참여와 공유 개방을 모토로 하는 Web 2.0이 GIS 기술과 접목되면서 GIS 분야에서의 새로운 패러다임으로 제시되고 있는 것이 Where2.0이다. Where2.0은 지리정보와 시맨틱웹을 연동하는 새로운 패러다임으로 Google의 Google Map이나 Microsoft의 Virtual Earth에서처럼 '나만의 지도'라는 새로운 비즈니스 및 서비스 모델이 각광을 받고 있다. GIS 시장적 측면에서 보면 Where 2.0 패러다임의 확산은 전문가 중심(Doer)의 GIS에서 일반사용자 중심(Viewer)의 GIS 시장의 확대로 나타나고 있으며, 비즈니스지원시장과 개인생산성 시장이 지속적으로 확대될 것으로 전망되고 있다[IDC2004]. 이에 본 고에서는 최근 이슈로 대두되고 있는 Geospatial Web의 기술적 동향을 살펴보고, 새로운 GIS 패러다임 속에서 보다 효과적인 지리정보 서비스를 제공할 수 있는 맞춤형 지리정보 제공 서비스 개념 및 모델을 제시하도록 한다.

The purpose of this study is to design the GIS (Geographic Information System)-based BIM (Building Information Modeling) Objects Visualization System (OVS) Architecture by using Open source BIM Server Cost-Effectively. Recently, the studies related to the facility management using GIS and BIM are being researched world-widely. In this studies, it's important to develop the BIM Server to link the heterogeneous system such as GIS and represent GIS-based BIM objects. To implement it, the trends in related studies were reviewed and the open source-based BIM server architecture was analyzed. And then the architecture considering the BIM server was designed to represent the geometry and property of the BIM object which was stored in BIM server. Lastly, the system by using the proposed architecture was developed.

This article reviewed issues in Korean geographical journals: web GIS and National GIS. Web GIS in Korea is now evolving to mobile GIS, which requires portable hardware, wireless Internet, and GPS receiver. The new trend of mobile GIS is using a smart phone. Recently, a variety of studies for the mobile App and mobile Web in Korea has been developed. With explosive information on the Web 2.0, the Korean government has built the Human-Oriented Geographic Information System (HOGIS) in which Ontology was implemented for semantic query on the Web. On the government side, Korean government has produced various nationwide data through 4-phase NGIS project. Current NGIS ($4^{th}$ phase: 2011-2015) moves toward a Korean Green Geospatial Society using geospatial information as a new growth engine for the future.

This study proposes a framework of a GIS service network to connect local governments'Land Management Information Systems(LMIS) together. Databases constructed far LMIS's are very crucial information on both administrative business and civil affairs administration. However, they did not give full play to their values because they could not be shared sufficiently. Local governments build their databases individually using diverse GIS solutions. It causes some problems on sharing them. To demonstrate their geniuses, they should be connected to each other within a network for the whole country, and are served whenever and wherever to people who require them. for this, there are two main problems to be solved. Firstly, a GIS service network that handles heterogeneous and distributed computing environments is organized to link every LMIS each other by the GIS service network vertically and horizontally. Secondly, a mechanism should be developed to access the GIS service network readily and to search GIS data efficiently. The needs from every types of user should be satisfied by the mechanism. As the result of investigation of the issues, one of the most possible solution was suggested in this study, which is a Web based approach. To take into account the advance of information technology in the future and the requirements of e-government, stepwise strategies that integrate the LMIS's into a Web based system was recommended.

This study applied SWAT model to analyze suspended sediment load that is influence on the high density turbid water in Donghyang and Cheoncheon basin, which are located in the upstream of Yongdam Dam. GIS data such as DEM, land cover map and soil map, and meteorological data were used as the input data of SWAT model. And the rating curve equation and Q-SS equation of Donghyang and Cheoncheon gauge station were applied as the measured values of them. As the result of flowout, the coefficient of determination ($R^2$) and the Nash-Sutcliffe coefficient of efficiency (EI) of model calibration showed high as 0.87 and 0.87 at Donghyang gauge station, and the $R^2$ and EI of model validation were high as 0.95 at Cheoncheon gauge station. Also, as the result of suspended sediment load, the $R^2$ and EI of model calibration were high as 0.77 and 0.76 at Donghyang gauge station, and the $R^2$ and EI of model validation marked high as 0.867 and 0.80 at Cheoncheon gauge station. It is considered that the suspended sediment load of 2003 showed the highest due to rainfall amounts and rainfall intensity in using SWAT model. The results of suspended sediment modeled in this study can be applied to the decision-making support data for the evaluation of soil erosion possibility and turbid water potential in the management of reservoir.

In this research, a ubiquitous-based strategy for managing waterworks facilities is proposed to increase the usability of the existing related databases and to ensure the systematic way of distributing information. The current status of the existing waterworks GIS and GIS database were analyzed to achieve the goal. By studying the state-of-the-art technology, we found that importing the LBS(Location Based Service) technology to the databases is necessary. The results of these efforts are exclusive waterworks-mobile-terminals and LBS system supporting them. Furthermore, the applicability of the ubiquitous technology to waterworks has been examined to realize the real-time waterworks management.

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 role of a GIS as a tool for a national information infrastructure can best be fulfilled once GIS standards are implemented. In this paper, we have identified what the contents of GIS standards in other countries are, and what should be the future direction for implementing a nation's GIS standards. Based on a detailed review on GIS standards in the USA, Australia, Japan and the United Kingdom, we derived the following: (1) A nations's GIS standards should include both geographic information content standards and geographic information service standards: (2) A nation's GIS standards should be a profile of ISO GIS standards: (3) Each GIS standards should be developed on the bassis of the Entity-Relationship Model using Unified Modeling Language: and (4) Experts in GIS should pay much more attention on studies on GIS service standardization. As for building the national GIS Standards for Korea, we recommend both GIS Content Standards and GIS Service Standards be simultaneously developed. GIS Content Standards include geographic feature content standard, feature classification standard, portrayal standard, rules for application standards, spatial reference model and terminology. GIS Service Standards include standards for data sharing such as metadata standard and transfer standard, quality standard, quality principle and portrayal standards.
