怎么会没有人顶？ 同行啊..不会帮顶 点线矛盾对于搞测绘，特别是地形测绘那是很头痛的，这么强大一个功能，建议不要用COMMAND
很多年前弄过一个，虽然不会漏判但会误判，后来地形图弄得少了也就没管它了
应该先检查等高线之间高差是否与基本等高距相符，再考虑点线矛盾
一般用高程点根据比例尺在一定范围内选取等高线，找出离它最近的一根等高线，再找出与它反方向的另一根线或者与这要等高线高差等于基本等高距的等高线来判断，如果有错，从高程点到对应的等高线绘一条直线出来
建议要考虑地物、地貌，比如高程点到最近的等高线间有一个陡坎，这时是不应该计算高程点与等高线高程的差是否小于基本等高距的，另外，你应该说说你的主要思路，而不是直接发一大串代码，毕竟看程序很累，而思路是否清晰，是否可行，这相对比较容易判断
我用了一直卡死，你用的正常吗？谢谢！ 支持一下顶一个 yhly555 发表于 2019-10-15 15:15
