啥都要自己上手

前言

这是很早之前的工作了，重新整理了一下，大概是2019年的时候，当时各大App加大了对中国地图完整性规范性的审核，而我们App中有内嵌中国地图相关的内容，但是当时使用的JS的jVectorMap展示的地图，官网的地图由于地图数据不完整，缺少对应得关键位置数据，导致App被下架。差评啊，到现在他们都没加。

本来这不属于我的工作，毕竟当时的我主要搞Android，这是另外一个小组的任务，可是按照任务排期，他们得把这任务排好久，我们又着急App上线，只好跟领导们申请，临时把任务让给我们做，做完后再做个汇报和交接。

没办法，自己动手搞吧！

jVectorMap

先得了解jVectorMap啊，官网先see一波。
jVectorMap官网 ( https://jvectormap.com/ )

Maps

大概了解到这是基于 SVG（Scalable Vector Graphics） 的一种可缩放矢量图形。
官网提供的Maps ( https://jvectormap.com/maps/world/asia/ )
在这些数据里可以发现，地图数据中缺少祖国地图中很关键得数据。

做好的地图下载

不想看的可以直接下地图包，目前就做了世界地图和中国地图。需要做别的，可以继续往后看。

世界地图修订

});

既然它没有，那我们就自己加！既然是矢量图，那简单啊，先搞世界地图和亚洲地图，只要我们把台湾的矢量数据 Copy 到中国里就搞定了。

矢量图编辑工具 SVG-Edit

然后就剩下九段线了。这个不是很好弄。因为没有现成的数据，要自己去画矢量图。
工具：https://svg-edit.github.io/svgedit/
编辑页：https://6098683962bf91702907ee33--svgedit.netlify.app/editor/svg-editor.html
注意：随着版本发布，编辑页链接可能存在失效问题，直接从主页找对应版本的编辑页即可。

这里我们可以把已有的地图数据导入，然后再从百度地图上截图一个九段线地图参考。直接用画笔参照地图描绘即可。

SVG Edit.jpg

因为有点偏转角的问题，所以整体上没法严丝合缝，但是大概轮廓对的上就行。按照九段线描述即可。由于百度上实际海上国境线花了10条，所以我也画了10段。

SVG Edit2.jpg

然后将所有的数据导出即可。

由于画的不好看，存在随时调整的可能，而且九段线不属于实际区域，属于一个辅助线的存在，所以单独抽出来，以方便后续优化和修改。

完成后的地图效果图如下：

svgmap.png

效果看着还可以。当然，如果小伙伴觉得难看可以自己稍微修订下。哈。

一起画台湾

按照同样的方式。我们可以在中国地图中也添加入九段线和台湾省。
上面的方式说的比较笼统，那么借着画台湾，我们可以简单的了解下 SVG Edit 的使用方式。

导入图片和地图不说了，大家稍微看一下就都能了解。
这里说一下怎么会调整手抖画的七拐八拐的矢量图引入正轨。
注：截图为较早的版本，有时间了我更新下新版本的操作界面。主要是新版本用的不太习惯。还在尝试。

使用画笔先简单画个雏形。

demo.jpg

选中之后，选择显示标记点（新版本是双击线条也可以看到）

demoTW.jpg

然后可以拖动关键点进行线条的微调整。

demoTW_Point.jpg

也可以断开两个点

delete point.jpg

最后出图，实际的展示效果。
