Official Development Assistance(ODA) Project is initiated to assist a developing country economically and to promote its welfare. Support on training and information system development are the primary elements in the maritime safety field. The maritime safety information system(MSIS) of ODA projects deals with maritime safety information of developing nations and ensures an inter-operability between other systems. Therefore, it is required to develop MSIS based on the Universal Hydrographic Data Model(UHDM) of International Hydrographic Organization(IHO). In this paper, we have analyzed the current status and operational process of UHDM established by IHO. Oil spill response system was selected as an example of MSIS project and, also, considered the application results to the maritime safety field of UHDM.

해상에서의 데이터는 디지털 수로데이터 교환 표준인 국제수로기구(IHO, International Hydrographic Organization)의 S-57을 기반으로 제작된다. 그러나 S-57은 지리정보 외의 정보를 표현하는데 한계를 나타내었다. S-57의 한계를 극복하기 위하여 다양한 해양데이터를 활용할 수 있는 시스템 체계로 수로 데이터를 위한 데이터 모델과 규격을 정의하는 S-100을 제정하였다. S-100을 기반으로 하여 수로데이터를 위한 표준으로 S-101을 제정하고 있으며, 데이터 검색 및 활용을 위한 메타데이터도 포함하여 구성하였다. S-101의 개발에 따라 S-57전자해도를 S-101전자해도로 변환이 요구되고 있으며, 이와 함께 메타데이터에 대한 변환도 필요하다. 본 논문에서는 S-57의 메타데이터 요소와 S-101의 메타데이터 요소를 비교 분석하여 메타데이터 변환모델을 제시하였다.

International Hydrographic Organization(IHO) adopted standard S-100 as the international standard Geographic Information System(GIS) that can be generally used in the maritime sector. Accordingly, the next-generation system to support navigation information based on GIS standard technology has being developed. AR based navigation information system that supported navigation by overlapping navigation information on the CCTV image has currently being developed. In this study, we considered the application of a transparent display as a method to support efficiently this system. When a transparent display applied, the image distortion caused by using a wide-angle lens for parallax secure, and the disc s, and demonstrated the applicability of the technology by developing a prototype.

Several studies have been performed globally on the construction of integrated systems that are available for the integrated use of 3D geographic information on terrain and oceans. Research on 3D geographic modeling is also facilitated by the application of Lidar surveying, which enables the highly accurate realization of 3D geographic information for a wide area of land. In addition, a few marine research organizations have been conducting investigations and surveying diverse ocean information for building and applying MGIS(Marine Geographic Information System). However, the construction of integrated geographic information systems for both terrain and oceans has certain limitations resulting from the inconsistency in reference systems and datum levels between two data. Therefore, in this investigation, integrated geospatial information has been realized by using a combined topographical map, after matching the reference systems and datum levels by integration of airborne Lidar data and multi-beam echo sounder data. To verify the accuracy of the integrated geospatial information data, ten randomly selected samples from study areas were selected and analyzed. The results show that the 10 analyzed data samples have an RMSE of 0.46m, which meets the IHO standard(0.5m) for depth accuracy of hydrographic surveys.

With recent technological advances in the shipbuilding industry, vessels have been improved in size and performance. As a result, an accident such as grounding, caused by a single ship-to-ship collision, could lead to a large-scale maritime disaster. Considering the seriousness of the situation, the international community has been consistently updating the standards for Electronic Navigational Chart(ENC) to improve the maritime safety. S-57, the existing ENC standard governed by the International Hydrographic Organization(IHO), includes standards for generating conventional binary-type ENC data sets. The S-57 standard, however, has not been updated since the release of Version 3.1 in December 2000. Since then, the standard has failed to reflect technological development regarding maritime spacial information, which has been consistently improving. In an effort to address this concern, the IHO designated S-100, i.e., the next-generation ENC production standard. S-100 differs from S-57 in data exchange type. Contrary to the conventional ENC standards, which use binary-type data, S-10X, based on the next-generation ENC standards, uses ENC data composed of Feature Catalogue, Portrayal Catalogue, and GML. Considering this fact, it is necessary to update S-58, the ENC validation check standard, or designate a new standard for ENC validation checks. This study is developed own software to implement validation checks for new types of data, and identified improvement points based on the test results.

This paper deals with a possible contribution to international relations and affairs by the discipline of geography and raises the necessity of a new field in geography that would study relations between nations. The proposed change of the name 'East Sea' is used as a case study in promoting international standardization. Two major international organizations oversee the international standardization of geographical names. One is the UN Conferences of the Standardization of the Geographical Names which work in association with the UN Group of Experts on Geographical Names, and the other is the International Hydrographic Organization. These two organizations have in the past passed all the relevant resolutions pertaining to geographical names. From recent developments on the Korean Peninsula, however, it has become evident that international disputes on place names sometimes require a long process of consultation with the relevant parties. Efforts being made to restore the historically appropriate name of 'East Sea' as opposed to the 'Sea of Japan' have only now begun to diffuse in many areas. It would be appropriate if geographers could develop a new area of 'Geography of International Relations' that deals with WTO, oceans, environment and climatic issues, FAT, as well as territories and boundaries. Furthermore, it would improve the quality of discourse if geographers participated more in the decision-making processes in international affairs.

A nautical chart is an essential material not only for the safety of navigation at sea, but also for the research and understanding of the ocean. Paper nautical harts have been used for navigational purposes for several hundreds years, but it was show that paper nautical charts have certain limitations, because the speed of ships has increased dramatically, and Global Positioning Systems (GPS) are now available at sea. Thus, the development of digital charts has been conducted by a number of countries. As a result, the International Hydrographic Organization (IHO) has developed a standard format, Special Publication No. 57 (S-57), as a guideline for the production of electronic navigational charts (ENC). Even though ENCs are a state-of-the-art navigational tool because they are produced on the basis of Geographical Information System (GIS) technology, they can be utilized for various purposes. in this paper, the usage of paper nautical charts, ENCs, and digital charts is reviewed. Also, the various application system that make use of electronic navigational harts and digital charts, as a basic geographical source of information, will be examined on the basis of GIS.
