  • Geological map and data are needed for land use planning, resources development, geological hazard prevention, environment protection and education, Since the nationwide geological database in Korea has not been constructed yet, there are many problems in using the geological map and data. There are many problems such a stratigraphy unestablishment, map conservation and edge matching in geological paper map. Therefore it is difficult to construct the geological map database, but the geological map database must be constructed as soon as possible as one of national thematic map. In this study, geological maps of pilot area such as Ansung geological map on a scale of 1:50,000, Busan on a scale of 1:250,000, Namchang on a scale of 1:25,000 and the whole Korean peninsula on a scale of 1:1,000,000 were designed and constructed to database using Geographic Information System(GIS). In addition the geological map management program was developed by GIS program. The digital geological maps were produced using the constructed geological database. The database could be of access through Internet World Wide Web(WWW) environment and be distributed in Compact Disk(CD).

  • Currently, the necessity of inter-system integration and sharing system increases to additionally construct and efficiently utilize the geographical information data in accordance with the increase in demand for geographical information. The provision of the data within the domestic sharing system is led by the tasks within national geographical information distribution network or intra-local governmental combined system. However, any voluntary geographical information sharing cooperation body is increasingly required with the increase in necessity of administrative cooperation among neighboring metropolitan areas, including space planning and development. Accordingly, this study is aimed at looking into the constitutions and roles of cooperation bodies within metropolitan areas by the composition, distribution, update and management of data with special regard to overseas advanced cases whose sharing systems and their effects are highly evaluated, and at presenting any model of the domestic future voluntary sharing cooperation organization within metropolitan area.

  • The watershed information of the Mankyung River and Dongjin River is obtained and analysed using the GIS tool. The informations i.e., digital map, land use, point sources, weather station, water quality measurement station, and pollutants load unit are managed by DB system. The slope, rainfall, and generated pollutants loads of COD, TN and TP which are the input data of the rainfall-runoff-pollutants load model are estimated. From the analysis of the collected and generated data, the almost watershed area is composed of agricultural lands except the upstream regions. The population and industrial area are densely located in Cheonju City and Iksan City, whereas the farming areas are widely distributed.

  • 최근 정보 관련 산업 발달과 더불어 공간 정보의 중요성이 점점 강조되어, 국가 차원의 지리정보체계가 구현되고 있다. 국토지리정보원이 구축하고 있는 수치지도는 DXF로 제작되는데, 이 DXF맵은 GIS분야에서 필요한 속성정보나 위상정보를 갖지 못하여 지리정보 통합에 어려움이 있다. 지리정보의 여러 분야에 걸쳐 효율적인 데이터의 공유가 가능하도록 DXF파일에서 공간 개체를 추출하는 연구는 매우 중요하다. 본 논문에서는 DXF 파일에서 다양한 공간 개체를 추출하는 효율적인 공간 개체 추출기를 제안한다. 공간 개체 추출기는 DXF파일을 구성하는 요소들 중에 POLYLINE, POINT, CIRCLE, TEXT, ARC, LINE의 수치값을 비교하여 그에 해당하는 좌표값을 DAT 파일에 저장한다. 제안된 시스템은 웹상에서도 사용할 수 있다. 사용자는 단순히 웹서버에 DXF 파일을 업로드해서 공간 개체 추출기를 실행하여 결과를 다운로드 받아 활용할 수 있다.

  • Standards are essential to facilitate the efficient use of GIS data. International Standards such as ISO TC211's 19100 series and various technical specifications from OpenGIS Consortium are some of the examples of efforts to maintain the interoperability among GIS applications. This paper aims to provide the effective policy directions that can increase the use of GIS standards by providing the comprehensive list of priorities in developing GIS standards. This paper reviews the current status of the use of GIS standards in the field and analyses the use pattern. Also this paper examines the need for revision of the existing standards and new standardization efforts based on the current status of International Standards. Based on the analysis of the use pattern of the current GIS standard, this paper suggests a policy directions which emphasizes the need for more efforts in standardization of geographic information services standards and more coordination among all standard-related stakeholders in government and industry.

  • Using ArcGIS Model Builder, with emphasis on the importance of ecology and user friendliness, a model for site selecting tool is developed. This tool is developed by establishing standardized method for data selection and analysis with evaluation criteria using GIS. For this task, our first action was to objectively define and establish 18 elements to evaluate the potentiality of the site based on extensive literature reviews. These 18 elements reflect environmental, social/cultural and legal aspects that may influence the decision process to select the desired site. Secondly, using ArcGIS Model Builder, 18 analytical elements were made into thematic mapping which represent systematically organized graphic input to the model with automatic double check system and overlay analysis capability. Thirdly, to validate the effectiveness of the developed model, site location analysis was performed using the actual site, Buk-ku, Pohang.

  • 국가지리 정보체계 (NGiS: National Geographic information Systems) 기본계획 하에서 국가수치기본도가 완성되었음에도 불구하고 교통부문에 GIS의 활용이 미흡하다. 그 이유는 기존 교통관련 S/W가 교통GIS DB를 받아들일 수 없기 때문이다. 이러한 시점에서 본 연구에서는 NGIS에 기초한 교통GIS DB의 이용활성화의 일환으로 교통GIS DB와 기존 교통계획S/W와 상호 Interface할 수 있는 전환 모듈을 개발하였다. 구체적으로는 기존 GIS S/W를 활용하여 교통GIS DB와 기존 교통계획 S/W인 TRANPLAN간의 연계모듈을 개발하였다. 최종적으로는 개발한 연계모듈을 서울시 강남구, 서초구와 경기도 과천시, 용인시에 걸친 일대를 시범지역으로 적용해보았다.

  • The on-going pre-environmental investigation at present is performed by separate numerical analysis of each provision which makes integrated pre-environmental investigation is difficult. The application of numerical data is insufficient, which results to the deterioration of environmental investigation result's objectivity. A lot of time and money is required for the investigation. In this study, the spacial analysis function of GIS was applied on the 8 pre-environmental investigation factors. Pre-environmental investigation GIS DMS(Decision Making System) was constructed to make integrated investigation possible through the use of investigation results for each factor. Through the use of the developed pre-environmental investigation GIS DMS and the pre-constructed GIS data, the objectivity of environmental investigation is sufficient and time and cost are reduced. Therefore, this system can be used for pre-environmental investigation during route selection in the initial stages of road construction. Through the numerical and visual data obtained from the system developed in this paper, it is easier to gain the approval of the public. Furthermore, environmental problems due to road construction can be investigated with less time and money during the initial stages of road construction.
