SWAT includes a lot of parameters related with geography, hydrological time series, land management and water pollution, etc. So, it needs many spatial, non-spatial and time series data to run SWAT. If SWAT is operated in conjunction with GIS, we can use database which includes model input data and do all the processes which covers data creation, model input and analysis of simulation results in a system. The objective of this study is to develop HyGIS-SWAT which is the interface system to couple the SWAT model and HyGIS. To achieve this object, system operation process based on HyGIS-SWAT data model is evaluated and databases are designed and established. As a result, HyGIS-SWAT prototype system is developed. HyGIS data model and HyGIS-Model operation process can be applied effectively to the development of HyGIS-SWAT. The technologies from this study can be used as base technology to develop another HyGIS application which connect HyGIS with models.

본 논문의 목적은 GIS특성이 반영되고 표준화를 적극 활용한 GIS 감리중점사항을 제시하는데 있다. 이를 위해 GIS를 정보시스템의 한 분야로 간주하여 정보시스템의 개발과정의 단계를 살펴본 후에 GIS의 데이터제작단계를 추가하여 GIS 감리중점사항을 제안하였다. 감리중점사항의 제시를 위해 GIS 감리에 관련된 기존연구와 감리사례별 연구를 통해 감리중점분야를 도출하여 각 분야의 중점감리사항을 제시하였다. 특히 현재 국내에 제정된 표준화목록을 대상으로 각각의 표준화를 분석, 정리하여 표준화 부분의 감리중점사항으로 제시하였다. 따라서 본 연구결과를 GIS 감리업무 종사자가 작업지침의 일부로 활용함으로써 감리수행 활동이 적절히 진행되고 있는지를 확인할 수 있고 궁극적으로 GIS 활용시스템의 효율성, 안전성, 확장성 등의 확보에 기여하리라 사료된다.

Specially, location information can say that is important information in this ubiquitous environment and solutions of new GIS system to utilize this are required. Examine method to improve web geography information service system because this paper uses XML and presented specific implementation result. Through internet. it planed various geography information that offer in form of service that do not receive restriction of heterogeneous system environment. Also, did thing that is easy when request service about geography information that user need and deliver fast by purpose. Supplement and to improve open-ended and XML of form normalized use and developed existent web geography information service. So that can use map service in web browser without setup of application program that buy expensive GIS software or offer in each company design and implement.

With the rapid growth of the Internet geographic information services through the WWW such as a location-based service and so on. Web GISs (Geographic Information Systems) have also come to be a cluster-based architecture like most other information systems. That is, in order to guarntee high quality of geographic information service without regard to the rapid growth of the number of users, web GISs need cluster-based architecture that will be cost-effective and have high availability and scalability. This paper proposes the design of the cluster-based web GIS with high availability and scalability. For this, each node within a cluster-based web GIS consists of main memory spatial databases which accomplish role of caching by using data declustering and the locality of spatial query. Not only simple region queries but also the proposed system processed spatial join queries effectively. Compare to the existing method. Parallel R-tree spatial join for a shared-Nothing architecture, the result of simulation experiments represents that the proposed spatial join method achieves improvement of performance respectively 23% and 30% as data quantity and nodes of cluster become large.

The advantages of using components result from their reusability between applications. Applications can be easily implemented by adding components. In this paper, we described the design and implementation process of ASC(Application Service Component) for component-based GIS applications. In our project, there are 5 applications : Road Facility Management, Urban Planning, Cadastral Map Management, Water Supply Management, and Sewerage Management. All of them use MapBase component which supports common GIS functionality. Although they are different applications, some parts of them are same. We analyzed the developed results in 1st and 2nd year, and the achievement of UIS(Urban Information System) project in Busan Metro City in Korea. The UIS of Busan was consisted of 5 applications to equal with our project. Then, we extracted 11 common used components between 5 applications, and implemented 5 common components of them and 2 additional components. They were Authority, GISReport, IndexMap, Measurement, Search, Symbol Manager, and Attribute Display. As we offered them to companies developing application components, they were able to reduce the development time.

지리정보시스템을 이용한 사면붕괴 연구는 국내외 많은 연구논문과 보고서를 통하여 보고되어 왔다. 반면, 지리정보시스템을 이용한 연구는 현재 다수의 학자들에 의하여 발표되고 있으나, 그 결과에 대한 비교와 국내 실효성에 대하여 언급한 논문은 다소 미흡하다. 본 논문에서는 국내 자료의 실용가능성을 감안하여 사면붕괴지역 가능성예측 산정 모델 중 두 가지 방법, 이변량 통계분석과 결정론적 분석을 통하여 동일지역에 적용하여 그 결과를 비교하였다. 선정된 대상지역은 2002년 태풍 '루사'로 인하여 피해가 규모가 큰 강원도 강릉시이고, 두 모델을 이 지역에 적용하였다. 결과 비교는 동일지역에 동일 자료를 사용하더라도 모델에 따라 발생가능성이 높은 지역이 다소 차이를 보였으며, 모델 또한 자료의 질적, 양적인 성질에 따라 크게 영향을 받는 것이 밝혀졌다.는 것이 밝혀졌다.

지리정보시스템에서 사용되는 공간데이터의 특성은 양이 방대하고 구조가 복잡하여 데이터를 구축하는데 많은 비용과 노력이 요구된다. 또한 각 지리정보 응용시스템마다 특정한 포맷으로 데이터를 구축, 사용하는 실정 때문에 여러 가지 공간데이터 포맷이 존재하고 사용하는 방법이 다양하다. 그러므로 여러 포맷의 공간데이터를 이용하고자 하는 사용자는 해당 데이터 포맷들을 모두 알아야 하고, 포맷뿐만 아니라 사용자의 시스템이 공간데이터서버의 환경에 밀접하게 의존적이다. 본 논문에서는 다양한 공간데이터 포맷의 공간데이터서버에 접근하기 위한 통일된 접근 방법과 사용자가 상대 공간데이터서버의 환경에 독립적으로 서비스를 받을 수 있는 모델을 제안하고 실제 시스템으로 구현하였다.

Response of buildings under seismic load is different according to fundamental period. It is provided in Korean Building Code(KBC2009) seismic response coefficient by fundamental period for seismic design of buildings. Recently, many researchers have studied on fundamental period and seismic response coefficient. However, studies on seismic design using Geographic Information System(GIS) are not sufficient. Therefore, this paper has analyzed on seismic response coefficient of buildings using ArcGIS. This paper can be evaluated efficiently for seismic analysis of structures. And this study will be used as basics of a reasonable seismic design using Geographic Information Systems(GIS).

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.
