python-2.7 - 将 GeoDataFrame 多边形转换为 kml 文件

Question

我有一个带有各种多边形和颜色的 geopandas GeoDataFrame，我用它来绘制气象数据(我问的另一个问题 here):

17  #1a2b7d POLYGON ((-97.1721233852856 32.59996829071199,...

我想将其转换为 kml/kmz 文件，但我以前从未使用过该文件类型，所以我不确定如何继续。我试过使用 this脚本，但它需要一些我没有的高度字段。在 python 中是否有一个好的/简单的方法来做到这一点？如果可能，我想避免使用在线转换器工具。

fiona由 geopandas 包裹的库支持非官方的 KML 驱动程序，您必须手动启用。

import geopandas as gpd
import fiona

fiona.supported_drivers['KML'] = 'rw'

gdf = gpd.read_file(gpd.datasets.get_path('naturalearth_lowres'))
gdf.to_file('test.kml', driver='KML')

请注意，它也可以读取 KML 文件，但在“嵌套”kml 文件上效果不佳，请参阅此 gist更多细节
