摘要
目前,数字高程模型(DEM)在理论研究和实践应用方面都有了很大的进展,已在测绘、地质、农业、工程、建筑、军事、导航等多个领域得到了广泛应用,因此高效快捷地生产高精度的DEM是十分必要和迫切的。全数字摄影测量系统DEM生产方案是解决这一问题的有效途径,文章针对该系统的特点,提出了加强质量控制的策略和方法,并阐述了对一些实践问题的解决。
With the development of the computer technology and the need of national spatial database of basic geographic information, great progress is made in the theory research and practice application of DEM. At present, DEM has applied in many fields as mapping, geology, agriculture, engineering, architecture, military, navigation. So it is very necessary and imminence to acquire high precision DEM rapidly. Obviously,the VirtuoZO NT system is the best solution for working out the problem. The problem can be worked out by aiming at the specialty of the system and intensifying quality control.
