摘要
提出利用DEM数据直接生产大比例尺地形图等高线质量的几个技术问题,通过对问题产生根源的分析,探讨并总结出了解决问题的方法,用于批量生产。
This paper propose several technical problems about the quality of large scale topographic map contours produced derectly by using DEM data. We summarize and probe into a method that solve the problems by analyzing the cause of them, and use it for producting batch contours. It is indicatied in practice that technical method mentioned above is operable and has denifite practicality.
