  • GIS 기술은 하루가 다르게 발전하고 있는데 비해서 GIS 기술과 활용방법을 배울 수 있는 교육환경은 매우 열악하다. 이에 따라 공공부문에서는 GIS 응용시스템의 경제적 이용가치가 낮고 산업체에서는 GIS 전문인력을 구하는데 애를 먹고 있는 실정이다. 또한 GIS 분석기술이 다양한 분야로 보편화되면서 GIS에 대한 개념과 기술을 배우려는 교육수요가 급격하게 늘어나고 있다. 이러한 배경 하에서 본 연구는 우리나라 공공과 민간 그리고 대학에서 실시되고 있는 GIS 교육의 실태를 설문조사를 통하여 분석하였다. 그리고 조사결과를 바탕으로 GIS 전문인력 양성을 위한 교육환경 개선방안을 모색하였다. 공공과 민간 대학의 열악한 교육환경을 개선하기 위해서는 무엇보다는 국가차원의 계획적 투자가 필요한 시점이다.

  • In spatial information processing, particularly in non-renewable resource exploration, the spatial data sets, including remote sensing, geophysical and geochemical data, have to be geocoded onto a reference map and integrated for the final analysis and interpretation. Application of a computer based GIS(Geographical Information System of Geological Information System) at some point of the spatial data integration/fusion processing is now a logical and essential step. It should, however, be pointed out that the basic concepts of the GIS based spatial data fusion were developed with insufficient mathematical understanding of spatial characteristics or quantitative modeling framwork of the data. Furthermore many remote sensing and geological data sets, available for many exploration projects, are spatially incomplete in coverage and interduce spatially uneven information distribution. In addition, spectral information of many spatial data sets is often imprecise due to digital rescaling. Direct applications of GIS systems to spatial data fusion can therefore result in seriously erroneous final results. To resolve this problem, some of the important mathematical information representation techniques are briefly reviewed and discussed in this paper with condideration of spatial and spectral characteristics of the common remote sensing and exploration data. They include the basic probabilistic approach, the evidential belief function approach (Dempster-Shafer method) and the fuzzy logic approach. Even though the basic concepts of these three approaches are different, proper application of the techniques and careful interpretation of the final results are expected to yield acceptable conclusions in cach case. Actual tests with real data (Moon, 1990a; An etal., 1991, 1992, 1993) have shown that implementation and application of the methods discussed in this paper consistently provide more accurate final results than most direct applications of GIS techniques.

  • The types of service using location Information are being various and extending it's domain as wireless internet technology is developing and it's application part is widespread, so it is prospected that LBS (Location-Based Services) will be killer application in wireless internet services. This location information is basic and high value-added information, and this information services make prior GIS (Geography Information System) to be useful to anybody. The acquisition of this location information from moving object is very important part for these LBS. After this, when LBS is familiar to everybody, we can predict that LBS system load is so heavy for the acquisition of so many subscribers and vehicles. Moving object database (MODB) system manages objects like subscribes and vehicles that are moving and have telecommunication terminal checked one's location. MODB is consists of 4 part, moving object location acquisition part, moving object location storage part, moving object query processing part, and moving object application p art. In this MODB system, acquisition of moving object location part must provide guarantee location information as well as reduce telecommunication overhead. In this paper, we study of problems in acquisition a huge number o f moving objects location and design some acquisition strategies to reduce telecommunication overhead. And after implementation these strategies, we estimate performance of this system and quality of information.

  • The purpose of this study is to estimate the soil loss amount with Geographic Information System according to the land use change of Buju mountain area in Mokpo city. To estimate the soil loss, Universal Soil Loss Equation which is the most proper technique to predict soil loss in this site condition is adopted and IDRISI, a raster GIS software, is used. GIS application with USLE is very efficient to estimate soil loss accurately and fastly. In order to decide value and to find application method of USLE factors, we used existing rainfall erosion index, soil erodibility analysis, slope length, slope steepness, vegetation management and practices, which are rated by GIS through the analysis of various studies related USLE. The result of this study was compared with the previous other researches to verify our method of constructing numerical data of USLE's factors. The result of verification of our way showed significance for the soil loss in forest area. But the result of verification for the soil loss in forest area. But the result of verification for the soil loss of cultivated area showed some errors. It seems that this result was due to local variation of topographical map.

  • A GIS-based tunnelling risk management system (GIS-TURIMS) has been developed in this study The developed system uses ArcView 8.2 as a basic platform and the built-in interface(VBA) has been used to perform first-order simplified analyses for prediction of tunnelling-induced ground movements and building damage assessment. The main emphasis in this study was to develop a working framework that can be used in the perspective of tunnelling risk management. The developed system is capable of carrying out computationally intensive first-order analyses for ground movement prediction as well as building/utilities damage assessment with fully taking advantage of the GIS technologies. This paper describes the concept and details of the GIS-TURIMS development and implementation.

  • 1995년부터 시작된 국가GIS 구축사업은 초기에는 공간정보기반을 확충하기 위하여 주로 중앙부처와 공공기관을 중심으로 추진되어 왔으나, 앞으로는 행정업무와 대민서비스를 수행하는 기초자치단체를 중심으로 추진될 것으로 전망된다. 그 이유는 지자체의 행정 업무시스템을 통해서 생산 관리 갱신된 지리정보 데이터가 중앙부처로 연계되어 활용될 것이기 때문이다. 이 연구에서는 향후 중요도가 높아질 것으로 예상되는 지자체 GIS정책 수립을 위해 지자체의 GIS 활용 및 운용실태를 조사하였다. 그 결과 지자체별로 GIS활용의 정도와 수준 차이가 매우 크게 나타났으며, 환경도 아직은 열악한 것으로 분석되었다. 특히 재정자립도가 낮은 지자체의 GIS구축 및 활용수준을 높일 수 있는 대책과 함께 지자체간 정보격차를 줄여갈 방안이 시급한 실정이다.

  • This paper described some applications using Open GIS Component that was called MapBase. There were 4 applications : KSDI(Korea Spatial Data Infrastructure) funded by MOIC(Ministry of Information and Communication), National Plants Resource Management System supported by Korea Forest Service, 7-Underground Facilities Management System of Cheongju funded by MOCT(Ministry of Construction and Transportation), and National Disaster Management System supported by MOGAHA(Ministry of Government Administration and Home Affairs. Because they wanted to access heterogeneous spatial database, it was necessary to select MapBase as their base methodology. The main feature of MapBase was component S/W which provided the interoperability and reusability among GIS applications as well as non-GIS information system through common specification. In this paper, we showed some applications' architectures and functions to increase understanding MapBase. That would help you to make application using MapBase.

  • To improve the reusability and interoperability of GIS components, we propose the registration/retrieval agents, which can search the locating of users' frequently used components in not only the GIS domain but also other spatial information technologies such as GPS, ITS, RS and FM. The registration/retrieval agents increase the reusability through the GIS component based development under distributed GIS components environment and enables the rapid setting of application on the web. Moreover, users can understand easily the information of GIS component and have the effective investment, timeliness and reliability while they have less maintenance effort by agent. In order to design and implement this system on web, HTML and ASP (Active Serve Page), and JAVA were used. In addition, the performance of this system was verified through comparing others, which are similar to.

  • 만약에 사회과학분야 연구자들이 GIS를 활용하고 만족하는 이유를 안다면, 이를 통해 GIS 활용을 확산시킬 수 있는 전략을 마련할 수 있을 것이다. 본 연구는 사회과학분야 연구자들이 GIS를 활용하는 동기요인은 무엇이고, GIS를 활용해 만족을 느끼는 요인은 무엇인지를 분석한다. 이를 위하여 GIS의 강점과 활용요인 및 만족도를 사회과학분야 국책연구원과 지방연구원의 연구자들을 대상으로 조사하여 분석한다. 연구결과에 따르면 사회과학분야 연구자들이 GIS를 활용하는 동기요인은 효율성이며, 활용결과에 대한 만족요인은 사용성이라는 것이 밝혀졌다. 또한 GIS 활용의 동기요인과 만족요인은 전혀 상관관계가 없다는 것도 밝혀졌다. 이와 같은 현상은 사회과학분야 연구에서 GIS 활용 확산을 저해할 수 있다. GIS의 활용도를 증대시키기 위해서 GIS 활용과 만족요인을 연계시킬 수 있는 방안이 필요하다.
