使用 natural earth 地图
如何用 natural earth 的数据做瑞士地图
开始之前，请装好 GDAL
-
首先把地图包下载下来。在这个下载页面，选择 “Admin 1 - States, Provinces“ 。
为什么呢？我需要内部的省份边界。你可以选择 "Admin 0 - Boundary lines"
-
下载后，请解压缩。
-
使用
og2ogr命令，开始提取瑞士的图ogr2ogr -f GeoJSON -where "ADM0_A3 in ('CHE')" switzerland.geojson ne_10m_admin_1_states_provinces.shp -
让我们打开 geojson.io, 先看看效果吧。
在 echarts 里显示，还需做什么处理
-
natural earth 的数据提供了一些多语言的地名。因为目前， echarts-maps 还仅仅支持 中文，所以需要把名字的属性改一下。

echarts-mapmaker 有一个
property的命令：property -r name_zh,name switzerland.geojson -
再查看的时候，它的名字就是中文的了。
