This paper describes a method for making 3D marine environmental database of ship handling simulator by using electronic nautical chart data. While developing simulator system, we had to digitize the nautical paper chart in order to obtain the basic data including coastline, navigational aids and so on. In our method, we can get easily exact data necessary to make the database of visual presentation system from electronic nautical chart data that is coded according to S-57 transfer standard of IHO.

e-Navigation의 도입에 따라, 선박 교통 정보의 대한 공유의 필요성이 높아지고 있다. 특히 선박 교통 관제 시스템인 VTS(Vessel Traffic Service) 시스템에서도 효율적인 관제와 e-Navigation에 도입에 따라 VTS 시스템간 데이터 공유가 필요한 실정이다. 이에 따라 국제항로표지협회(IALA, International Association of Marine Aids to Navigation and Lighthouse Authorities)에서는 VTS간 데이터 교환을 위한 표준 포맷인 IVEF(Inter VTS Exchange Format)을 제정하였다. IVEF는 XML 형태로 다양한 플랫폼에서 활용가능하다. 본 논문에서는 VTS 시스템 간 데이터 교환을 위한 표준 포맷인 IVEF를 이용하여 VTS 시스템 간 데이터 공유를 위한 웹 서비스에 대해 설계하고, 이를 응용하는 방법에 대해서 설명한다.

Recently, the marine traffics have been increased along with enlargement of overseas commerce. Increasing the marine traffic may make higher the risk of marine accidents. Especially, the rate of accidents on costal area are more frequently. As if the marine safety information can be afforded to vessel and shore, the accident rate would be down. AIS AtoN is the navigational safety support device which is subject to functional requirements of IALA and technical standards of ITU. In this paper, we extend and implement the user-defined specification of AIS AtoN with message 21 for AIS basic information, messsage 6 for status report and message 12/14 for safety management.

In order to provide a safe and secure electronic navigational chart information services, AIS information, information on aids to navigation, maritime safety information, weather information, information on a variety of birds such as the data fused S-100 standards-based e-Navigation system should be established. S-101 ENC implement Rendering Engine analyzes the Drawing Instruction set generated by Portrayal Engine of the S-100 General Portrayal Model for is a job to be followed to establish the e-Navigation System to implement the S-101 ENC Should be. In this paper, we analyze the Drawing Instruction of the existing S-57 ENC and S-101 ENC is the basis for the implementation of the S-101 ENC.

Dual LED lantern, which is composed of two light sources in one lantern, can be utilized as an auxiliary light source when the main light source is in trouble. Nevertheless, there are no way to obtain status information of the system and control the light source if the current domestic standard protocol is applied, since the standards for dual LED lantern are not defined yet. Regarding to this problem, we suggested expanded lantern protocol for management system of dual LED lantern based on current domestic standard. Also, we confirmed the normal operation of dual LED lantern after implementing suggested protocol on the developed management system. Control system suggested and implemented in this study is tested not only its function of controlling and acquiring the operating status of dual LED lantern, but also its capability to utilize as a control system of currently used LED lanterns.

The IVEF service is the draft standard designed for exchange of information on sea traffic between the vessel traffic systems and between the vessels. Standardization of this service is under way as a part of the next-generation navigation system, called e-Navigation. The International Association of Lighthouse Authorities (IALA) suggests, on its recommendation V-145, the IVEF service model and the protocol for provisioning of this service. But the detailed configuration of this service must be designed by the users. This study suggests, based on the basic service model and protocol provided in the recommendation V-145, the implementation of the J-VTS middleware which will facilitate exchange of information on sea traffic. The J-VTS middleware consists of various components for providing the IVEF service and for processing the IVEF message protocols. The vessel traffic systems and the vessels corresponding to upper-layer applications may use the IVEF service with the functions provided by the J-VTS middleware, and the services are designed to be accessed according to the security level of users.

The International Association Marine Aids to Navigation and Lighthouse Authorities (IALA) proposed guidelines for VTS manual operation in 2016 for safe and efficient operation of ship. The Korea Coast Guard (KCG) established and operated 19 VTS centers in ports and coastal waters across the country by 2022 based on the IALA VTS manual and VTS operator's education and training guidelines. In addition, IALA proposed the Inter-VTS Exchange Format (IVEF) Service recommendation (V-145), a standard for data exchange between VTS, in 2011 for efficient e-Navigation system services and safe and efficient VTS service support by VTS authorities. The IVEF service in a common framework for ship information exchange, and it presents seven basic IVEF service (BISs) models. VTS service providers can provide safer and more efficient VTS services by sharing VTS information on joint area using IVEF standards. Based on the BIS data, interaction, and interfacing models, this paper introduced the development of the cloud-based VTS integration services performed by the KCG and the results of the VTS integration platform test-bed for IVEF service implementation. In addition, the results of establishing a cloud VTS integrated platform test-bed for the implementation of IVEF service and implementing the main functions of IVEF service were presented.
