Environmental Information Systems have been characterized by typical expert systems in the past. In these days, public interest in the environmental condition has increased, which have evoked many information system on the net using geographic information system techniques. There are evaluation templates for web sites, but they are too general to apply to Environmental Information Systems (EIS). We designed a framework or a classification scheme for web-based EIS, especially for water quality and water quantity data. The criteria include a main function of web site, data level from the raw data to metadata, main presentation patterns(table, graph, map), temporal focus on the data (past, real-time, future), main variables for comparison (spatial, temporal, thematic) and map presentation skills from html tag method to wavelet engine. The designed pattern is applied to both international and domestic public web sites in Korea, with description on the synopsis of each site, good points and flaws. In addition, a simple questionnaire was given to public officers who are in charge of water quality control and data management in local governments. The designed classification framework is so flexible as to add an axis for more criteria and more points. This is a first trial for the classifications, so discussion on the appropriateness will be required. At this stage, the designed scheme will be utilized to analyze previous web sites which have many various purposes. Advanced techniques developed in the near future can be added to this scheme without much distortion
