摘　　要：控制点图形图像数据库的建立能够克服常规控制点获取技术中周期长、应用效率低、可重复利用率低的缺点,是实现高效、高精度几何纠正的基础。详细介绍了全国多级、多分辨率图形图像控制点数据库的数据源选择标准、控制点采集技术指标、数据库建立与管理模式、数据库共享机制等。最后对全国多级、多分辨率图形图像控制点数据库的应用做了简单介绍和展望。The advantage of creating the map and image database all over the world is that it can avoid the long cycle, low efficiency of application and re-use. The foundation of map and image database is the base of rectifying with high efficient and accuracy. It introduces the processing of building the Multi-level and Multi-resolution data base of image and map all over our country in this paper. Some technical including the standard of data source selecting and control points selecting, the model of database creating and managing, the method of database application and sharing , and the foreground of its application is also be talked about.
