Presented here are the means of generating and possibilities for applying a digital map of sequences of forest/non-forest states in a study area, as based on topographic maps for 7 instances in time (between 1800 and the present day). There is also
a brief description of cartographic material used, as well as the methods applied in generating a variability model. The study area was then analysed from the point of view of differences in the aforementioned sequences of forest/non-forest states
