Nowadays, the importance of safety monitoring for facilities is increasing. Therefore, the introduction of ubiquitous technology to replace the existing manually-operated methods is required. In this study, a web-based GIS system that provides monitoring information of bridges in real-time for the application of a bridge management system through the use of ubiquitous technology is constructed. Particular attention is given to the effective interconnection of bridge monitoring information and bridge management system and, through a ubiquitous environment, how to connect this with the UFID and the GIS-based bridge management system (BMS) operated by the Ministry of Construction and Transportation. In addition, data expression methods are also suggested that state the detailed locations and attributes of structures in bridge management by using GIS.

This paper demonstrates the prototype implementation of existing GIS operations using an integrated CA-GIS system where a CA simulator serve an analytical engine for GIS and compares the performance of the operations implemented here with the original ones. In addition, some new GIS operations that are not available in contemporary GIS are implemented and tested within the integrated system. It has shown that most of the local and focal operations were successfully implemented with CA-GIS and some operations written with the CA simulator showed better performance. New types of operations such as various shape filters, time-series filter, and diffusion operators were able to be implemented using the CA-GIS, which appears to be significant to enhance deficient analytical capabilities of contemporary GIS.

With the development and invention of computer and internet, GIS (Geographic Information System) has provided diverse services to users. Web 2.0, the next generation web, has been developed to create a new business by accumulating and structuring information from many users. The characteristics of Web 2.0 are blog, longtail distribution, SNS, DCC, collective intelligence, and so on. This study proposes a GIS 2.0 service model to maximize the introduction effect and use of GIS by the method that two-way communication and the participation of consumer, characteristics of Web 2.0, are used to build more practical GIS rather than providing spatial information in one-way and simple inquiry oriented way.

Although GIS technology has been developed rapidly, the education system for GIS technology and its utilization has not been well facilitated in our society. Consequently, the economic value in GIS application system is not estimated properly in the public sector. On the other hand, industries currently suffer lack of technocrats or researchers to develop GIS. In addition, the demand for GIS education on its concept and know-how has increased drastically as GIS analytic technology has come to be applied to more varified fields. Under these circumstances, this study researched and analyzed the current state of GIS education in the public, private and academic sectors in Korea. Furthermore, it recommended improving the educational environment for GIS experts training based on the results of the questionnaire used in the survey. Most of all, the national investment should be conducted systematically in order to improve quality of education in the public, private and academic sectors.

In this paper, we describe the implementation of a monitoring and diagnostic system for GIS. This system monitors operation status of GIS and transmits data from GIS to host. With this system, an operator can monitor an operating condition and judge the aging of each device, and prevent the failure or breakdown in advance.

최근 들어 웹기반 GIS 시스템에 대한 요구가 늘어나고 있다. 이를 만족시키기 위해 관련 시스템 개발에 대한 연구가 많이 진행되고 있다. 그러나 웹 기반이라는 제약 때문에 대용량 데이터를 이용한 GIS 표출은 한계에 다다르고 있다. 본 논문에서는 위치 정보를 압축하여 웹기반 GIS 시스템의 제약을 줄일 수 있는 알고리즘을 제안하려 한다. 제시된 기법은 웹기반 GIS 시스템은 물론 다양한 모바일 및 웹 그래픽스 분야에 응용될 것으로 예상된다.

We describes functions, design, and implementation of Awarematics/WMSServer in this paper. Awarematics/WMSServer is a open-source web map service server developed Kunsan National University and National Information Agency(NIA). Recently in GIS areas, It tends to increase System Construction which developed by using Open-source GIS, but we have not developed yet ourself-made Open-source GIS Engine in Korea. This paper describes function, design, and implementation of Awarematics/WMSServer serviced and developed by NIA and Kunsan Natioanl University.

The purpose of this study is to develop a dynamic DSS (Decision Support System) interfaced with GIS (Geographic Information System) and agriculture information network, In this study, DSS was developed to assist services which required tremendous and real time data in national scale. The data transmitte'd from the local area by the agriculture network were stored in DBMS (Data Base Management System) and analyzed by GIS. GIS and database tools used in this study were ARC/INFO 7.1.1 and INFORMIX 4.0. ACSAS (Agriculture Calamity Service Asist System) by the system prototype was constructed to solve the problem about the drought counterplan service which was to take the responsibility in the Ministry of Agriculture. It was easy to transfer, process, and analyze the information using the system. Specially, the meteological, the reservoir storage rate and the drought counterplan information were spatially analyzed by the functions of GIS.
