We have researched a character of BIM(Building Information Modeling) and GIS(Geographic Information System) data for integrated utilization of urban spatial data and building data for $CO_2$ reduction. We consider literature on integrated utilization of BIM and GIS and measure method of $CO_2$ in urban spatial unit. Among them without distortion of standard data structure, derive method how to install between BIM and GIS standard data. Rhino & Grasshopper is utilization tools of DB platform. The compatibility with existing BIM and GIS data format, graphic and numeric results can be output at the same time. And using the existing ARCHSIM, it can be easily combined for building energy analysis program. Based on BIM and GIS data to run an energy analysis target on Majang-dong, it could be poly synthetically derived the value information and graphic information.

최근 기후변화에 따른 생태계의 파괴, 해빙, 해수면 상승 등의 현상이 발생함에 따라 코펜하겐에서는 유엔기후변화협약 당사국 간의 온실가스 감축 논의를 위한 총회가 개최되는 등 전 세계적으로 기후변화에 대한 관심이 고조되고 있다. 국내에서는 기후변화가 지구환경시스템과 서로 밀접한 관계가 있음에 따라, 기후변화에 따른 환경의 변화를 함께 고려하는 연구가 진행되고 있다. 그러나 현재 기후-환경 통합 연구에 필요한 자료는 산재되어 있고, 필요한 자료의 확보에 많은 시간과 노력이 필요로 하기 때문에 원활한 연구 진행이 어려운 실정이다. 따라서 본 연구에서는 기후-환경 분야의 분석 지원을 위한 통합DB의 구축방안에 대해 연구하였다. 통합DB의 구축 시 발생하는 문제점에 대해 분석하고, GIS의 적용에 필요한 위치체계의 정의, 데이터 포맷에 따른 관리 방안과 통합 DB 구축을 위한 데이터 표준화 방법을 이용하여 GIS기반 기후 환경 통합DB 구축 방안에 대해 제시하였다. 본 논문을 통해 구축되는 통합DB는 기후-환경 데이터의 원활한 공유를 통해 기후 환경 상호작용의 분석 기반을 마련하고, GIS기반의 공간분석에 지원이 가능하리라 기대된다. 나아가 기후-환경 변화에 대한 분석, 모의를 통해 기후-환경 변화에 따른 대응 전략 수립이 가능할 것으로 사료된다.

This paper is focused on the spatial variability of measured strong motion data during earthquake and its relationship with the performance of water distribution pipelines and residential buildings. Analyses of strong motion and the correlations of peak ground velocity (PGV) and pipeline and building damage were conducted with a very large geographical information system (GIS) database including the relationship of time and earthquake intensity and the measured location, and Kriging spatial statistics. Kriging was used to develop regressions of pipeline repair rate (RR) and residential building damage ratio (DR) associated with $90\%$ confidence peak ground velocity (PGV). Such regressions using Kriging provide an explicit means of characterizing the uncertainty embodied in the strong motion data compared with other spacial statistics such as inverse distance method.

For expression of contour lines in mobile GIS environments, the client needs to receive the numerical data with the topographical map from a server. At this point, a client can't get the entire raw data because of the mobile characteristics. The approach to get representative points and to make isogram by interpolation methods, has some problems. The approach requires huge computing overhead at the client and doesn't guarantee the correctness of the isogram. In this paper, a data structure, algorithm and implementation results for efficient transmission of contour information to a client which is constructed from elevation information at a server, are proposed.

GIS based new postal marketing method is presented in this paper with spatiotemporal mining to cope with domestic mail volume decline and to strengthening competitiveness of postal business. Market segmentation technique for socialogy of population and spatiotemporal prediction of consumer propensity to purchase through spatiotemporal multi-dimensional analysis are suggested to provide meaningful and accurate marketing information with customers. Internal postal acceptance & external statistical data of local districts in the Seoul Metropolis are used for the evaluation of geo-lifestyle clustering and spatiotemporal cube mining. Successfully optimal 14 maketing clusters and spatiotemporal patterns are extracted for the prediction of consumer propensity to purchase.

Recently, interest of submarine mineral resources has been increasing from the depletion of land resources around the world and many countries are involving in submarine mineral resource exploration work. South Korea is also in progress of mineral exploration and relevant study to ensure the submarine mineral resources from around the Korean Peninsula. As a result, the submarine mineral resource exploration data have been increasing annually. A database and 2D GIS-based system have been constructed for the management of the data. However, submarine mineral resource exploration data is explored and created on the sea-bed. Consequently, the visual confirmation of the water levels and marine landform is important for high dimension analysis. Therefore, the major aims of this study are to collect marine landform data from around the Korean Peninsula and to develop 3 dimension GIS based system that is linked to the submarine mineral resource exploration data. In detail, marine landform data were acquired for the Korean Peninsula and they were interpolated into raster file format. The raster file was then processed to be easily used and was entered into an Oracle database. Based on this database, 3D expression and overlap function between marine landform data and submarine mineral resource exploration data were designed using ArcScene offered by the ESRI. After design, 3D GIS based expression system was developed. Confirmations of locations and changes in the submarine mineral resource exploration data based on 3D GIS are enabled to support the efficient application of the proposed system. It is expected that this system will be highly useful for estimating the reserves of mineral resources and for providing valuable information for economic evaluations.

Urbanization is worldwide phenomenon and unexceptional in Korea. It is necessary in the spatial decision making steps to predict urban forms for the efficient land use. This study aims to develop urban growth model based on allometry which deals with relationships between urban populations and urban area. For the input data and accuracy assessments, various GIS techniques are used. Although this research is an exemplary urban growth model dealing with physical data only, it can be a good start to develop a more practical model having socio-economic sides for planning practices.

In this paper, we carried out studying for real-time monitoring method about water distribution information of flow, flux, pressure and the vibrations, that facility management system checks it by using UFSN sensors. We developed UFSN sensing generator, gateway, and middleware, and defined UFSN sensing data format. Also we verified sending sensing data. We have monitored water distribution based on GIS drawing in real-time by storing sensing data in existing Underground Facility Management System.
