Thanks for your response. I would recommend to compare the latest aerial imagery with the archive version - see the last link in the "ČÚZK Ortofotomapa" paragraph at https://wiki.openstreetmap.org/wiki/Cs:%C4%8Cesko/freemap - this way you will have a better picture which of the ways are likely permanent. Strava Heatmap may also help in some cases. I often switch among more than 10 different background layers when mapping forest and field tracks. Please note that the ČÚZK aerial imagery is actually not "satellite". It is photographed from an airplane.
