  • 본 연구에서는 인천 지역의 범죄의 특성 지역을 분석하기 위하여 기존의 이론적인 논의에 기초하며 AHP와 GIS와 연계를 통해 분석하고자 하였다. 이를 위해 인천의 범죄 우발지역을 볼 수 있는 공간적 패턴과 경찰서 내지 파출소의 적지를 선정하고 자료 분석 및 데이터 수집과 통틀어 공간 분석을 수행하며 이러한 분석을 통해 얻어진 여러 가지 요인들과 범죄 율을 나타내어 최종 자료를 구현하기 위한 연구를 한다. 범죄 율의 공간적 표현을 위해서 수식을 이용하여 범죄 율을 구했으며 인구 및 정확한 데이터들을 수집하여 분석하고 그대로 반영한다. AHP를 이용하여 설문조사 및 객관적인 판단과 가중치를 판단할 수 있는 중요한 척도가 되었으며, 이것들을 반영하여 최종 결과물에 현실성을 더하여, 실제로 예방조치를 취할 수 있도록 할 수 있을 것이다. 또한 GIS 소프트웨어에서 제공되는 좌표체계와 데이터베이스 및 SQL 등을 이용하여 현실성과 정밀성을 더하여 활용될 수 있음을 확인하였다.

  • 우리나라 연안해역에 급증하는 해상풍력단지 등 대규모 해양개발 행위로 인해 무분별한 해역을 점용하게 됨에 따라, 과거 관습적으로 이용해오는 해상교통로와 상충되어 발생하는 사회적 충돌이 문제가 되고 있다. 특히, 선박 대형화 및 자동화, 자율운항선박 등장 등 해상교통환경 변화에 따라 안전한 연안 해상교통환경 조성이 시급한 상황이다. 모든 연안해역의 해상교통 흐름 및 교통밀집도 분석에 따른 관습적 해상교통망을 식별하고, 이를 지정·구축하고자, 빅데이터 및 지리정보시스템(GIS) 기반 해양공간분석기법을 활용하여 검토 및 분석하였다. 이렇게 분석 및 식별된 결과는 DB화하여 디지털 GIS 관리시스템과 연계하도록 추진중이다.

  • This study proposes a method to measure the positional accuracy of the implemented GIS polygon data. Also, it aims to present a possibility to analyze the occurrence types of positional errors by improving the measuring methods of positional accuracy based on the existing individual methods and by linking individual methods. As a result of the actual application of the methodology to the test area, it was possible to measure the positional accuracy in target test areas and to analyze the occurrence causes (types) of positional errors through each index linking (linking methodologies). Also, research results allowed confirming the applicability of the methodology. However, complementary research for each standard numerical value is recommended in order to ensure the validity of methodology.

  • Most of the evaluations of environmental effect of construction of road do not run parallel with the evaluation of the propriety of the business, but it just reviews how to reduce contamination before the beginning of the construction work. This reveals the limitation of the induction of environment friendly development from the fundamental. In this study, a function of GIS spatial analysis for 9 elements of pre-evaluation of environmental effect has been introduced, and a GIS decision making system for environmental effect of a road has been established for an integrated evaluation by using individual evaluation result. By using GIS decision making system for pre-evaluation of environmental effect that has been developed in this study and the GIS data that has been collected, it would be possible to decrease time and money for evaluation as well as fulfill the requirement of objectivity. Therefore, it would be possible to apply for pre-evaluation of environmental effect when deciding on the route of the road at the beginning stage of the construction work. Also, through the system developed in this study, the construction body could easily induce a mutual agreement with the residents by the visual evaluation material, which might result in an evaluation of environmental effect while decreasing time and money at the beginning stage of the construction.

  • The purpose of this study is to develop rail rockfall and landslide information system to manage spatial database using GIS. For this, a spatial database containing information such as railroad, map, topographic analysis, meteorological data, and rockfall has been constructed for 2.5 km or 5 km buffer zone from the Kyungchun, Youngdong, Jungang, Taebak and Jungsun Rairoad where risk of landslide occurrence potential is high. For management of the spatial database, railroad rockfall and landslide information system has been developed. The information system consists of view, table, chart, layout and project environment. The functions provided in the system are data conversion, editing, labeling, zoom in and out, map making, graphic editing, text DB management, charting, on-line help as well as input, retrieve and output of spatial database. The system was developed using ArcView script language Avenue, and consisted of pull-down menus and icons for easy use. The spatial database and the information system can be used to rockfall and landslide management and analysis near the railroad as basic data and tool.

  • 기존의 건설지원시스템은 주로 문자정보를 대상으로 구축되어 지형이나 공간정보와 같은 실세계에 대한 정보를 제공하는데 취약점이 있으나, GIS(Geographic Information System)는 이러한 문제에 대해 공간정보의 제공뿐만 아니라 설계지원시스템과 연계하여 효율적이고 체계적인 정보의 분석 및 지원 기능을 제공해 줄 수 있을 것으로 기대된다. 이에 더하여 다양한 네트워크의 구축 및 이를 통한 정보서비스의 발전은 GIS의 제공방식과 내용을 변모시키고 있으며 네트워크 상에서 즉각적으로 사용자에게 다양하고 동적인 GIS 솔루션을 제공할 수 있는 Web GIS의 활용이 확산되고 있다. 본 연구에서는 건설진행상황을 즉각적으로 확인하고 실시간으로 업무보고 및 업무지시를 수행함으로써 원격공정관리를 가능하게 하고, 나아가 단지 문서적인 업무보고에만 의존하여 보고자의 의도에 따라 수동적으로 의사결정을 내리던 관행에서 벗어나 Web GIS에 기반한 건설공사 정보관리시스템을 개발함으로써 건설공사 현황을 직관적으로 판단하고 의사결정을 내릴 수 있는 시스템을 구축하였다.

  • The purpose of this study is to develop a series of trend analysis models for industrial water consumption and to propose a blueprint for the integration of the developed models with GIS. For the consumption data acquisition, a real-time sensing technique was adopted. Data were transformed from the field equipments to the management server in every 5 minutes. The data acquired were substituted to a polynomial formula selected. As a result, a series of models were developed for the consumption of each day. A series of validation processes were applied to the developed models and the models were finalized. Then the finalized models were transformed to the average models representing a day's average consumption or an average daily consumption of each month. Demand pattern analyses were fulfilled through the visualization of the finally derived models. It has founded out that the demand patterns show great consistency and, therefore, it is concluded that high probability of demand forecasting for a day or for a season is available. Also proposed is the integration with GIS as an IT tool by which the developed forecasting models are utilized.

  • Space Syntax methodology can be quantitatively calculated spatial cognitive analysis by number of turns_ In the existing GIS-based spatial information service provide 'physical distance' due to the shortest distance as a priority. but pedestrians tends to choose the path with concerned a lot of emphasis of safety, more vitality way from the crime at night, traffic accidents, and comfort on a road. Human's 'psychological distance' may reflect the spatial information services and provided path should be. In this study, using GIS Road Data implements the axial map with idea of the linear simplification principles. Traditional axial map of the Space Syntax get the assumption from the actual traffic values by comparing the results of correlation relationship. Through these methods, the actual relationship between traffic and test values have the correlation value($R^2$= 0.5387) 50% level and was able to get the results.

  • It is difficult for existing construction support system to provide real-world information such as geographical and spatial data, geographic information system is expected to be able to supply efficiently analyzing and supporting function as well as actual data by connecting construction support system. Furthermore, the providing method and content of GIS are varied by building various network and information service, and use of web GIS which can offer diverse and dynamic solution on network is spreaded. In this study, information management system for construction works(CIMSGIS : Construction Information Management System on Web GIS) based on web GIS is developed, which can confirm instantly state of advance and manage construction progress by real-time reporting and instruction. Also CIMSGIS can support decision making on intuitive understanding and manifold operation reporting.
