Problem in finding a .gpkg file

Hello,
I am new to the sentinel hub and trying to analyse the data of Europe.
I am trying to find out “gadm36_0_EU_EFTA.gpkg” .
Can anyone please help me out in finding the gpkg file or either help me out in making my own.

Thankyou

Hello,

You can find GADM data for each country and for the entire world at the GADM website. You could create a subset for the EU EFTA countries based on the world file. Otherwise, there is NUTS data available on the European statistical office’s portal: Eurostat.
