在地质公园中编写Geodataframe文件时出现的“不支持的驱动程序”错误
在地质公园中编写Geodataframe文件时出现的“不支持的驱动程序”错误
提问于 2020-02-13 18:15:54
我正在读取一个GeoJson文件，向它应用一些函数，然后想将GeoDataFrame保存到另一个文件中。
这是我的密码：
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_文件夹’
这是回溯：

driver关键字需要文件格式，如"ESRI“或"GeoJSON”等。
要查看所有受支持的驱动程序，可以运行(确切的输出取决于安装)：
>>> import fiona
>>> fiona.supported_drivers
{'AeronavFAA': 'r',
'ARCGEN': 'r',
'BNA': 'raw',
'DXF': 'raw',
'CSV': 'raw',

默认情况下，KML驱动程序不启用，如本GitHub问题https://github.com/Toblerity/Fiona/issues/97中详细介绍的那样。基本上，KML驱动程序似乎不符合Fiona的质量要求(截至2014年)，不确定它将来是否会被修复。
您可以尝试启用默认禁用的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对于新版本的fiona，您可能需要使用libkml而不是kml。即：
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
