e-Navigation and Electronic Charting: Implications for Hydrographic Community
e-Navigation is a recent IMO initiative that aims to integrate existing/new shipboard and shore-based navigational tools into an âall embracingâ system. Defined as: â... the harmonised collection, integration, exchange, presentation and analysis of maritime information onboard and ashore by electronic means to enhance berth to berth navigation and related services, for safety and security at sea and protection of the marine environmentâ the goal of e-Navigation is to provide an infrastructure that will enable seamless information transfer onboard ship, between ships, ship-to-shore, and between shore authorities. Core elements include high-integrity electronic positioning, electronic navigational charts (ENCs) and improved system functionality towards reducing human error. In particular, this means actively engaging the mariner in the process of navigation while preventing distraction and overburdening. There are two main challenges in going from concept to implementation. 1) Ensuring the availability of all components of the system and using them effectively in order to simplify the display of crucial navigation-related information. 2) Incorporating new technologies in a structured way, while ensuring that their use is compliant with the existing navigational communication technologies and services. To date, the primary focus of IHO Member States has been to complete ENC coverage for major shipping routes. However, e-Navigation has other implications for the hydrographic community, including: 1) Use of AIS binary messages 2) Standards for Displaying e-Navigation Information 3) Guiding Principles for e-Navigation-related Informatio

ECDIS Development Laboratory and Navigation Technology Demonstration Center
The U.S. Navy is undergoing a major transition from traditional, paper chart navigation to computer-based electronic charting. The Chief of Naval Operations (CNO) has mandated that all Navy ships will navigate strictly through electronic means by FY07. However, due to some recent groundings, the Navy is now striving to accelerate the full implementation of electronic navigation by FY04. The Naval Oceanographic Office (NAVOCEANO) is making a concerted effort to support this transition with upgrades to state-of-the-art survey ships, instrumentation, and data processing equipment. NAVOCEANO is increasing its capability to rapidly collect and process hydrographic survey data, and to quickly produce new electronic navigational charts in co-production with MMA. In addition to ensuring safe navigation, these new products will include tactical digital overlays for bafflespace awareness. At NAVOCEANO, a new program is under development to expand these capabilities in a joint effort with University of Southern Mississippi\u27s new Hydrographic Sciences Research Program. In September 2001, an ECDIS Development Laboratory and Navigation Technology Demonstration Center will be established. This facility will conduct quality assurance (QA) and test and evaluation @&E) of electronic chart products from NAVOCEANO and other hydrographidoceanographic data providers. This facility will also assist Navy ship personnel in gaining a greater understanding of electronic charting, as well as increased technical proficiency in properly using these systems to safely navigate - particularly in the shallow littoral areas of the world. The ECDIS Development Laboratory is envisioned to become an information clearinghouse and demonstration center on electronic charting technological development. In addition to explaining the range of currently available government data products and services, The Navigation Technology Demonstration Center will showcase the use of electronic charts and its capability when used to avoid groundings and collisions at sea.

The Center will have commercial-off-the-shelf ECDIS and other electronic chartbased systems. A major focus will be to provide a better appreciation of the limitations electronic chart data produced by both the government and private sector that are derived from century-old hydrographic source data. Another important aspect will be to explain the capability and limitations of using very precise electronic navigation positioning systems (e.g., GPS and Differential GPS) with electronic charting systems. The Navigation Technology Center will also demonstrate the use of tactical digital overlays to provide naval vessels with critical military information that contributes to both safe navigation and increased warfrghting mission capability
S-100 Overlays: A Brave New World?
Marine Information Overlay (MIO) is a generic term used to describe chart and navigation related information that supplement the content that is already contained in an ENC. This includes both static and dynamic information such as tide/water level, current flow, meteorological, oceanographic, and environmental protection. With the advent of S-100 and S-101, there is increased interest in providing a wide variety of ânewâ overlay information. This paper provides a brief history of S-57 MIOs. Examples of navigational and non-navigation MIOs are given in terms of how currently used, by who, and for what purpose. Recommendations are provided for making a transition from S-57 MIOs to S-100 overlays that can be used with the âNext Generationâ ENC. More specifically, what has been proposed, how should they work, who will provide, and some future challenges/opportunities related to implementation

New Standards for Providing Meteorological and Hydrographic Information via AIS Application-specific Messages
AIS Application-specific messages transmitted in binary format will be increasingly used to digitally communicate maritime safety/security information between participating vessels and shore stations. This includes time-sensitive meteorological and hydrographic information that is critical for safe vessel transits and efficient ports/waterways management. IMO recently completed a new Safety-of-Navigation Circular (SN/Circ.) that includes a number of meteorologi-cal and hydrographic message applications and data parameters. In conjunction with the development of a new SN/Circ., IMO will establish an International Application (IA) Register for AIS Application-Specific Messages. IALA plans to establish a similar register for regional appli-cations. While there are no specific standards for the presentation/display of AIS application-specific messages on shipborne or shore-based systems, IMO issued guidance that includes specific mention of conforming to the e-Navigation concept of operation. For both IHO S-57 and S-100-related data dealing with dynamic met/hydro information, it is recommended that IHO uses the same data content fields and parameters that are defined in the new IMO SN/Circ. on AIS Application-specific Messages
The Role of Trust and Interaction in GPS Related Accidents: A Human Factors Safety Assessment of the Global Positioning System (GPS)
The Global Positioning System (GPS) uses a network of orbiting and geostationary satellites to calculate the position of a receiver over time. This technology has revolutionised a wide range of safety-critical industries and leisure applications ranging from commercial fisheries through to mountain running. These systems provide diverse benefits; supplementing the users existing navigation skills and reducing the uncertainty that often characterises many route planning tasks. GPS applications can also help to reduce workload by automating tasks that would otherwise require finite cognitive and perceptual resources. However, the operation of these systems has been identified as a contributory factor in a range of recent accidents. Users often come to rely on GPS applications and, therefore, fail to notice when they develop faults or when errors occur in the other systems that use the data from these systems. Further accidents can stem from the âover confidenceâ that arises when users assume automated warnings will be issued when they stray from an intended route. Unless greater attention is paid to the human factors of GPS applications then there is a danger that we will see an increasing number of these failures as positioning technologies are integrated into increasing numbers of application
