Abstract

This projects deals with modelling of land cover change in abandoned landscape. The study site is located in the military area Hradiště, around the former village Tocov.

Due to lack of historical vegetation data on landscape scale, historical aerial photographs were used as a primary source of data, which were orthorectified, mosaicked and automatically object oriented then classified in two categories woodland and grassland. Changes between two successive classified images were modelled with generalized linear models with mixed effects (lmer).

Variables that were derived from digital elevation model, former land use and spatial variables computed with algorithms based on cellular automata were used. In order to verify the model predictions with the actual situation and for easier interpretation and visualization of results, a new application PEMZOK (Spatially explicit model of overgrowth of abandoned landscape) was developed.
