The proposed offshore wind farm projects, i.e., Mooudo offshore, Yeonggwang-Gochang offshore, Saemangeum offshore, Imjado offshore and Gadeokdo-Dadeapo offshore, were compared and analyzed using the Korea National Wind Mapand Wind Farm Suitability Assessment System developed by the Korea Institute of Energy Research. The suitability of the proposed areas was comprehensively assessed using geographic, economic constraints, wave condition and wind resource factors, but the focus of this paper was on the geographic constraints and wave conditions. Imjado had several geographical constraints, despite having a good wind power density, while Saemangeum had a relatively low wave height, shallow water depth, close substation and slow tidal current. It is anticipating that the present comparison and analysis could be used as reference guidelines when selecting and preparing the design of large-scale offshore wind farm in the near future.

As the importance of renewable energy diffusion spreads, promotion of sustainable renewable energy projects such as agrivoltaics is expected to accelerate. Furthermore, to promote agrivoltaics projects, it must be considered the legislation related to agrivoltaics and Chungnam Province's local policy. This research focuses on the selection of the most suitable sites for agrivoltaics installations in Chungnam Province in South Korea. Therefore, the process of this research was as follows. First, the legislation related to agrivoltaics and local policy in Chungnam Province were identified. Second, it employs an analytic hierarchy process (AHP) to consider important criteria and their weights for site selection. Third, based on the weights calculated AHP, geographic information system (GIS) was performed to select most suitable location selection of agrivoltaics installations in Chungnam Province. The analysis identified approximately 60 promising most suitable location for agrivoltaics installations in Chungnam Province, primarily in the northern part of Chungnam Province. These areas are expected to meet electricity demands in nearby regions since these are relatively adjacent to Gyeonggi Province. According to the results of research, policy suggestions related to agrivoltaics were presented separately into the agricultural sector and the electricity power sector. The study's results serve as a valuable resource for future national-level candidate site selection for agrivoltaics projects.

The GIS(Geographic Information System) projects require big initial investment and cost of maintenance. Decision makers would not launch GIS projects unless they are convinced of the benefits of the projects. Therefore the purpose of this paper is to develop an appropriate model for GIS project evaluation. We proposed a GIS project evaluation model and summarize the steps involved in Cost-Benefit Analysis(CBA). The costs of a GIS implementation include hardware and software cost, costs of database development, training expenses, annual maintenance expenses, and other annual expenses. The benefit by using GIS has been assessed into Type I(direct benefits), Type II(indirect benefits), Type III(benefits that result from the sale of information services), Type IV(intangible benefits).

The Construction Project Information System(CPIS), an information system constructed as part of the Construction Continuous Acquisition & Life-cycle Support(CALS) of the Ministry of Land, Infrastructure, and Transport(MOLIT), is designed to digitize construction projects across all stages, and enable sharing of information so as to enhance the productivity and efficiency of construction projects and secure their transparent administration. One of MOLIT's internal work systems, CPIS focuses on work-handling and data management. However, now over 10 years old after its construction, it focuses on text and document-based construction project information, but it cannot be interfaced with the visualization-based GIS, which limits the sharing and dissemination of information and the determination of the overall construction project status. To resolve the existing CPIS limitations and problems and to upgrade the system, this study examined domestic and overseas GIS technology trends and relevant information systems, and analyzed the CPIS status and problems. It thus proposed total GIS application measures to upgrade CPIS. Also, it identified detailed CPIS utilization measures and GIS application measures by unit system, and analyzed considerations for GIS application.

The purpose of this paper is to search for the construction of UDS(Urban Diagnosis System) which can be effectively applied to selecting or classifying the districts for carving out projects of urban planning based on urban geographic information. In order to promote projects of urban planning, it is essential that selecting or classifying the urban districts should be precisely diagnosed according to the respective blocks. Objective measuring standards are needed for this, and the UDS can be applied to analyzing these standards according to the levels. With these in mind, this paper will consider the present states of Korea and the established states of developed countries. Besides, the interest of this paper is to seek the ways of utilizing GIS most effectively in the urban planning areas and application methods. Also, it will find the ways of applying UDS extensively to selecting or classifying districts far the purpose of carrying out urban planning projects actually in the case areas.

Since the National Geographic Information System(NGIS) project of 1995, the geographic information projects have been promoted in various areas such as central and local governments. In the fact that large scale budget has been invested to geographic information projects as a national policy, the cost-benefit analysis would be essential to enhance the efficiency of the resource allocation. In this circumstance, this study analyzes the costs and benefits of geographic information produced by NGI(National Geography Institute). As a result of the cost-benefit analysis, the total amount of benefits were estimated approximately 620 million dollars and the accumulated ratio of the cost to benefit was 1 to 4.4. Also, the internal ratio of the benefit was 38%, which justified the large scale investment. In case of adding qualitative benefits which can not be measured in a quantitative term, the overall benefits from using such geographic information would be much higher than quantitative benefits. Further research work is required for more objective verification of the large scale national project such as building nationwide geographic information.

NGIS projects have been widely proceeded by the central and municipal governments, and the higher cost for proceeding the NGIS projects emphasizes the importance of the data sharing among related agencies. For supporting data sharing, effective data generation, and management. 'THE GUIDELINE FOR MANAGING AND DOCUMENTING GEOGRAPHIC INFORMATION CATALOGUES' has been established and enforced since the year 2002. Although metadata for distributing geographic information through the NGIS distribution network has already been installed, this needs to be complimented to maximize the data utilization. Based on such requirements, a draft standard of the national metadata which is compliant with the ISO 19115 has been proposed from this study. All components of the metadata for distributing geographic information have been included and related metadata items for the management purpose have been derived from domestic and foreign studies. Based on this, draft national metadata standards comprised of 13 sections have been made. The metadata standards from this study could contribute to building basic standards to access and to utilize geographic information in various application field. This would also be fundamental base for activating GIS in public and private sectors.

The diversification of the New Deal urban regeneration projects, that started in 2017 in accordance with the "Special Act on Urban Regeneration Activation and Support", generated the increased demand for the accuracy of data-driven diagnosis and project type forecast. Thus, this research was conducted to develop an application model able to identify the most appropriate New Deal project type for "eup", "myeon" and "dong" across the country. Data for application model development were collected through Statistical geographic information service(SGIS) and the 'Urban Regeneration Comprehensive Information Open System' of the Urban Regeneration Information System, and data for the analysis model was constructed through data pre-processing. Four models were derived and simulations were performed through polynomial regression analysis and multinomial logistic regression analysis for the application of the appropriate New Deal project type. I verified the applicability and validity of the four models by the comparative analysis of spatial distribution of the previously selected New Deal projects by targeting the sites located in Seoul by each model and the result showed that the DI-54 model had the highest concordance rate.
