将 Geodataframe 写入 geopandas 中的文件时出现“不支持的驱动程序”错误

Question

我正在读取 GeoJson 文件，对其应用一些函数，然后想要将 GeoDataFrame 保存到另一个文件。

这是我的代码：

import geopandas as gpd
df=gpd.read_file('C:/in_folder/data.json')
df.to_file(driver='C:/out_folder', filename='df.json')

但这会产生以下错误：

DriverError：不支持的驱动程序：'C:/out_folder'

这是回溯：

    130             elif self.mode not in supported_drivers[driver]:

DriverError: unsupported driver: 'C:/out_folder'

有谁知道发生了什么事吗？

默认情况下不启用 KML 驱动程序，如本 GitHub 问题https://github.com/Toblerity/Fiona/issues/97中所述。基本上，KML 驱动程序似乎不符合 Fiona 的质量要求（截至 2014 年），不确定将来是否会修复。

您可以尝试启用默认情况下禁用的 KML 驱动程序。

import geopandas as gpd, fiona
fiona.drvsupport.supported_drivers['kml'] = 'rw' # enable KML support which is disabled by default
fiona.drvsupport.supported_drivers['KML'] = 'rw' # enable KML support which is disabled by default

对于较新版本的 fiona，您可能需要使用 libkml 而不是 kml。IE：

fiona.drvsupport.supported_drivers['libkml'] = 'rw' # enable KML support which is disabled by default
fiona.drvsupport.supported_drivers['LIBKML'] = 'rw' # enable KML support which is disabled 
gpd.read_file("/path/to/your/test.kml")
