A lot of GIS DB in Korea is distributed and integration for decision making is difficult. Therefore, the SDW is needed to improve the problems and enhance efficiency. The SDW is used for making decisions about various problems by integrating scattered spatial information. This study analyzes business activity of a local government and plan the data cube to implement spatial OLAP for an efficient decision making.

Recent emergence of spatial big data attracts the attention of various research groups. This paper analyzes the research trend on spatial big data by text mining the related Scopus DB. We apply topic model and network analysis to the extracted abstracts of articles related to spatial big data. It was observed that optics, astronomy, and computer science are the major areas of spatial big data analysis. The major topics discovered from the articles are related to mobile/cloud/smart service of spatial big data in urban setting. Trends of discovered topics are provided over periods along with the results of topic network. We expect that uncovered areas of spatial big data research can be further explored.

This study conducted an analysis of the distribution and status of baby boomer households and trends of turn to farming and returning home. At the same time, the density analysis of land price increase data, building data, and floating population data was conducted in Jeollanam-do County. The established base areas were superimposed to distinguish the regional centers according to the number of superimposed indicators. It is intended to present management measures according to the degree of activation of the center. An area where three bases overlap can be designated as a center activation area, and a place where two regions overlap can be designated as a center semi-activation area. Using the analysis of regional centers at the county level, hierarchies of the centers were classified and management measures were presented. Based on these findings, this study addresses meaningful applicability for regional and medium- and long-term plans.

As the results of the information project, manufacturing of the digital map and various thematic maps of the national land has been completed. Furthermore, it is necessary to organize a systemized management system, which can control and utilize all artificial features (e.g. buildings, roads, bridges etc.) as well as natural geographic features (e.g. rivers etc). Howener, it has difficulties in managing NGIS as a unified system, because of the discordance of DB of each geographic management organizations. Therefore, this study has been conducted to apply to the system and method providing geographic UFID that can be a key in order to managing, searching and utilizing geographic and artificial features and that makes it be able to estimate the location with the only identifier. Moreover, the system and method, providing geographic UFID, applies to systemized management of NGIS DB as well as consistency of information.

Looking at the changes in the earthquake of 33 years of South Korea, earthquake in the magnitude of 3.0 or stronger have been conducted about nine times a year on average, and the epicenter of the earthquake is moving towards the inland from the coast. As the possibility of earthquakes increase, it is time to require utilization of underground space integrated information for earthquake disaster prevention. But, now the data related to the characterization of the ground and geology in the areas weak against earthquakes is insufficient, so we need to collect new geology and the ground survey data on nationwide scale and have to establish earthquake disaster prevention plans through the joint use of the existing underground space information. In this study, we determined the scope of construction of underground space DB information that is needed for earthquake disaster prevention, presented the construction plan of DB static and dynamic information of underground space. It also suggested the utilization of underground space scheme information for built earthquake disaster prevention. The underground space information for earthquake disaster prevention that was built through determining the scope and constructing, planning the utilization of underground space information is supposed to used as DB of the integrated management system of underground space and steep slopes information for steep slopes and earthquake prevention by Emergency Management Agency.

XML is normalized text form that is designed to transmit structured document in web as that propose in W3C (World Wide Web Consortium) in 1996. Function that this can overcome HTML's limit that use in existing in Internet and user define new tag to HTML by way to solve SGML's complexity added. There is many efforts to use storing this XML document in RDBMS but to relation style DB because XML document is tree structure structurally data SQL and perfect disaster caused by things that is language to ask a question accomplish XQuery that so it is W3C's XML standard query appear. After store XML informations including space information to RDBMS in this paper, Spatial XQuery through converter that is Sqatial XQuery2SQL through Spatial operator, Spatial function SQL of by Sqatial XQuery2SQL conversion algorithm that draw information in RDBMS after change embody wish to.

현재 서울시 내에는 수많은 공공조형예술품들이 있다. 하지만 시민들은 그것들이 어디에 위치하고 있는지 쉽게 파악 할 수 없는 실정이며, 그에 따라 공공조형예술품들을 즐길 기회 또한 잃고 있다. 그래서 Web2.0 및 Mash-Up을 활용한 Web Portal Site를 구축하여 그것들에 대한 위치정보를 제공해 줄 뿐만 아니라, 시인들의 의견을 수렴하여 관리 및 유지보수 측면 등의 의사결정에 직접적으로 참여할 수 있는 Web 공간을 구축하였다. 기본적으로 서울시에서 파악하고 있는 공공조형예술품들에 대한 DB를 제공하고 또한 사용자가 정보를 입력하는 인터페이스를 통하여 기존 DB에 없는 정보를 추가함으로써 관리자 및 사용자가 쌍방향으로 DB를 구축하게 된다. DB를 바탕으로 Naver Map 및 Google Map 을 활용한 공공조형예술품들의 위치를 나타내는 지도를 제공한다. 그리고 입력된 DB를 바탕으로 예술품들의 행정구역별 수량 및 각 예술품 종류별 수량 등의 통계적 자료를 추출하여 제시하고, 사용자는 입력되어 있는 예술품들에 대한 평가 및 관리 보수 등의 의견을 제시하여 서울시 내의 공공조형예술품에 관한 의사결정에 의견을 제시할 수 있다. 본 연구물의 결과로 기대 할 수 있는 효과는 도시 재생 및 도시 계획 재정립에 있어 사용자 참여 유도 및 참고적 역할을 할 수 있고, 도시 내 조형예술품들에 대한 정보 제공의 기점 역할을 하여, 관광객 유치 및 도시 문화사업의 도움이 될 수 있다.

With the development of GeoWeb technology, 2D/3D spatial information services through the web are also has been used increasingly in the application of disaster management. This paper is suggested to construct a web-based 3D geo-spatial information mapping platform to visualize various spatial information collected at the disaster site in a web environment. This paper is presented a web-based geo-spatial information mapping service plan for the various types of 2D/3D spatial data and large-volume LiDAR point cloud data collected at the disaster accident site using HTML5/WebGL, web development standard technology and open source. Firstly, the collected disaster site survey 2D data is constructed as a spatial DB using GeoServer's WMS service and PostGIS provided an open source and rendered in a web environment. Secondly, in order to efficiently render large-capacity 3D point cloud data in a web environment, a Potree algorithm is applied to simplifies point cloud data into 2D tiles using a multi-resolution octree structure. Lastly, OpenLayers3 based 3D web mapping pilot system is developed for web visualization of 2D/3D spatial information by implementing basic and application functions for controlling and measuring 3D maps with Graphic User Interface (GUI). For the further research, it is expected that various 2D survey data and various spatial image information of a disaster site can be used for scientific investigation and analysis of disaster accidents by overlaying and visualizing them on a built web-based 3D geo-spatial information system.
