Electronic Navigational Charts(ENCs) are official nautical charts which are equivalent to paper charts with supplementary information. Although their main purpose is to be used for the safe navigation of ships, they also contain much information on coasts and seas which may be interesting to ordinary people. However, there is no easy way to access them because of their specialized data format, access method and visualization. This paper proposes m implementation of SVG for the access and services of ENCs. SVG(Scalable Vector Graphic) makes it possible to make use of Vector graphics for map services in basic internet browsing environment. Implementation of SVG for ENC applications by this research is free of special server side GIS mapping system and client side extra technology. The Implementation of SVG for ENC Applications can be summarized as follows: Firstly, SVG provides spatial information to possess searching engine to embody SVG map. Secondly SVG can provide high-quality vector map graphics and interactive facility without special Internet GIS system. It makes it possible to use services with very low cost. Thirdly, SVG information service targeting on maritime transportation can be used as template, so it can be used dynamically any other purpose such as traffic management and vessel monitoring. Many good characteristics of SVG in mapping at computer screen and reusability of SVG document provide new era of visualization of marine geographic information.

As the technical standard of hydrographic data was transferred from S-57 to S-101, a standard system was set up for producing the next generation ENCs but also various maritime safety information. ECDIS that display a S-57 ENC and include a navigation support function, should be developed considering new standard. S-10X data and e-Nav information can be used in this system. In this study, an implementation mechanism of S-100 standard was analyzed for design of navigation support system based on S-100. From the results, it was designed as loading module of S-10X data, display module of SENC, navigation supporting module. Also, this study considered a next generation ENC, a bathymetric grid data, an electronic nautical publication as an input information.

ENC(Electronic Navigational Chart) is an electronic chart that digitize nautical chart including all kinds of information of nautical chart. Mariners have difficulty reading information because of clutter problem if display scale of ECDIS is lower than compilation scale of ENCs. IHO made SCAMIN improvement model included in S-65 Standard to settle this ENC clutter problem. This SCAMIN model includes both simple restriction that should safety some requirement and share geographic information. and hard restriction that should overlap with area object such as depth area, land area, dredge area. It also apply SCAMIN step of sounding value according to importance of safety navigation. In this paper, we analyzed the restrictions for SCAMIN model of S-65 Standard, developed algorithm and application to apply theses restrictions reasonably and mechanically. Also we applied this algorithm and application to Korea ENCs and evaluated the result of performance.

IMO adopt the revision of SOLAS convention on requirement systems for ECDIS and considered an ECDIS as the major system for E-Navigation strategy on marine transportation safety and environment protection. ENC(Electronic Navigational Chart) as base map of ECDIS is considered as a principal information infrastructure that is essential for navigation tasks. But ENCs are not easy to utilize because they are encoded according to ISO/IEC 8211 file format, and ENCs is required to utilize in parts of Marine GIS and various marine application because they are used for navigational purpose mainly. Meanwhile Google earth is satellite map that Google company service, is utilized in all kinds of industry generally providing local information including satellite image, map, topography, 3D building information, etc. In this paper, we developed KML conversion technology for ENC application. details of development contents consist of ENC loading module and KML conversion module. Also, we applied this conversion technology to Korea ENC and evaluated the results.

Copyright infringement and data piracy are pervasive problems of digital era and Electronic Navigational Charts(ENC) are not free from these issues. Aside from the economic impact, the unofficial distribution of nautical information has sign띠cant safeη concerns. Therefore, official distributors of nautical information have sought appropriate methods to protect their data and to provide the mariner with a certificate of authenticity through the adoption of security schema. However, a plethora of different security schema provided by independent distributors markedly complicates the software development of Electronic Chart Display and Information Systems (ECDIS) manufacturers and makes it more difficult to achieve the goal of seamless world-wide electronic navigational database easily accessible to the mariner. A fundamental concern of IHO is that adoption of a single, centrally administered security scheme for all ENCs could improve the ease of use of ENCs and enhance safety of navigation. IHO have driven protection scheme as S-63, S-63x. NORI(National Oceanographic Research Institute) necessarily need protection scheme and supporting system for nautical information. This paper presents protection scheme for NORI and proposes support system for ENC protection.

Electronic Navigational Charts (ENCs) are digital charts which contain a great variety of data on coast and sea regions. Although they contain much information that ordinary people are interested in, there is no easy way to access because they are coded in the specialized data forma, and can be visualized by using specialized system. Therefore, supporting systems need to be developed for ordinary people to easily access ENCs. This paper proposes a framework for the ENC systems based on the Web. It relies on quite general standards such as Ceography Markup Language (GML) and Scalable Vector Graphics (SVG). In the framework, ENCs coded in S-57 format are first translated into GML to be stored in a database. Once the database is built, users can request to the database what they want. According to the user request, relevant data are retrieved, and then translated into SVG to be displayed on the Web browser. By using the framework, ordinary people may easily access coast and sea information contained in the ENCs. Furthermore, the framework may provide interoperability by virtue of XML-based standards such as GML and SVG, and efficiency by virtue of database. To validate the feasibility of proposed framework, a prototype system is developed and tested.

Electronic Navigational Charts (ENCs) are digital charts encoded in S-57 format, which contain navigational informations such as coastlines, depth areas, and nautical marks. Although they have been successfully used for the safe navigation of ships, they have limited usages and applications because of their specialized data format and access systems. To cope with such drawbacks, S-57 ENCs need to be transformed into more generalized format such as Geography Markup Language (GML). The transformed GML ENCs can be kept in a database for efficiency, and can be accessed through Internet for usability. This paper proposes a new method for transforming and managing ENCs with XML database. S-57 ENCs are lust transformed into GML format, and then stored in a XML database. On the database, users can query for their needs. To validate the feasibility of the proposed method, we developed a protype system, and then conducted several test runs. The system can provide users with easy access to the marine information contained in ENCs. It also provides compatibility and efficiency by virtue of GML and XML database, respectively.
