To manage national territory and cadastral data efficiently, accuracy and cost-efficiency in cadastral boundary surveying is inevitable. The efficient management of cadastral data is a very important element in national land management. Survey techniques are being introduced. Recently, improvements in survey techniques have been made with the development of satellite surveying, Allowing accurate and fast surveys. If we can calculate the output accurately in real-time in survey fields, it will open a new method in cadastral detail surveying. According to the classification on Law of cadastral surveying, Cadastral surveying can be divided into cadastral control point surveying and cadastral detail surveying. The control point survey can be divided into cadastral triangulation surveying and cadastral traverse surveying. The detailed survey is usually perform by plane surveying. Among these, cadastral detail surveying will be reviewed in this study. In this study, the combination of the satellites, such as US managed GPS and Russian managed GLONASS was used. In the satellite survey in downtown, data interruption symptoms arose(according to the mask angle of the satellite). Therefore; we combined the satellites to get date more accurately. A block of Haewoondae New City in Busan, Korea, which has Numerical Cadastral Law was selected as the sample area for this study. Block II and III are surrounded by high rise apartments. One side of Block I and IV is level ground and the other side is full of high rise apartments. Especially, Block II is surrounded by high rise apartment houses with 20 meters width. In the results of the study Block II did not satisfy the allowable precision, while Block I, II and IV satisfied the allowable precision of the enforcement regulations of Cadastral Law. Therefore, it is judged that the traditionally used Total Station method should be used for supplementary survey on Block II, in stead.

본 연구의 목적은 전자지도 시장의 질서를 바로 잡고 시장을 활성화시켜 일반국민들에게 보다 나은 지도서비스가 이루어지도록 하기 위해 다양한 지도가격정책 중 저작권적용을 중심으로 한 구체적인 접근방법을 제시하는데 있다. 이를 위해 먼저 현행 우리나라의 저작권법과 외국의 수치지도 저작권 보호 실태를 분석하고, 저작권방식의 적용가능성을 조사하고, 우리나라 지도시장에 미칠 영향을 분석하였으며, 그 최종 방안으로 측량법과 국가지리정보체계의 구축 및 활용에 관한 법률(NGIS법)에 적용하기 위한 개정방향을 제시하였다. 본 연구에서는 우리나라의 수치지도를 저작권법으로 보호하기 위해서는 데이터베이스 제작자의 권리로 보호하는 것이 합당하며, 저작권의 개념을 측량관련법령에 적극 도입하고, 지도품질 개선 및 제반관리를 위해 신탁기구설치의 고려가 필요하다고 판단되었다.

Recently, the old surveying method for acquiring surveying-geo information results had a low economic efficiency and a low dependence of precision because it took much times and high costs. So, we acquired law data by execution of control surveying through Static positioning of DGPS(Ashtech). It is computed plainmetric(X, Y) positioning through postprocessing by Prism S/W. And we computed height(Z) through control surveying by ring-closed leveling surveying. After control surveying execution, we built DEM(Digital Elevation Model) using LDT S/W and accuracy 3D detail surveying by EDM(Electronic Distance Measurement) surveying. The purpose of this study was to yield automated digital mapping and the automated amount of materials using ahead data. The conclusions were as follows; First, we built the automated amount of materials system and got high efficiency about personnel, times and precision. Second, when, people precisely positioned on railroads of a high-speed railroad and used GPS surveying, the result was permitted. Finally, it was possible to draw automated profile and cross-section using the 3D terrain model build with the DEM technique.

한국의 지적측량 성과검사는 지적법에 근거를 두고 시행되며 토지소유자나 국가의 신청에 의해 토지 이동 정리를 소관청이 최종 지적측량검사를 실시하여 지적공부에 등록하도록 되어 있다. 따라서 지적공부 정리전 소관청은 측량성과를 검측해서 측량오차가 허용오차내에 있는가를 확인하여 그 범위내에 있을 때 그 결과치에 준해 지적공부를 정리할 의무를 갖는다. 본 연구는 성남시 3개구를 연구대상지로 선정해 연도별 토지이동상황을 조사 분석하고 소관청의 지적측랑 성과검사 현황과 지적측량 관련 인원 및 장비 현황을 분석해서 그 문제점을 도출하여 향후지적측량 검사시 효율적인 기초자료를 제공하여 국가행정의 능률을 높이고자 한다.

서로 인접하는 토지소유자간에 경계분쟁이 발생한 경우 원칙적으로 지적도를 기준으로 그 침범여부를 가려야 하는데 이 때 지적공부상의 경계를 실지에 복원하기 위하여 행하는 측량이 바로 경계복원측량이다. 토지반환, 건물철거 등의 민사사건에서 실무상 접하는 거의 모든 측량이 여기에 해당하며 그 측량성과는 판결의 결과에 결정적인 영향을 미친다. 그러나 경계복원측량은 측량을 수행하는 측량기술자 개인의 지식과 경험에 의존함으로써 상이한 측량성과를 가져오는 경우가 많다. 이 글은 인접하는 토지소유자간의 경계분쟁이 있는 경우에 이를 해결하기 위한 수단으로 행해지는 경계복원측량이 소송실무에서 어떻게 작용하는가. 특히 경계복원측량에 관한 법 규정과 대법원판례를 검토함으로써 경계복원측량의 법리가 무엇인지를 파악하고자 하였다. 이를 통해 측량기술자가 경계복원측량을 실시하는 경우에 이러한 판례 법리에 입각하여 측량하도록 함으로써 일관되고 신뢰성 있는 측량성과를 달성하는데 기여하고자 한다.

On 15 December 2015, China seized an underwater drone belonging to the U.S. in the South China Sea. The underwater drone was then about to be retrieved by the Bowditch, a U.S. naval ship.Although China returned the underwater drone to the U.S. on 20 December 2016, the incident resulted in the considerable controversy involving the use of underwater drones. The reason for this is that the seizure of the underwater drone happened in the exclusive economic zone (hereafter referred to as "EEZ") of the Philippines. Part XIII of the United Nations Convention on the Law of the Sea (hereafter referred to as "UNCLOS") governs the matters of marine scientific research (hereafter referred to as "MSR"). If a State intends to use an underwater drone in the EEZ of another coastal State for the purpose of MSR, the former has to obtain the consent of the latter in accordance with relevant provisions included in Part XIII of the UNCLOS. However, it is not obvious whether the consent of a coastal State should be required to launch an underwater drone in the EEZ of the State for the purpose of hydrographic surveying or military surveying. Maritime powers such as the U.S. regard hydrographic surveying or military surveying as part of "other internationally lawful uses of the sea related to these freedoms, such as those associated with the operation of ships, aircraft and submarine cables and pipelines" found in Article 58(1) of the UNCLOS, or part of the freedom of the high seas. This interpretation is not incompatible with the implications that the UNCLOS has. Nevertheless, Korea cannot accept this kind of interpretation that is supported by maritime powers. The freedom of hydrographic surveying or military surveying could imply that the EEZ of Korea would be full of underwater drones launched by China, Japan or even Russia. Hence, Korea should claim that the data collected for the purpose of MSR cannot be distinguished from that collected for the purpose of hydrographic surveying or military surveying. This means that hydrographic surveying or military surveying without the consent of a coastal State in the EEZ of the State should not be permitted.

In automatic map generalization, the formalization of cartographic principles is important. This study proposes and evaluates the selection method for road network generalization that analyzes existing maps using reverse engineering and formalizes the selection rules for the road network. Existing maps with a 1:5,000 scale and a 1:25,000 scale are compared, and the criteria for selection of the road network data and the relative importance of each network object are determined and analyzed using $T{\ddot{o}}pfer^{\prime}s$ Radical Law as well as the logistic regression model. The selection model derived from the analysis result is applied to the test data, and road network data for the 1:25,000 scale map are generated from the digital topographic map on a 1:5,000 scale. The selected road network is compared with the existing road network data on the 1:25,000 scale for a qualitative and quantitative evaluation. The result indicates that more than 80% of road objects are matched to existing data.

Many countries have changed her geodetic reference system from local system to global system because of the global network's necessity And, also Korean geodetic reference system changed from Tokyo datum to Global geodetic reference system since 2003 as the revision of Survey Law and Korean reference ellipsoid changed from Bessel 1841 ellipsoid to GRS80. Astronomic surveying has been regarded as an important method for absolute positioning of geodetic datum in each countries under the local geodetic reference system. This paper aims to analyses distribution of geoidal heights and ellipsoidal agreement between Bessel 1841 and GRS80 ellipsoid in Korea through comparing both astrogeotic geoidal heights referred to GRS80 and Bessel 1841 ellipsoid by astronomic surveying data which have been surveyed after 1970 in Korea.

Since public awareness on the importance of sea is increasing, a number of states have ratified the United Nations Convention on the Law of the Sea. However several problems on marine boundary making are raising due to the ambiguity of law and importance of sea area. The purpose of this study is to find a logical principal through overall consideration on decision of baseline points which is a criteria of maritime boundary delimitation. Accordingly, this paper considers the current status, problems and measures for marine boundary making and then presents an alternative on it.
