摘要：GeoStar is the registered trademark of GIS software made by WTUSM in China. By means of GeoStar, multi-scale images, DEMs, graphics and attributes integrated very large seamless databases can be created, and the multi- dimensional dynamic visualization and informatio n extraction are also available. This paper introduces the fundamental characteristics of such huge integrated databases, for instance the data models, database structures and the spatial index strategies. At last, the typical applications of GeoStar for a few pilot projects like the Shanghai CyberCity and the Guangdong provincial spatial data infrastructure (SDI) are illustrated and several concluding remarks are stressed
