Abstract:In order to promote the standardization of China Groundwater Information System, cooperation has been carried out in China and Netherlands. Setting Jinan city as an demonstration area, introducing ReGIS information system, ReGISChina hydrogeological information system has been developed. Main functions of this system includes any geological sections, generation of threedimensional geological map, correction of database, chemical information analysis, generation of dynamic curve of water level, and the input, graphics generation and partition evaluation of the GMS model grid. It will lay the foundation for building a nationwide hydrogeological information system.
