GIS can be used on almost entire fields of the world, such as the national land management, environmental management, disaster management, enterprise activities, and general lives. GIS is called as an infrastructure of the knowledge information on the cultural society. For insuring the national power on the periods of the unlimited competition, it is very important to establish the national information infrastructure. Purpose of the NGIS project I is to development on living benefits of peoplethrough an efficiency of policy and rationalism of planning. In order to achievement of this purpose, the NGIS project I has been established using the national geographic information base planning. The NGIS project I consists of the master management part, the geographic information part, the technique development part, the standardization part, and the land Information part. These five GIS project parts are operated by four governmental ministers and related institutions, such as minister of transportation and construction, minister of science and technology, minister of information and communication, minister of administrative and home affaires. The NGIS I project is to establishment of the nation spatial information systems, such as various nationwide digital maps, GIS technique development, GIS education, GIS standardization, and GIS researches.

지자체 GIS 정보화가 확산되어감에 따라 구축된 공간정보의 활용확산, 타 정보와의 연계 등의 요구가 증대되고 있으며 지자체 GIS 통합 연계는 지자체 정보화의 핵심으로 부각되고 있다. 그러나 많은 지자체에서는 도로, 상하수도 등 공간정보 수요가 높은 업무 분야를 중심으로 지자체 GIS 통합연계를 추진하고 있으며, 지자체 지리정보 담당부서의 중심으로 추진되고 있어 지자체 전 부서 대상의 공간정보 활용에 대한 한계가 있다. 이러한 한계를 극복하기 위해선 지자체 내 전부서에서의 공간정보 활용을 위한 지자체 GIS 통합연계 고도화 모델이 필요하다. 지자체 GIS 통합연계 고도화 모델은 지자체 지리 정보 담당부서 중심의 통합연계에서 확대하여 지자체 전 부서 및 국가적 차원에서의 협력체계를 고려한 모델로서 지자체의 수평적 수직적 통합연계 모델이다.

Web GIS (Geographic Information Systems) service systems provide the various GIS services of analyzing and displaying the spatial data with friendly user-interface. These services are expanding the business domain and many users want to access the distributed various spatial data. But, it is difficult to access diverse data sources because of different spatial data format and data access methods. In this paper, we design and implement web GIS services based on the inter-operability and GML (Geography Markup Language) of OGC(Open GIS Consortium) in web distributed environment. Inter-operability provides unique accessing method to distributed data sources based on OLE DB technology of Microsoft. In addition, GML support web GIS services based on XML. We design these GIS services as components using UML (Unified Modeling Language) of an object-oriented modeling language for specifying, visualizing, constructing, and documenting the artifacts of software system. In addition, they also were developed in object-oriented computing environment, and it provides the interoperability, language-independent, easy developing environment as well as re-usability.

GIS can supply large quantitiy of useful information about spacial relationship, consequently there exists great potential of GIS support ing for decision making strategies related to urban design and environmental planning. In different discipline areas there exist different information representation methods and considerations having direct or indirect relationship with spacial information, how to use GIS as a tool for facilitating the work in other discipline field, there are two basic questions crucial to the success of these interdiscipline applications. The first one is interoperatability among GIS and other applications, the second is the paradigm difference between GIS and other domain field regarding problem solving. In this paper, we investigate the spatial information of the urban environment provided in the analyses of the urban visual sustain ability, urban daylighting environment and urban wind environment. We also discuss the challenges and opportunities for cross-disciplinary GIS application regarding the aspect of Information Collection, Information Generation, Information Analysis and Information Visualization.

In AVL, GIS analyze the information from the vehicles to provide commercial or other value far user. As spatial analysis functions in GIS make a new valuable information using the vehicle's position and geographic object's location, they perform an important roles to improve the management efficiency of vehicles. Most GIS however are used static data for the spatial analysis, so the research area on AVL used dynamic vehicle location has generated unsuitable result. In this study, we use GPS real time tracking data to perform spatial analysis between moving vehicle and static geographic object. The method proposed in this paper considers the driving direction of vehicle and creates the result which is located in forward of vehicle. In this paper, two spatial analysis functions, near and connectivity, are developed.

By managing not only geographical information but also various kinds of attribute data. GIS presents useful information for decision-makings. Most of decision-making problems using GIS can be formulated into network-optimization problems. In this study we deal with the implementation of network optimization system that extracts data from the database in GIS. solves a network optimization problem and present optimal solutions through GIS' graphical user interface. We design a nitwork optimization system and present some implementation techniques by showing a prototype of the network optimization system. Our network optimization system consists of three components : the interface module for user and GIS the basic network the program module the advanced network optimization program module. To handle large-scale networks the program module including various techniques for large sparse networks is also considered, For the implementation of the network optimization system we consider two approaches : the method using script languages supported by GIS and the method using client tools of GIS. Finally some execution results displayed by the prototype version of network optimization system are given.

The objective of the paper is to recommend a database format of geographic informa¬tion systems for transportation (GIS-T) based on a review of geographic data files (GDF), a European standard format for navigation and the topologically integrated geographic encoding and referenc¬ing files (TIGER) if the USA The establishment of the standard format for transportation database is important for sharing data since data collection is costly. We believe the recommended format would reduce the implementation costs for GIS-T in Korea in the future.

최근 모바일 장치에서 GIS를 활용한 다양한 서비스 시스템들이 연구 개발되어지고 있다. 하지만 모바일 장치는 하드웨어 구성의 차이와 운영체제에 따른 제공 라이브러리의 차이가 심하다. 그래서 대부분의 서비스 시스템이 특정 모바일 장치에 제한적으로 설계 구현되어지고 있다. 본 연구에서는 기존 모바일 GIS엔진에서 디자인 요소와 같이 특정 모바일 장치에 제한적일 수밖에 없는 부분을 제외한 모바일 GIS엔진을 설계하였다. 그리고 모바일 GIS엔진의 구현은 C++표준 라이브러리와 추가 사용자 라이브러리를 이용하여 구현함으로써 이종 모바일 장치에 호환성 있는 모바일 GIS 엔진을 구현하였다. 또한 문자 인코딩 방식을 UTF-16으로 통일함으로써 문자처리에 대해서도 호환성을 유지할 수 있도록 구현하였다.
