To investigate the geo-environmental characteristics of Taitung County, the geographic information system (GIS) and remote sensing (RS) techology have been adopted to establish a database system that collects the geo-environmental data from the field investigations. All of the geo-environmental data collected by GPS are integrated with other database to form a complete database system for the county. The result can be displayed from the ArcView GIS system. This database system can simultaneously display data from caption image layers and attribute data. It is expected that the developed database system will be useful for the management and maintenance of Taitung city and the development of small areas in eastern Taiwan.
