최근 산업사회의 발전과 더불어 세계 각국의 교역이 늘어나고 바다에 의한 경제 활동이 증대되면서 해양에 대한 가치는 더욱더 중요시되고 있다. 따라서 모든 해양국들은 자국의 수역을 좀 더 많이 확보하기 위해 인접국들과 첨예한 이해관계를 가지고 있는 상황이며 분쟁이 끊이지 않고 있는 실정이다. 본 연구에서는 국가간 해양영토에 관한 분쟁을 해결할 수 있는 영해기점의 정확도를 향상시키기 위한 영해기점 재 계산 방법에 대해 연구하였다.

As the depletion of land resources, the attention about marine resources has been focused on. Neighboring countries such as Japan and China to expand their marine territory invest more governmental money. The exact territorial sea baselines can be the scientific data which cad resolve the dispute between the neighboring countries. So, those territorial sea baselines should be maintained systematically and continuously. Because territorial sea baselines surveyed 10 years ago without updating, the review may be needed. In this study, we compared 2009 year surveying results with past territorial sea baselines results for reviews. As a results, Jeju Island represents a large difference. So, the outputs of territorial sea baselines around Jeju Island should be readjusted. Through this study, the ongoing maintenance of the territorial sea baselines is required. The continuing interest in the maritime boundary, as well as defend in terms of protection for undersea resources are needed.

The countries are trying to expand the sea limit such as the territorial sea, fishing zone or the exclusive economic zone as far as the Law of the Sea permit to do for the benefit of their national interest. Especially, they are eager to claim the base point where it locates far from the coastline even if it is uninhabited island or reef under the sea. The baseline has been claimed to maximize the territorial sea. Another way to expand the sea limit is to lower the vertical datum to change the land limit. China claimed Dongdo which is located about 79 miles far from the coast as the base point. Japan also claimed many uninhabited island or the reef which is located very far from the coast such as Okino Dorishima. As Korea is the party who negotiate the maritime limit with Japan and China, we should be keen and sensitive on the issues claimed by neighboring countries in terms of base point and the baseline. This paper is to review the characteristics of the base points or baselines of neighboring countries and to suggest the views how to maintain and to relocate our base points. As western coast of Korean peninsula is one of the largest tide fluctuation zone in the world, with long tidal record to prove the vertical datum adjustment, Korea can find the way to lower the vertical datum especially in Yellow Sea. So, major and critical tidal station has to be set up along the western coast to verify tide fluctuation record which can be met with international standard.

Territorial sea baseline is a borderline, with the effectuation of the United Nations Convention on the Law of the Sea of 1982, for the related sea zone negotiations with neighboring countries. Its position must be determined to international standard like WGS84 coordinate system. In this study, GPS survey for territorial sea points was performed to determine territorial baseline around five islands in the yellow sea, and the results of them were compared with previous coordinates. Territorial sea point, outermost spot of a nation's realm, tend to be placed in end up low-tide elevations or precipice. Therefore traditional surveying methods are hard to take accurate observations, so that GPS survey is most effective. Through the study, the scientific and reasonable methods for GPS surveying procedure is presented. The results of coordinate comparison show that there are wide difference between the old and new coordinates, and it is necessary for the whole area of islands to calculate displacements by GPS surveying.

Nowadays, the value of the ocean is growing noticeably throughout the world in accordance with the development of the industrial society and increase in the number of the ocean related economic activities. Therefore the pursuit of more waters has led more disputes amongst many maritime powers in the world. In this study, the territorial basepoints are recalculated methods to develop their accuracies to settle a boundary issue among nations.

Intense competition for resources has forced many countries pay attention to their eyes to the ocean. Therefore, the disputes and the conflict over the delimitation of the EEZ and continental shelf will be sharpened. Since 1982 Law of the Sea Convention, Korea has opened the talks with Japan and China to discuss the boundary issues as the adjacent water zone is less than 400 miles between Korea and Japan and Korea and China. This study is to review the important rules and techniques for the delimitation of the maritime boundary which have defined in the Law of the Sea Convention and IHO-51 technical guide and to figure out how to build the maritime delimitation GIS DB to negotiate effectively with the neighboring countries. Definition of the base point and baseline will be the utmost important concept to delimit the ocean boundary. The policy makers and the specialists who prepare for the international negotiation meeting between the countries have to be ready to draw the maritime boundary for our best interest under the Law of the Sea Convention. The negotiation strategies and the principles can be made with the concrete and reliable database relevant to maritime boundary issues. So effective and fast strategic decision for negotiation can only be made based on maritime boundary delimitation GIS DB.
