问题描述
我有一个Geopandas GeoDataFrame，它具有用于绘制气象数据的各种多边形和颜色(我问了另一个问题):
I have a geopandas GeoDataFrame with various polygons and colors that I'm using to plot meteorological data (another question I asked here):

我想将其转换为kml/kmz文件，但是我以前从未使用过该文件类型，因此我不确定如何继续.我尝试使用此脚本，但是它需要一些脚本我没有的高度场.在python中是否有一个好/简单的方法来做到这一点?如果可能的话，我想避免使用在线转换器工具.
I'd like to convert this to a kml / kmz file, but I have never worked with that file type before, so I'm not sure how to proceed. I've tried using this script, but it requires some height field that I do not have. Is there a good / easy way to do this within python? I'd like to avoid using online converter tools, if possible.
推荐答案
所以我可能找到了解决方法...
So I may have found a solution...
我安装了地理空间数据抽象库，并且一直在使用 ogr2ogr 函数.
I installed the Geospatial Data Abstraction Library and have been using the ogr2ogr function.
正如我在问题中解释的那样，我有一个带有多边形和相关颜色的geopandas GeoDataFrame，我将其写入json文件:
As I explained in my question, I have a geopandas GeoDataFrame with polygons and associated colors, which I write to a json file:
with open('/Users/Me/Documents/mydata.json', 'w') as f:
f.write(gdf.to_json())
在终端/命令行中，输入:
In the Terminal / command line, I type:
ogr2ogr -f KML /Users/Me/Documents/mydata.kml /Users/Me/Documents/mydata.json
从技术上讲，您可以使用库"subprocess"从python脚本中调用此命令:
You could technically call this command from within a python script using the library 'subprocess':
import subprocess
subprocess.call("ogr2ogr -f KML /Users/Me/Documents/mydata.kml /Users/Me/Documents/mydata.json",shell=True)
这将生成一个包含基于纬度/经度的多边形的kml文件.但是，它会自动将所有线条颜色设置为没有填充颜色的红色(即使我的json文件中包含颜色).我还没有找到一个好的解决方案，所以我一直在手动编辑KML文件以获得所需的样式.
This generates a kml file with my lat/lon-based polygons. However, it automatically sets all the line colors to red with no fill color (even though my json file has colors in it). I haven't found a good solution to this, so I've been editing the KML file by hand to get the styling I want.
这篇关于将GeoDataFrame多边形转换为kml文件的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
