Use GeoDataFrame as a osgeo.ogr DataSource

I have read shapefile into a GeoDataFrame and did some modification to it: 

import geopandas as gpd

# Read shapefile into geodataframe
geodf = gpd.read_file("shapefile.shp")

# Do some "pandas-like" modifications to shapefile
geodf = modify_geodf(geodf)

However, I would also like to apply some functionality of osgeo.ogr module on it:

from osgeo import ogr

# Read shapefile into ogr DataSource
ds=ogr.Open("shapefile.shp")

# Do some "gdal/ogr-like" modifications to shapefile
ds = modify_ds(ds)

QUESTION: Is there any way to use or convert an already in-memory shapefile, currently in a form of a GeoDataFrame, as an osgeo.ogr.DataSource directly?

The way I do it so far is to save GeoDataFrame to file with to_file() and then osgeo.ogr.Open() it again, but this seems kind of redundant to me.

Yes, it is possible. You can pass the GeoDataFrame into ogr.Open in GeoJson format which is supported OGR vector format. Hence, you don't need to save temporary file into a disk:

import geopandas as gpd
from osgeo import ogr

# Read file into GeoDataFrame
data = gpd.read_file("my_shapefile.shp")

# Pass the GeoDataFrame into ogr as GeoJson
shp = ogr.Open(data.to_json())

# Do your stuff with ogr ...

Hopefully this helps!

No. Only formats supported by OGR can be opened with ogr.Open().
