Recently, the open source software market is becoming bigger and bigger as its demand keeps increasing worldwide. A variety of policies have been driven in Korea in order to vitalize the open source software. However, the performance for vitalizing the open source GIS software has not been initiated yet. The purpose of this research is to generate the support plan to vitalize the domestic open source GIS software which is appropriate for real field by analyzing the actual demand and user requirements. For this purpose we reviewed all the researches related to the vitalization of the open source software and conducted a survey based on the awareness of the open source GIS software, the current vitalization status, the adoption intent and necessary strategies for vitalization. According to the survey, the intent of adopting the open source GIS software is relatively high in both enterprises(97%) and universities(89%). On the other hand it is very low in public organizations(69%). As a result, the survey implies that more intense public relations are needed to escalate the awareness of the open source GIS software in the public organizations. In addition, the survey shows that both education and technology support are definitely needed as a strategies for the vitalization of the open source GIS software. We expect that this research can be utilized as a basic material for the policy making of the vitalization of the open source GIS software in Korea in the future.

지리정보시스템(GIS)의 구축은 활용범위를 점차 확대하여 지속적으로 추진되고 있으며, 이러한 시점에 효율적인 정보시스템 구축을 위하여 정보시스템 감리 의무화가 법제화 되었다. 그러나 일반 정보시스템 구축과는 그 특성을 달리하는 GIS 구축에 있어 동일한 감리기준으로 시행하게 됨에 따라 GIS 감리 효율성을 확보 하는데 어려움이 있었다. 본 논문에서는 효율적인 GIS 감리를 위하여 기본적으로 GIS 특성연구와 감리 의무화 법제화 이전 GIS 감리기준과 개발방법론 등의 연구를 통하여 GIS 감리 점검항목을 연구 도출 하여 제안하였다. 또한 제안한 점검항목에 대하여 실제 GIS 감리 사례와 비교를 통해 실효성 검증을 시도하였다.

This paper show about the possibility of practical application after building VR(virtual reality) data based on Airborne LiDAR data which determines complicated topography quickly for the 3D-GIS construction. In this paper, we collected Airborne LiDAR data, digital map, serial photo and a basic design. The results are expected some effective determination by 3D-GIS construction based on LiDAR data. Hereafter, because the research will be able to be given quickly topography information on ubiquitous environment the field of construction and GIS will be able to be helped.

Recently, various researches have been attempted to connect or integrate BIM handling construction data and GIS handling spatial data. However, it is hard to interoperate by integration between two data models because characteristics and domains of data models between BIM and GIS are very different. In this research, we propose the platform to secure efficient interoperability between BIM and GIS and define the component technologies and functions of the platform proposed in this research by analyzing the existing commercial softwares.

Recently, forest soil sediment disasters resulting from locally concentrated heavy rainfall have been occurring frequently in steep slope areas. The importance of landslide hazard map is emerging to analyze landslide vulnerable areas. This study was carried out to develop HyGIS-Landslide based on Hydro Geographic Information System in order to analyze forest soil sediment disaster in the mountainous river basin. HyGIS-Landslide is one of HyGIS components designed by considering the landslide hazard criteria of Korea Forest Service. It could show the distribution of landslide hazard areas after calculating the spatial data. In this system, the user could reset the weight of hazard criteria to reflect the regional characteristics of the landslide area. This component provided user interface that could make the latest spatial data available in the area of interest. HyGIS-Landslide could be applied to the surveyor's compensation score and it was possible to reflect the landslide risk exactly through it. Also, it could be used in topographic analysis techniques providing spatial analysis and making topographical parameters in HyGIS. Finally the accuracy could be acquired by calculating the landslide hazard grade map and landslide mapping data. This study applied HyGIS-Landslide at the Gangwon-do province sample site. As a result, HyGIS-Landslide could be applied to a decision support system searching for mountainous disaster risk region; it could be classified more effectively by re-weighting the landslide hazard criteria.

This study is analyzing what necessary law and institution is to solve various problem that is happened in process that execute the first$\sim$second National GIS Master Plan in the meantime at visual point that the second National GIS Master Plan(2001-2005) period is expired. Specially, it is that present what improvement direction of law and institution by each field is. Minimize of obstacle factors far National GIS Master Plan is purposeful during the third National GIS Master Plan period. To achieve study purpose, this study analyzes background of National GIS law and institution, objective, system. It is expected that of this article can contribute to the picture of National GIS law and institution.

The purpose of this study is to extract the main locational factors to affect the location of Convenience Stores (CVS) in Songpa Gu, Seoul by using Geographic Information Systems. The procedure of research has three steps. First, the spatial distribution of CVS in Korea is analyzed by the places and time. Second, the main locational factors to affect the location of CVS in Songpa Gu are extracted. Finally, the potential locational zones where are selected by extracted locational factors are compared with the actual distribution of CVS in Songpa Gu. The main locational factors to affect the location of CVS include factors of the numbers geocoding method in GIS, it can be idenified that the 58 stores are located in the potential locational zone. However, this study has limitation to extract potential locational zones in detail. There are still difficulties to collect appropriate data for land use buildings as well as data for consumer behavior and regional characteristics itself.

The purpose if the study is to apply GIS technique to sample area, Choensoo-Bay basin for an efficient and practical coastal zone management if pollution control. The basins, Unit if pollution control, are selected with qualitative analysis using DEM after considered river length, degree and area of basin through channel network analysis. Choensoo-Bay basin is divided with 6 zones to 33 subordinate zones. It is found to be a big difference of pollutant loads in each zone. The pollutant loads use to review for efficient zoning. And also the result apply to measurement of water quality and building for environmental infrastructure.
