Reading and Writing Feature Class in a File Geodatabase Using Geopandas

Question

I am able to read and write shapefiles in ArcGIS Pro using geopandas, but it would be more useful to read and write within a geodatabase.  When I try to read a feature class in a file geodatabase, I get the following driver error:

DriverIOError: Attempt to create csv layer (file) against a non-directory datasource.

When I try to write a geodataframe as a feature class, I get the following error:

No such file or directory

I am wondering what I'm doing wrong... Please see my script below:

file = outGDB + '\FC_Name'

FC_gdf = gp.read_file(file, driver = 'FileGDB'))

FC_gdf = gp.to_file(file, driver = 'FileGDB')

Thanks for your help!

I think this is an issue with having the FileGeodatabase drivers in a place that gdal / fiona can find it. Those two libraries are the backend for GeoPandas. You can get this setup, but it can be a pain to get it all working. For example: https://gis.stackexchange.com/questions/378890/adding-support-to-esris-filegdb-driver-when-fiona-gdal-osgeo-were-installed-thr

An alternative is to use the ArcGIS API for python and read and write a spatially enabled DataFrame. GeoPandas is better in a lot of ways, but SEDF generally works well with File Geodatabases and an ArcGIS Pro license: https://developers.arcgis.com/python/guide/part2-data-io-reading-data/
