In the fixing of positions on the ground, the fixed position is determined by triangulation, traverse surveying and astronomy surveying. However, when the positional target is moving, it has been impossible to determine the location of position. Satellite position fixing system can be used anywhere on earth arranged in 20,000km high with 24 satellites. The location of car has been determined by the distance from starting point. The theoretical method of the fixing carposition is using satellite position fixing system. This study is the part of the experiment which is done for the development of the system used in Car-position fixing system. In this study, the comparison of one point positioning and relative positioning has been made.

Geo-Spatial information system(GSIS) processes the information to control geographic and attribute information, totally and systemetically. Authors built up the database of the landuse by cadastral law. Database of the landuse classified by ARC/INFO GSIS software used in Onchun stream, KumjungKu. Aerial photo of Pusan interpret every 10 years. Because the area which is higher than the ground height 100m is the green belt, study area is lower than the ground height 100m which can be developed. It is possible to find the river status of the model area on the aerial photo of 130 scenes in 1973, 1983 and 1993 In this study, authors knew analysis of landscape with interpretation of the aerial photos.
교통사고 정보분석시스템 구축을 위한 기초적 연구 : 부산시 금정구를 중심으로 Pusan

부산시 금정구 지역의 교통사고 잦은 곳을 선정, 운전자측의 원인을 명확히 함과 동시에, 도로구조 등의 발생지점 정보, 기상기후 등의 발생시점 정보 등을 상세히 기록하여, 교통사고 원인에 근간을 둔 교통사고 정보분석 시스템을 개발하고, 교통사고발생요인을 수량화 Ⅰ류로 통계 분석함으로써 금정구지역의 교통사고발생요인으로 좌회전유형, 주행속도, 주차유무, 현시수 등 4가지를 추출하여 교통사고를 미연에 방지하기 위한 의사결정을 지원할 수 있도록 하였다. The purpose of this study is to establish a Traffic Accident Information Analysis System with the human, spot and time elements in Gumjung-Gu that be based on cause of traffic accident. Accordingly, this system is to help out decision making for the countermeasures of traffic accident in black spots using Quantification I method to draw out 4 factors (left turn, average speed, parking, phasing).

Global positioning system and its vectors are referenced in the WGS 84 datum. Because Tokyo datum is used in Korea, usually geodetic coordinate system transformation is need to use GPS data directly. Basically GPS surveying results are length and direction of base line. Authors could use the relational distance and direction within two stations, directly, in practical coordinates system without the transformation of coordinates in GPS data. The triple differenced carrier phase obserbables yields the relative positioning between the co-observing receivers, usually referred to as the 3-dimensional vector between the stations. In this study, we could obtained the practical position data without coordinate transformation, with known geodetic results of Korea and GPS triple differenced carrier phase observables.

In Pusan city, more and more efficient car management is needed for insufficience of accomdating road abilitys. GPS being a global navigation and positioning system works under any kind of weather and no visibility requirement in addition to highly accurate three dimensional positioning information, so tremendous impact from GPS has occureed. Using the position and time data of GPS, we can analyze the velocity of car and utilize GPS data for monitoring statistics and traffic capability of the road. Because of storing capacity the position of car GPS data, we can analyze the navigation path of car. Therefore we will effectively use road resource by GPS data. In this study, we developed programs that could monitor the map of car-navigation, analyze distribution of velocity and traffic management by GPS.

JAVA is interactive, platform idependent and object-oriented language and meets all needs on Internet GIS. This paper introduce JAVA based GIS program to manipulates various geographic data on internet, communicating interactively and transfer real-time data between server and client. This program analysis roof detector data in all part of pusan area and indicates the traffic states, the road surface conditions, weather information, the shortest cut, and road names in JAVA client windows. Also this study shows various techniques of real time traffic informations.
라플라시안 경계강조에 의한 MRI 영상의 3차원 입체모델의 구현
배상진,최철웅,강인준 釜山大學校生産技術硏究所 1996 生産技術硏究所論文集 Vol.50 No.-
초음파, 단층촬영(CT:Computed Tomography), 그리고 자기공명영상(MRI:Magnetic Resonance Imaging)등이 3차원 입체모텔을 정확하게 표시하기 위하여 실제 환자들의 해부를 통하여 개발되어져왔다. 3차원 입체모델은 대상물의 체적, 위치, 형태등 중요한 정성적, 정량적 정보를 제공할 수 있다. 그러나 자기공명영상은 2차원 다층구조와 복합구조로 구성되어 있어 실제적인 3차원 모습을 알기 어렵다. 본 논문에서는 자기공명영상을 수치데이타화하여 영상처리기법으로 경계선을 추출하고 사진측량기법의 좌표변환으로 동일좌표화 하였으며, Ray Tracing기법에 의하여 3차원 입체모델을 구현하였다. A Method has been developed which allows accurate modeling of 3-Dimension image data such as CT or MRI, with the anatomy of the actual patient. 3-D modelling give some important qualitative and quantitative information about object volume, location and type etc. But the MRI images have 2-D multi-layer and complex constructure, so it is difficult to know real 3D shape. In this paper, MRI images are enhanced of edge by image processing and digitized to digital data. The coordinate of object is transformed to same coordinate system by photogrametry technique and 3-D modelling is made to 3D model by ray tracing technique.
