在项目中往往需要用echarts或者其他可视化工具来生成地图，但是echarts关闭了下载数据窗口，在此分享一个在线生成地图geojson数据的地址。
如下:
http://datav.aliyun.com/tools/atlas/#&lat=33.521903996156105&lng=104.29849999999999&zoom=3

在这里插入图片描述
上述的网站只能精确到区县级json数据，而乡镇级json一般需要第三方购买。
此时我们可以在 http://geojson.io 网站上手动绘制乡镇地图。

右侧红框中的数据采用的是上述中第一个地址获取的区县数据。
进入http://geojson.io后我们便可以使用网站自带的一些功能添加线条和区域了。添加的会自动编译成geojson格式。
