Abstract
We report on community environmental mapping through public participation using GIS and identify results and problems of this case study. Results of this case study show that community environmental maps are a useful tool to visualize and to share environmental information among participants; they became an environmental database for the area. Moreover, a user-friendly GIS was developed for easy operation of participants. They were able to operate the user-friendly GIS smoothly, although the GIS operation was difficult for general users. We were able to solve the problem by offering that technology. It will be necessary to consider social dimensions of the spread of GIS, to support system-making for technical co-operation, and to publicize it according to accumulation of data and access to it from the public.
