摘要
结合生产实践,介绍了一种通过将最新的卫星遥感正射影像资料与上一轮数字线划图(DLG)数据进行套合的技术路线。利用这种方法能够对1∶10 000基础测绘地形图进行全要素的更新。本文还列举了外业调绘工序容易出现的一系列质量问题,分析了问题出现的原因,阐述了如何在生产过程中加强质量控制措施来提高产品的质量。
This paper combines theories and productive practice,introducing a new technical method to superpose the newest satellite remote sensing material and the last round DLG dates. Using this technique can renew the basis of 1： 1million geographic map. This paper lists a series of quality problems which appear the most easily in the field annotation,analyses the reasons of the problems and expounds how to strengthen the quality control measures in the process of production to improve the quality of product.
