In repo you can find files with GeoJSON encoded data with polygons describing shapes of Poland's voivodeships (pl: wojewΓ³dztwa).
Copy and paste the content into tools like this http://geojson.io/ to check if this is what you were looking for!
polska-wojewodztwa.geojson
contains all Poland's voivodeships together.
The extract_voivodships.py
script extracts each of polska-wojewodztwa.geojson
voivodeships into separate file.
The script requires pip install geojson
