For managing and analyzing effectively diverse and complicated environmental informations, informations should be built systematically, and techniques should be developed. Environmental Information System(EIS) is composed of environmental informations, GIS, and manpower. Recently it is applied to Environmental Impact Assessment and environmental management, etc.. For effective application, EIS techniques will be improved. This article has four components. First, it describes building of environmental information comprising geographic and attribute data using GIS in Chuncheon district. Second, it explains programming for effective information analysis and management using AML(Are Macro Language in ARC INFO). Third, it provides specific functional capabilities including suitability analysis. Based on these analysis, this study makes some examples for systematic analysis and management of environmental information using interactive system.

Environmental Impact Assessment System, ever since its enactment in Korea fourteen years ago, has been steadily improved by introduction and implementation of new concepts and methodologies which include Environmental Impact Statement(EIS) preparation technique, selection of environmental factors, and the like. However, current guideline requires that every EIS, regardless of the specifics of the project type or characteristics of the site, must evaluate and study for all twenty-two environmental factors as set forth in the regulation. The situation causes many undesirable problems like; lack of site specific evaluation in most EISs, over-sized EIS drafts, consuming too much time and costs for EIS preparation, and so on. The objectives of this study are: - To establish a set of criteria to classify the types of the projects in terms of features of the project content and the characteristics of the site area. - To establish a guideline for selecting major environmental factors of the project type criteria, and - To provide basic materials for the preparation of complets draft EIS of the Amendment of Environmental Impact Assessment Act.

The choice of economic development over environmental protection has been used to explain the decline in the quality of the environment in developing countries. The authors reject this explanation and propose a theory of negligence to explain this decline. They point to the advantages of environmental impact assessments in dealing with the problem of negligence and presents case studies from four countries. Organizational models for Environmental Impact Assessments in Developing Countries are proposed as useful policy measures.

This study conducted a visual impact assessment of an apartment complex project proposed in Jungkye-dong, Seoul. Three design alternatives of the project-alternatives 1, 2, and 3-which differed in form, color, scale, and arrangement of buildings were simulated with computer image processing technique. The simulations were presented to the public who were mainly residents in the project area, and visual impact resulted from the alternatives was assessed by them. Their responses were then statistically analyzed. It was found that, in terms of compatibility with the surrounding landscape, alternative 1 was the most favourable because it was more traditional, natural, and diverse than alternatives 2 and 3. At the same time, the alternative was most preferred by the public because it was more plain, natural, and diverse than other alternatives. It was suggested that the visual impact assessment with public participation conducted in this study would help both planners and the public to make more intelligent decisions.

환경영향평가과정과의 연계 속에서 지속 가능한 개발의 개념, 전개 유용성을 알아본다. 환경영향평가는 환경적이고, 경제적이고 사회적인 목표들의 필요성에 대한 균형을 유지하기 위하여 의사결정에 앞서서 예측되는 과정이라고 볼 수 있다. 이글은 어떻게 환경영향평가 과정이 사업단계에서 프로그램, 계획, 정책 단계로 전개되고 개선되는지를 보여준다. 환경영향평가과정을 누적적 영향, 문제중심의 환경영향평가, 정책, 환경계획 및 평가와의 연계에 초점을 맞춘 지속 가능한 개발을 운영하는데 기본체계를 제공할 수 있다. 지속 가능한 개발에 대한 설계적인 적용을 지원할 수 있는 실제적인 EIA도구와 방법들을 검토하고, 리우정상회담 후에 지금 일어나고 있는 후속조치의 토론과 제도적, 실제적, 혹은 정치적 단계에서 환경영향평가 과정이 핵심적으로 역할을 수행할 것을 제안한다.

GIS 기법을 이용한 환경영향평가 방법론을 설명한다. 도시(Kirovsk, Apaity, Murmank, 북극지역)에서의 생태적 갈등영역의 탐지에 대한 작가의 경험 뿐 아니라 모스크바 지역에서의 금속성 비료이용의 결과평가의 경험에 대한 특성을 단수하게 설명한다.

A Nationwide survey of ecosystem in the Republic of Korea was accomplished from 1986 to 1990 and in that survey, GIS and remote sensing were used partially. This was done by the Ministry of Environment(MOE), which introduced remote sensing and GIS for environment management in late 1980's. Especially the National Institute of Environmental Research (NIER) are under the research on systematization of environmental information with an ultimate goal of application of GIS and remote sensing to environmental impact assessment. Although the Korean peninsula is in a non-tropical zone, we introduce two case studies on remote sensing applications to ecosystem managements in the Republic of Korea. One is a study on change detection in urban vegetation of Seoul with Landsat data and the other is a study on detection of insect damaged pine tree area using Landsat TM data. The techniques involved and the conclusion from these studies were relevant to vegetation studies in tropical ecosystem.
