Environmental Information System is not a firmly established system. This field is new because theoretical framework for the system is developing in terms of concept and development methods. Many scholars through the world are trying to develop a complete Environmental Information System.
This research examines various Environmental Information Systems, and concerns DB construction and application programs, which are important to develop useful Environmental Information System. DB construction includes the classification of environmental information, the standardization of environmental data, data collection, and quality evaluation of DB. Application programs as well as DB construction are important because they help to choose best option using the DB. Developing application programs includes system construction based on new technology including GIS, environmental statistics, connection with established environmental modeling and system integration, and supporting policy decision through easy interface with users.
Although this research mainly focuses on the development of Environmental Information System using GIS, the direction of the research is toward developing policy decision making support system, which can be used for environmental policy making and enforcement.
