Relief of Czechia: quantitative evaluation in the GIS environment
The authors used a new GIS-based geomorphological map of Czechia in the scale of 1:500,000 (Demek, Balatka, Kirchner, Mackovčin, Pánek, Slavík 2009) for computer aided quantitative evaluation of the relief of the country. The analysis showed that erosion landforms prevail in Czechia (77.14% of the Czech territory). Summit and piedmont planation surfaces (etchplain, rock pediments, and cryopediments) that take 8.87% of the Czech territory were quantitatively evaluated over the whole Czech territory for the first time. The most common accumulation landforms were loess surfaces (8.04%) and fluvial landforms like floodplains and accumulation river terraces (8.20% of state territory). Polygon layer of the new GIS-based map enabled the evaluation of the geomorphodiversity of the Czech territory.
