I am getting an empty bbox list when I try to split my data into boxes.
Please check that your country shape geometry has coordinate order longitude-latitude. If that is the case, could you share the geometry with us?
My notebook is similar to the land use land cover classification of Slovenia.
If you are using
eo-learn repository then the reason for your problems is that the geometry of Slovenian border is given in UTM 33N coordinate reference system and not in WGS 84.
sentinelhub.CRS.UTM_33N in your code should solve the problem.
I got it thanks @maleksandrov !
