ABSTRACT
The use of geospatial visual displays – geovisualization is recognized as a useful way
how to explore, analyze and present geospatial data. Integration of geographical
information systems and virtual reality find its use in various fields from decision
making processes to education. The reconstruction of devastated landscapes and its
visualization through immersive and interactive virtual reality applied for educative
purposes can produce alternative view and new insight in local landscape history and
help to facilitate the extent of the changes. Our objective was to visualize the
fundamental landscape change near Chomutov town (Czech Republic), influenced by
open-pit mining in 1960s. For the purposes of landscape reconstruction, digital terrain
models (DTM) and DTM analysis based on data from Derived State map (1 : 5000,
1953) and Lidar data (2010) were used. Both models were visualized through Virtual
Reality Modeling Language (vrml).

Keywords: Geovisualization, virtual reality, landscape change, Chomutov
