We changed goo-spatial data of road and urban planning among urban basic facilities to numbers, keyed attribute information in the database and applied to specific area. So, this study shows following results; 1. Finding a new way to contain the information of GSIS as a database properly to the current high industrial & informative society and numbering the base map which needs the most time and endeavor make it possible to integrate and manage map information with various forms and to propose the exact data in a minute. 2. People can synthetically plan as they use the integrates geospatial database of road and urban planning which is kept by every other departments. 3. It can help urban planning to develop operating system which can do edition, revision, management of urban facilities of the basis of map information database.

현재 우리나라에서는 국가 기본도를 비롯하여 여러 축척의 수치지도가 제작되어있다. 그러나 현재의 수치지도는 항공사진측량 또는 위성영상을 이용하여 신규제작이나 수정․갱신이 이루어지고 있지만, 산업의 발달과 국가경제 성장으로 인하여 수시로 변화하는 지형․지물에 대한 즉각적인 수정이나 갱신을 실시하기에는 많은 어려움이 있다. 따라서 본 연구에서는3차원 레이저스캐닝(3D Laser Scanning)을 국부지역에 적용하여 실제 지형과 같은 3차원 공간좌표로 취득하여 수치지도 수정갱신에 요구하는 측위 정확도 제시와 실험에 적용하여 사용자 편의를 제공하고자 한다. Nowadays, various digital maps on a reduced scale were drawn in Korea including the topographic series of a nation. Though these digital maps are drawn and revised by using aerial photogrammetry or satellite image, there are some problems that it is fficultto revise or renew the topography and natural feature immediately which changes frequently. As the countermeasuresof these problems we use 3D Laser Scanning accumbency method, which provides user with convenience andaccumbency accuracy which is required to revise and renew digital maps.

고해상도의 디지털 카메라는 근거리 수치사진측량에서 널리 유용하게 사용되고 있으며 점차 활용도가 증가하고 있다. 또한 사진측량 장비의 급속한 발전으로 정밀도가 많이 향상되었고 컴퓨터를 이용한 지형공간정보체계기술의 발달로 더욱 정밀한 3차원 지형의 재현과 면적 및 토공량 산정이 가능하게 되었다. 본 연구에서는 휴대가 간편하고 수치영상의 자체저장능력을 지닌 디지털 카메라를 이용하여 촬영조건의 다양한 변화에 따른 위치오차를 분석하였으며 광속조정을 통하여 높은 정확도의 화소 좌표를 획득하여 3차원 지형의 모니터링을 위한 기초 자료로 사용할 수 있도록 하였다. 또한 근거리수치사진측량기법의 국부지역모형생성과 문화재의 보존과 복원을 보다 효율적으로 하기 위해 수치정보 분석에 관한 연구를 수행하여 봉분의 3차원 구현에 대한 활용방안을 모색하였다. Digital high resolution cameras are widely available, and are increasingly use in digital close-range photogrammetry. And photogrammetry instruments are developing rapidly and the precision is improving continuously. The building of 3D terrains of high precision are possible and the calculation of the areas or the earthwork volumes have high precision due to the development of the technique of the spatial information system using computer. Using the digital camera which has capacity of keeping numerical value by itself and easy carrying, we analyze the positioning error according to various change of photographing condition. Also we try to find a effective method of acquiring basis data for 3D monitoring of high-accuracy in pixel degree through digital close-range photogrammetry with bundle adjustment for local terrain model generation and 3D embodiment of tumulus. In the study is about to efficient analysis of digital information data for conservation of cultural properties.

포장유지관리스시템은 노면의 상태를 정밀히 조사․분석하고 유지보수에 대한 계획을 수립할 수 있는 시스템으로 구성하여야 한다. 현재 구축되어 있는 대부분의 포장유지관리시스템은 전문가가 현장에서 노면의 상태를 조사한 후 그 결과를 입력하도록 되어있다. 현재의 실정과 향후의 포장도로의 증가를 고려할 때 포장도로 전체를 전문가가 직접 조사하는 것은 비효율적일 뿐만 아니라 지속적인 포장유지관리시스템의 유지가 어려운 실정이다. 따라서 본 연구에서는 비디오카메라를 이용하여 도로를 대상으로 차량에 디지털 비디오카메라를 설치하여 도로에서 일정하게 차량속도를 유지하면서 촬영된 디지털 영상정보로 객체 지향적인 언어인 Delphi를 이용하여 도로노면정보(균열, 소성변형, 종평탄성)를 획득할 수 있는 도로노면관리정보추출을 하고, 개발된 시스템은 동영상 및 그래프를 이용하여 시각화 효과를 증진시킬 수 있도록 하였다. Since there has been a sharp upward trend in road maintenance cost as the expansion of road networks increases, running a pavement management system(PMS) is indispensable for efficient and scientific maintenance of the whole road networks with limited maintenance budgets. Therefore, in the study video Camara was used to examine road surface pavements. With digitally mastered-image information that was filmed with a digital video camera fixed on a car travelling on road at a consistent speed, a road surface management system that can gain road surface information(Crack, Rutting, IRI).

Roads have been regarded as a means to accomplish well-balanced land development as well as vital social infrastructure, as a dramatic increase in the number of vehicles and the volume of traffic since the country headed toward the automobile era reflects the growth of Korean economy. Road maintenance along with road construction, therefore, has been considered as essential tasks that must be involved without exception. This means that road maintenance is not an incidental process in road construction, but is equally significant to construction or is an important field that should be treated more seriously. In a consequence, it was found that if databases are implemented in the future with quality digital image information accumulated from studies on roads, they will not only lead to cost reduction in the field of pavement management system and enhance the efficiency of systems, but will be able to provide the field of pavement management system with a large amount of information and data.

In this paper, interpolation for calculation excavation volume of irregular boundary region is applied. Excavation volume of irregular boundary region is based on an extension of Newton-Cotes formulas. As a result, spot levels method by nonlinear formulas provied a better accuracy than the linear formulars to excavation volume. And application of the folmulas is compared with a model test.

To achieve an object of study of korea cadastral systems I got results as follows, First, Because the Cadastral Law whose the cadastral systems of korea known to the public with reference to a parcel contained the physical content is made known to the public with the ownership and the rest rights of land, two laws have kept the duality as Japanese remnants sin 1910's. But in the early days Japan had dualized to keep the cadastral systems and the real property registration systems, in the present two systems is unified with the Real Property Registration Act. In the early days the land Registration systems of Taiwan as the land Registration of Korea as have the dualized form but unified the Land Law present. Second, as the land notification systems did not unified one system, its system resulted in an efficient administration in korea. Third, Cadastral survey have been under taking korea Cadastral survey cooperation and real property registration have been executing in the law agent association in korea. In Japan Cadastral survey under takes surveyors and in Taiwan Cadastral survey Controls government directly. Forth, as to the land notification systems peoples perceived that it is irrational, illegal, monopolistic the mentioned.
