Electronic Chart  Display And Information System (ECDIS) adalah suatu alat navigasi berupa peta elektronik sesuai persyaratan peta terbaru konvensi SOLAS 1974 V/20 yang dapat diintegrasikan dengan ala-alat navigasi lainnya sehingga diperoleh posisi dan informasi navigasi lain untuk para mualim melakukan perencanaan pelayaran serta monitoring rute pelayaran. Tujuan dari penelitian ini adalah untuk meningkatkan pengetahuan para Mualim dalam penggunaan ECDIS agar mencapai keselamatan dalam berlayar. Metode yang digunakan dalam penelitian ini adalah metode kualitatif yang mendeskripsikan melalui kata-kata dan bahasa dalam menjelaskan masalah atau fenomena yang  diteliti. Untuk menjabarkan masalah digunakan jenis penelitian deskriptif yaitu dengan mendeskripsikan suatu gejala, peristiwa dan kejadian yang terjadi. Pengumpulan data dilakukan melalui wawancara, dan observasi dalam melakukan penelitian, studi pustaka dan studi dokumentasi. Hasil penelitian ini menunjukkan bahwa para mualim belum maksimal dalam penggunaan ECDIS sehingga diperlukan peningkatan pemahaman dan pengetahuan dalam menggunakan ECDIS agar keselamatan bisa diutamakan saat berlayar.

Taking Action

In this paper, authors suggest an improvement in the electronic chart display and information system handling. Electronic nautical charts provide significant benefits to maritime navigation as a real time navigation system and all updates are important. This paper analyses the electronic chart use experiences on board ships. A questionnaire and survey were used so as to ascertain and corroborate the existing problems with corrections and maintenance of electronic charts on ships, and reliability of the systems was calculated. The survey results have shown that ship’s officers had serious problems with ECDIS systems which were difficult to solve during ship’s operation. A survey was done which showed that a significant percentage of the surveyed bridge officers and captains had problems with ECDIS system operation, such as operation stoppage due to different reasons. They did not always report failures of these systems while having continued to operate ECDIS. The reliability of those systems was also calculated and it resulted 0.916 or 91.6%. Compared to results of previous similar researches done by other scientists, the results of this research show an improvement in the ECDIS handling. It was concluded that a proper action was needed toward finding the solution to the future chart corrections procedure through remote monitoring and maintenance. The study results emphasized that taking action was necessary in the interest of safety protection on ships, with particular attention to be paid to better safety of navigation, of life, and of potential environmental pollution due to this type of information system failures. The results obtained by this study represent a good starting point for future researches in the field.

In this paper, equations are established to solve problems of Rhumb Line Sailing (RLS) on an oblate spheroid. Solutions are provided for both the inverse problem and the direct problem, thereby providing a complete solution to RLS. Development of these solutions was achieved in part by means of computer based symbolic algebra. The inverse solution described attains a high degree of accuracy for distance and azimuth. The direct solution has been obtained from a solution for latitude in terms of distance derived with the introduction of an inverse series expansion of meridian arc-length via the rectifying latitude. Also, a series to determine latitude at any longitude has been derived via the conformal latitude. This was achieved through application of Hermite's Interpolation Scheme or the Lagrange Inversion Theorem. Numerical examples show that the algorithms are very accurate and that the differences between original data and recovered data after applying the inverse or direct solution of RLS to recover the data calculated by the direct or inverse solution are very small. It reveals that the algorithms provided here are suitable for programming implementation and can be applied in the areas of maritime routing and cartographical computation in Graphical Information System (GIS) and Electronic Chart Display and Information System (ECDIS) environments.

Great Sense

There is a great sense of movement and progress in navigation today. The excitement lies in the ability to do things which were not possible with traditional media or at best were difficult and time-consuming to achieve. So this paper is not about the desirability nor the timescale of the ECDIS (Electronic Chart and Display Information System) replacing paper charts for primary navigation. It is about the flexibility and creative power opened up by new technology.

Automatic route design will help to develop electronic chart intelligence, hence to improve safety, economy and reliability of the route. In the paper rasterizing charts are used to expressed the navigation environment of the ship and the modified A* algorithm is used to compute the near optimum trajectory of a ship in given environment based on electronic chart dispiay and information system (ECDIS). By tracing Safety contours, computing obstacle areas and taking into account certain boundaries of the manoeuvring region, the problem of avoiding collisions at sea was reduced to optimization task with static constrains. Simulation using MATLAB is conducted to verify the proposed ship path planning method. The good results show the promise of this method for ship at sea.

Ocean Environment

With rapid development of the geographic information system technique, the electronic chart has come into being and is more and more mature. The electronic chart can provide the accurate and detailed information about the ocean environment, including the depth of water, situation of the seabed, distance from the shore, position, orientation and velocity of the ship, and other useful information. This paper first gives some introduction about the electronic chart. After analyzing the characteristics of the electronic chart, the application of the electronic chart in ocean navigation is provided. Finally the existing problem of the electronic chart and its future development trend are also discussed.

Data Files

It is probable that Congress will require oceangoing ships in US ports to use Differential GPS (DGPS) and electronic charts once DGPS is available on all coasts of the US, which is currently scheduled for completion by the end of 1996. The type of electronic chart currently envisaged, the Electronic Chart Display and Information System (ECDIS) under development by the IMO & IHO, is unsuitable for those ports which are entered through long dredged channels – a category that includes Houston, Gramercy and New Orleans, the three ports which handled the most foreign tonnage in 1991. A different type of electronic chart has been in daily use in such channels, with microwave positioning, since 1984; the combination of DGPS with such a software package has been called an Electronic Navigation System (ENS) and differs from ECDIS in that the ENS is designed to supplement the published chart, not replace it. The paper suggests that the utility of ECDIS would be enhanced if its specifications were modified to allow the entry of the data files used by the ENS, thus giving ECDIS a similar capability for blind navigation in confined waters. Standardization of the current data format would also permit alternative versions of ENS to be developed.

New System

The AN/SSN-6 Navigation Sensor System Interface (NAVSSI) Project is a new system being designed with two primary objectives; to serve as the central distribution computer for navigation data to shipboard combat/weapon systems and to serve as the electronic chart display and information system (ECDIS). The NAVSSI will operate the digital nautical chart (DNC) database being developed by the Defense Mapping Agency (DMA). Our goal is for the digital nautical chart to replace the paper chart as a legal means of ownship navigation plotting. This paper will introduce the project and will primarily explore the use of digital nautical charts for ownship navigation with NAVSSI.
