【Abstract】 The development of geoscientifical information system with GIS and data fusion techniques are studied in this paper. The authors developed a sophisticated geoscientifical information system of the land and resources of Hunan province with advanced software and hardware of the world class. Except for spatial informational query, system supplies all kinds of complex analysis features such as buffer analysis, overlay analysis, geomapping etc., which provided an important mean for the management of geoscientifical information of the land and resources of Hunan province, and also a new research idea for regional ore prediction.更多还原
