两张图都画省界比对过,中国范围内基本都是匹配的

这个有什么用?原底图中信息太多,基本上搞科研都没人会需要用到这种底图。另外,我印象中 @liuzhumei 说过,即便是用了原始底图也需要重新审图,因为原始底图也是可以被修改的,所以并没有解决问题。

我是根据这个视频,以及这个视频下面的评论得到的信息:

根据这个up主和下面评论的人所说情况综合信息来看,他们那种大改后的图也能用原图的审图号,我们这种单纯叠图不算什么,发国内期刊不用再送审

我感觉这篇文章的内容跟GMT并没有什么关系。

目的是为了解决让 GMT 绘制的插图有审图号这个问题。解决方法的核心就是使用近似投影参数让 GMT 绘制出的投影能叠加匹配有审图号的标准地图。

如果不用这种方法,就只能用arcGIS进行叠加匹配。多学一个gis软件对于很多用户来说就没必要。

属于特定国情下的绘图技巧,有相当一部分受众,我建议至少保留一个链接,可以给有需要的用户查阅。
