic offices or other national maritime organisations; all referred to as 'stakeholders'. Although one of the major subjects remained, as in previous years, ENC - or rather the lack of it - the actual goal of these gatherings, namely to establish a liaison mechanism between the 'industry' and the IHO, would seem to be coming closer. This year's... (read more)
