지적정보는 정보자체가 가지는 높은 보안과 고유의 특성으로 인해 유통 및 활용에 어려움이 있고, 타 기본공간정보와의 융복합을 위한 상호운영성이 미흡한 실정이다. 하지만, 정보의 개방과 통합은 당연한 시대적 흐름으로서 개방과 통합의 범위는 점차 확대되는 추세에 있다. 최근, 정보의 공개 및 유통을 효율적으로 지원하기 위해 공간정보에 대한 인프라 즉, 표준에 대한 논의가 활발히 진행되고 있다. 정보간 융복합과 서비스 측면에서 다양한 분야별로 많은 표준들이 개발, 운영되고 있는데, 특히, 메타데이터 표준이 관심의 대상이 되고 있다. 정보의 유통 및 서비스를 효율적으로 지원하기 위한 메타데이터 표준은 정보에 대한 정확한 설명을 제공하고, 사용자가 정보를 선택하고 활용하는데 도움을 줄 수 있는 부가정보를 제공하는 중요한 역할을 수행한다. 따라서, 본 연구에서는 지적정보가 다양한 분야에서 활용되고 수요가 창출될 수 있도록 한국의 환경에 맞는 지적정보 메타데이터 표준(안)을 설계하고자 한다. 지적정보의 특성을 감안한 메타데이터 표준의 구성을 통해 정보의 유통 및 서비스를 조기에 실현하고, 타 공간정보와의 융복합을 통한 시너지 창출 및 국가 기본공간정보로서의 역할을 충실히 수행할 수 있을 것으로 기대한다.

본 연구에서는 시공간 제약뿐만 아니라, 데이터의 다양성에 따른 제약조건까지도 최소화하여 온라인상에서 지리정보 활용성을 제고하기 위해 기존의 국가지리정보유통망을 지리정보통합포털로 발전시키기 위한 방안을 제시하였다. 이를 위해 미국의 지리정보포털인 GOS(Geospatial One-Stop)를 모델로 하여 우리나라 국가지리정보유통망을 지리정보통합포털로 발전시키기 위한 모델을 수립하였다. 지리정보통합포털 모델은 개방형 분산프로세싱 시스템 구조에 대한 In 국제표준인 RM-ODP를 기반으로 하여 전사적 관점, 정보관점, 전산관점, 공학관점에서 수립하였다. 이를 통해 국가지리정보유통망을 기반으로 각종 지리정보 및 지리정보서비스에 대한 접근성을 제고함으로써 국가차원에서 GIS활용도를 높이는데 기여할 수 있을 것으로 기대된다.

Recently, as the growth of the application of geographical information in various application fields, a geographic information system(GIS) has been building for using them efficiently. GIS has been managing them in use data format individually. To service geographical information based distribution efficiently, there must be a Data Conversion System that can deal with converting of GIS geographical information with incompatible formats. Therefore, in this paper, we design and implement a Spatial Data Translation System with international standard to convert geographic data efficiently.

최근 유비쿼터스를 비롯한 정보기술의 급격한 발전에 따라 GIS를 통하여 누구나 일상 속에서 직접 지리정보를 활용할 수 있게 되면서 공공분야 및 연관 산업분야에 큰 파급효과를 가져오고 있다. 특히, 지리정보의 유통 방식이 기존의 공급자가 제공하는 지리정보에 대해 조회 위주에서 벗어나 현장에서 실시간으로 지리정보를 가공하고 직접 갱신할 수 있는 양방향 서비스로 진화하면서, GIS는 u-City 구현에 필수적인 위치기반 공공서비스 인프라 구현을 통해 민간의 내비게이션, 텔레매틱스 등 관련분야 시장규모가 해마다 급속히 성장하고 있다. 하지만 이러한 상승세에도 불구하고 여전히 기관마다 서로 유사한 서비스를 제공하는 경우가 빈번하고, 민간의 대다수 유관업체들 역시 아직 지속적인 수익모델을 찾지 못해 단말기 제조 등 특정 분야에만 머무르고 있는 실정이다. 따라서 업종특성에 맞는 보다 구체적이고 유망한 신규 사업모델의 개발이 시급하다. 본 연구는 GIS 특성에 근거하여 사업모델 개발에 필요한 성공요인을 도출하고 그 타당성을 분석함으로서, 이를 통해 다양한 성공적인 지리정보 활용 비즈니스 모델의 구현과 평가에 기여하고자 한다.

The rapid development of the information technology has passed over the implementation of the virtual reality. It is realizing information services that are form of the globalization, based on the Internet. In addition, the effort to apply IT to public administration for public services has been made. The remarkable development of computer hardware has overcome the limit of the information distribution and emerged for practical use in various fields such as public institution, underground facilities management, tourism industry development etc. However, the practical use of Virtual Reality with Three-Dimensional GIS on disaster management by Korea National Emergency Management Agency is very much low. Therefore, this studies focus on how to use 3-Dimensional GIS for the purpose of fire disaster prevention. The studies also discussed, through understanding of the limitations of 2-Dimensional GIS, the establishment of basis for fire prevention technology development and its utilization among those ubiquitous city paradigms, which have become so much issues these days.

Enterprises requires the logistics information system to reduce logistics costs and ensure clearness of distribution. However, the system is adopted only by large corporations due to diversity of work and the initial cost for construction. In this study We have attempted to develop an information system capable of efficiently. Controlling and managing logistics by investigating division of duties and existing problem. Using small and medium-sized enterprises engaged in the distribution business as a model. For real-time monitoring of logistics information. We have constructed a system using new technologies such as GPS, mobile and wireless communications and made use of web GIS as infrastructure. Developed by the logistics information systems, We will control overall logistics work and reduce logistics costs and processing time as well.

Last-Mile delivery optimization plays a key role in the urban supply chain operation, which is the most expensive and time-consuming and most complicated part of the whole delivery process. The urban consolidation center (UCC) is regarded as a significant asset for supporting customer demand in the last-mile delivery service. It is the key benefit of UCC to improve the load balance of vehicles and to reduce the total traveling distance by finding the better route with the well-organized multi-leg vehicle journey in the urban area. This paper presents the model using multiple scenario analysis integrated with mathematical optimization techniques using Geographic Information System (GIS). The model aims to find the best solution for the distribution network consisted of DC and UCC, which is applied to the case of Ulaanbaatar Mongolia. The proposed methodology integrates two sub-models, location-allocation model and vehicle routing problem. The multiple scenarios devised by selecting locations of UCC are compared considering the general performance and delivery patterns together. It has been adopted to make better decisions the quantitative metrics such as the economic value of capital cost, operating cost, and balance of using available resources. The result of this research may help the manager or public authorities who should design the distribution network for the last mile delivery service optimization using UCC within the urban area.

Purpose: This study aims to utilize geographic data to analyze how various retail formats of large-scale stores around the traditional market affect the performance of the traditional market in Seoul, Korea. Research design, data, and methodology: The two types of catchment areas were demarcated (circle of 1km radius and Thiessen polygon) for each traditional market, and the large-scale stores located within each catchment area were identified for 153 traditional markets in Seoul, Korea. Additionally, multiple regression analysis was utilized. Results: The results revealed that the influence on the performance of the traditional markets were different depending on the retail format of the large-scale stores. Large discount stores were found to have a negative effect on the sales and the visitors of traditional markets, whereas complex shopping malls and department stores had a positive effect on the traditional markets. Conclusions: As a result of the differences in the retail format such as product categories and leisure functions, the impact of some large-scale stores on the traditional market may have a greater agglomeration effect than the consumer churn effect. Therefore, it is suggested that in the regulation of these large-scale stores, the differences in retail format should be considered for the future.

Purpose: This study aims to not only measure the elderly welfare supply index but investigate spatial patterns and determinants of local elderly welfare services in South Korea. Research design, data, and methodology: The index for local elderly welfare services is measured by employing standardized scores for critical variables related to elderly welfare. The present study utilized the GIS technique and Moran's I index to examine spatial patterns of elderly welfare services. The determinants of local elderly welfare service are analyzed by a series of regression models using R. Results: Spatial imbalance and asymmetric distribution were serious in the supply of elderly welfare service. It was also confirmed that the factors affecting the level of welfare services for the elderly vary depending on the type of service. In particular, the higher the proportion of the elderly population and the social welfare budget, the lower the level of welfare services for the elderly. Conclusions: Given the circumstance of spatial mismatch between supply and demand for elderly welfare services, it is necessary to consider and provide policy tactics about how the economic benefits and welfare budgets generated in the region can contribute to strengthening the welfare service system for the elderly.
