摘要
等高线制图综合是海图生产中工作量比重较大的一项工作,通常采用人工处理的方式,效率较低,影响成图速度。根据海图等高线制图综合特点,利用ArcInfo系统相关功能,研究提出了一套相对较好的等高线自动制图综合方法,并在实际作图过程中得到了较好的应用,提高了海图生产效率。
The workload of contour cartographic generalization in chart production is very big.Usually,this work is disposed inefficiently in manual way,which slows down the producting speed.According to the characteristic of chart contour cartographic generalization,this paper proposed a good method to solve this problem by using the related function of ArcInfo,which has been used in the practical chart production,and enhanced the efficiency.
