Pilot Building of the Web-Bawed Information System for River Environmental and Ecological Information Thematic Maps

Currently, the government tries to improve the applicability of RIMGIS (River Information Management Geographic Information System). CS (Client Server)-based RIMGIS was replaced by Web-based RIMGIS, and various thematic maps were established to expand service function of RIMGIS. The objectives of this study were to construct database of river environmental and ecological information, and to produce 14 river environmental and ecological thematic maps, and finally to build web-based information reference system. River environmental and ecological information of water-related national project was categorized into 4 fields (biological, chemical and physical field) and the production processes of each thematic map were suggested. According to established data models of each thematic map and defined spatial/attributive layers, 35 web pages were designed.
