이 연구는 고등학교에서 GIS 교육의 현재와 발전 방향에 대하여 살펴보았다. 첫째, 최근 개편된 고등학교 교육과정에서는 GIS에 대한 내용과 비중이 늘어났으며, 이에 따라 GIS 교육에 대한 관심과 수요가 커지고 있다. 둘째, GIS 교육을 위한 GIS 교육 프로그램 개발이 시급한 상황이다. 교과 과정 설정에 부합되는 교육 프로그램과 제반 환경이 부족하여 교수-학습 현장에서의 GIS 교육이 활발히 진행되지 못하였다. 이에 본 연구는 기본적인 GIS 교육 프로그램을 제안하였다. 셋째, 향후 학교 교육에서 GIS 교육은 ‘GIS를 활용한 교육’과 ‘GIS에 대한 교육’의 통합이 바람직한 것으로 분석되었다. 정보화가 진행될수록 GIS 교육의 중요성이 높아지게 될 것이다. 현재 GIS 교육을 담당하고 있는 ‘지리’ 과목을 중심으로 이에 대한 체계적 준비와 연구가 필요하다.

제1차와 제2차 ‘국가지리정보체계(NGIS)구축기본계획’ 을 시행하면서 체계적인 GIS기반이 마련되어 중앙정부와 지방자치단체 등 공공부문을 중심으로 다양한 부문에서 GIS구축사업이 추진되었다. 그러나 GIS사업은 초기 막대한 구축비용과 사업완료이후에도 유지관리비용이 지속적으로 소요되기 때문에 그 타당성이 가시적으로 나타나지 않으면 사업의 추진이 어렵다. 따라서 본 연구에서는 체계적이고 과학적인 효과분석을 위한 GIS사업의 평가모형을 제시하고 이를 바탕으로 웹 기반의 GIS 효과분석시스템을 구현하였다. 본 연구의 GIS 효과분석시스템은 최신의 정확한 정보와 검증된 분석방법을 실시간 제공하기 위해 웹 기반으로 설 계 하였다. 왱 기반의 분석시스템은 GIS사업의 효과분석에 있어 시ㆍ공간의 제약을 받지 않고 GIS사업의 효과평가를 가능하게 한다. 또한 GIS사업의 효과측정에 있어서 타당성을 부여하여 과학적인 기준을 제시하며, 분석결과는 사업의 추진을 위한 재원마련과 정책결정자 설득의 기초 자료로 활용할 수 있을 것으로 사료된다.

Most advanced countries in GIS field have established and managed georeferenced socioeconomic data systematically and made a great profit on various social and economic areas. In Korea, however, socioeconomic geographical information is relatively poor compared to systems related to geographical and topographical features. This is mainly due to the characteristics of the process from the construction to the utilization of socioeconomic data. That is, from the stage of data construction, socioeconomic data require solutions for frequent changes compared to data on geographical and topographical features and, because of difficulties in marking the positions of individual entities, information is built up through setting appropriate spatial units of aggregation. In the stage of data utilization, the data often need to be combined with other types of socioeconomic data due to the complexity of socioeconomic phenomena. Thus, the this study examined usability of GIS in socioeconomic fields and the spatial dimension of socioeconomic information through representative cases of GIS in developed countries and, based on the results, derived data requirements for socioeconomic GIS found in the construction and utilization of data and proposed solutions for the requirements.

Recently, the geographic information system(GIS) is generally used in various fields with the development of information and communication technology, with expansion of its applications and utilization scope. Especially, utilizing GIS is expected to have positive effects on the geography learning and more helpful for the geographic information observation compared to the picture or 2D based media. The effective visualization of complex geographic data does not only take realization of its visual information but also increases the human ability in analysis and understanding to use the geographic information. In this paper, we examine a method to develop the geography learning contents based on the technology with augmented reality and GIS, and then we have a case study for various kinds of visualization techniques and examples to use in geography learning situation. Moreover, we introduce an example of the manufacturing process from the existing GIS data to augmented reality based geography learning system. From the above, we show that the usefulness of our method is applicable for effective visualization of the three-dimensional geographic information in the geography learning environment.

Effective data management of underground facilities is very important in terms of human life. For this, input of up-to-date and high-accuracy data should be preceded. Therefore, it is important to have an efficient data input method. In this study, by developing a sewage facility site survey program using open source software, paper drawings could be replaced with tablet PCs. By using a tablet PC, figures and property information acquired from the field are transmitted in real time through a database server. PostGIS query is developed to automate structured editing to minimize manual work in constructing a GIS (Geographic Information System) database for sewage facilities. did. In addition, the database was built using the sewage facility GIS database building program. As a result of comparing and analyzing the existing sewage facility database construction, work process, and work time, the work process was simplified and work time was shortened. In addition, through simple customization of open source software, it will be able to be used for field surveys and database construction in other fields.

The CBD(component based development) method has recently been on the rise as the main current among all fields of developing Information Systems. The developing system by building and integrating of components is encouraged in GIS sphere. Business domain which considerably identifies components occupies GIS shpere rather then any other sphere. Arithmetic function is quite needed in GIS sphere but non-arithmetic functions are also used in GIS sphere as well as in enterprise sphere. Component is characterized by ensuring the reuse of itself. The efficiency of reusing component is promoted as the component is functionally simple and is packed to a minimum. The GIS Component Extraction Method has already been presented in several studies but this study is about the GIS Component Extraction by the Affinity Analysis Method. CBD uses UML on a basis and the core of the UML is consisted of the use case and the class. The purpose of the Affinity Analysis is a study how relate between the use case and the class in a certain business domain and then the results identify the component. The Affinity Analysis is useful not only in GIS but also in every business domain and is considered to be popular as the procedure of this method is not complex at all.

The purpose of this study is to present the role of NGIS(National Geographic Information System) and the development strategy for Business GIS in the ubiquitous society. We analyze the level of GIS technology with the ICT(Information Communication Technology) as well as GIS application trends especially in location-based circumstances. Also, we advocate not only making GIS contents to meet the international standards such as GML(Geography Markup Language) and TPEG(Transport Protocol Experts Group) but applying GIS as a killer application to oncoming diverse ICT areas including LBS(Location -Based Service), Telematics, ITS(Intelligent Transport System), gCRM(geographic Customer Relationship Management), DMB(Digital Multimedia Broadcasting), u(ubiquitous)-City and u-Town. Finally, we build a conceptual Business GIS model based on NGIS for QoS, standardization, R&D, education, and security.

This research is primarily intended to develop a decision-making support system about the natural environment in the country by integrating various formats of spatial data into a comprehensive GIS database. The first part of the research is to design GIS database as a means of combining thematic cartographic data with field survey records. Ecosystem records acquired by a field sampling have been reproduced as digital thematic maps. The database also included various natural environment related data (map for forestry, soil, national park etc.) collected from many other agencies. The second part of the research is devoted to the design of efficient man-machine interfaces. A key concern in the GUI (graphic user interface) design process was to address the need to handle and to manage large databases by non-GIS experts. The system has been checked experimentally, enabled the users to quarry the data required simply and execute spatial analysis accommodating versatile alternatives in decision-making process. Detailed visual maps can be generated over large areas quickly and easily. The system will serve to increase the scientific and objective decision-making by overcoming serious constraints suffered from the past non-GIS-based approach. It is anticipated that this research output could be used as a valuable reference in building a nationwide natural environment GIS-DB (database) in the central and local governments.

GIS분야에 대한 다양한 연구가 진행됨에 따라 그 활용에 대한 관심도 확대되고 있다. Open GIS Consortium에서는 GML(Geography Markup Language)을 개발하여 이를 GIS 응용분야에 활용하고자 하는 연구가 활발히 진행되고 있다. GML데이터에서 의미 있는 정보를 추출하기 위해서는 데이터 마이닝 기법 활용이 필수적이다 최근에 데이터마이닝 기법 중 연관규칙을 이용한 탐색 방법이 제안되었다. 그러나 이 방법은 전체 데이터를 대상으로 의미 있는 정보를 탐색 하므로, 데이터 내에 포함되어 있는 부분 속성인 지리 공간적 연관성을 탐색하는데 한계를 가지고 있다. 따라서 녈 연구에서는 GML데이터에서 부분적 속성을 고려한 지역적 연관규칙 탐색 기법을 제안한다.
