| 摘 要： | 为缩短DLG成图周期,提高作业效率,采用基于自由网平差的一体化法进行DLG生产试验研究,并与传统法制作的DLG,在产品精度、生产工效和优缺点等方面进行对比。结果表明,基于自由网平差的一体化DLG生产法能较好地满足DLG生产精度要求,相比传统DLG制作,工期较短,作业效率明显提高,但存在现阶段对作业过程熟悉的问题。考虑到应用于实际生产的可行性以及提高DLG产品生产作业效率的有效性,文中方法值得在测绘生产中推广应用。

| Abstract: | It presents an integration method of DLG production ,which is based on the free net adjustment . Comparing with the classical method ,this method not only meets accuracy requirements ,but also shortens the work period and improves work efficiency .Lacking experience is the only problem in production . However ,considering its feasibility in practical production and effectiveness in improving work efficeceny in DLG production ,this method is worthy of spreading to the application of survey production . |
