伴随着我国国民经济建设的快速发展,根据需要有必要对现势性较差的1/万DLG地物数据进行更新。我们常用的1/万DLG地物数据更新方法比较繁琐,成本也较高,制作的周期也较长。因此在2004年我院探索了用最新DOM或无外业像控航测内业快速更新1/万DLG地物的可行性。本文将重点介绍这种更新方法的相关技术和精度统计。
As the national economy maintains a rapid development, it is necessary to improve and update the 1：10,000 DLG data of geographical object that is inferior, The method we commonly used is more complex, expensive and time-consuming. Therefore, our institute has done a feasibility study of quick-up dating with upto-date DOM or indoor aerial survey without outdoor photograph control, the following essay mainly focus on the related technology and precision statistics.
