摘要
主要对影像获取与处理、DEM精细化、自动解译技术应用和质检软件流程实现等地理国情普查关键技术的实现策略进行了论述,重点介绍了DEM精细化作业方法,并对比了几种自动解译软件的效率。研究结果表明,该方法能提高近30%的确工作效率。
This paper discussed the implementation strategy of geographical conditions census key techniques, such as images acquisition and processing, DEM refinement, automatic interpretation technology application and the quality software process implementation. And then, the paper introduced the work method of DEM refinement and compared the efficiency of several automatic interpretation softwares. The results show that this method can improve work efficiency 30%.
