摘　　要：目前使用的数字化成图软件在展绘高程点时,高程注记点存在较多压盖图上已有实体的情况,使得自动展绘后仍需要通过手工编辑进行合理处理,导致工作效率不高,耗时较多。本文在总结了一些以往作者解决该问题的方法的基础上,对其欠考虑的地方做了算法上的改进,并使高程注记以属性块的形式插入到图中,增加过滤高程点功能,同时给出VBA语言实现该算法的部分程序。实验证明,利用本改进方法展高程点,工作效率得到极大的提高,高程注记的位置和顺序更加合理,图面显得清晰美观。At present, when the digital mapping software is used to plot elevation points, it has the problem that elevation notations frequently cover the entity existed, which will lead to many manual editing processing and waste a lot of time. In view of this situation, this paper improves the unreasonable algorithms used by others before, makes the insert of elevation notations as an attribute block, and adds the function of elevation point filter. In this paper, parts of the programs to realize this algorithm by VBA are given. It is concluded that this improved method can improve work efficiency and make the location of the elevation point become more reasonable and the map become more clear and beauty.
