Abstrakt: Illegal activities in the landscape (e.g. illegal waste dumping) may pose significant environmental and social risks in different areas, such as human health, economy, aesthetics, etc. Their identification and spatial localization are a basic prerequisite for solving potential problems; therefore, it is important to look for methodological procedures for monitoring these phenomena, including their cartographic visualizations. The number of satellite-based remotely sensed datasets available for land cover (LC) change identification has increased markedly since the launch of the first Landsat satellite in 1972. Many change detection techniques have been developed and applied during this period to assess LC changes. Several books and review papers have summarized and compared the various detection techniques (Giri 2012, Goga et al. 2019). In general, human impact on landscape causes categorical changes in its use: change of one type of landscape to another, e. g. arable land to built-up area. As such changes may influence the condition of the landscape, it is important to determine where and to what extent they take place. Legal changes in landscape involve planning and recording in the Land Register, agricultural, forestry or water economic plans. However, the landscape is ever more frequently attacked by illegal human interventions, and their tracking may be difficult because of remoteness, difficult access, etc. Nowadays, various methods of LC change identification are applied. The most progressive ones combine remotely sensed data (optical and radar) with data from environmental databases, thematic maps and field survey. This approach is also suitable for the identification of LC changes caused by illegal human activities. The solutions offered by this paper are based on the application of the above-quoted approach. They will document the possibilities of identifying three types of illegal human activities in the landscape: (i) illegal dumps (near roads and urban structures); (ii) illegally ploughed protected meadows (especially in cases of contact of protected meadows with agricultural land); (iii) illegal clear-cuts of non-forest tree vegetation in the agricultural landscape.
