Ecotones are significant part of almost every landscape structures and have a significant effect on the distribution of species. Spatial variability of ecotones has resulted in problematic modelling, analysis and visualization of these landscape forms. Their spatial variability and fuzzy character are causing uncertain and problematic handling in GIScience. Uncertainty of ecotones in the landscape arises from many sources, including complexities inherent in ecosystems and their disturbance processes. However, gaining knowledge about ecosystems at the landscape level is often impeded by limitations in collecting comprehensive, representative, as well as accurate data sets. The investigation into ecotones enables a better understanding of the causal relationships between certain landscape elements and landscape utilization categories. Visualization of spatial uncertainty is still challenging topic for cartographic community with many unsolved research questions. The presentation explores the possible visualization methods for portrayal ecotones based on detection, description and analysis of geographic boundaries of Trkmanka river catchment with respect to cartographical rules and cognitive aspects.
