Abstract
ABSTRACTThis study presents an analysis and visual representation of landscape diversity in the Czech Republic. The Czech Republic is administratively subdivided into regions, which are further subdivided into districts; the basic territorial units used for the calculation of diversity were the districts. Landscape diversity was calculated from the freely available CORINE Land Cover (CLC) data for the Czech Republic. Additional data (the district and region layers) were taken from the digital vector geographic database of the Czech Republic ArcČR® 500. The Main Map (scale 1:600,000) shows landscape diversity calculated on the basis of Shannon entropy. For the purposes of visual representation, the effective number of categories in each district were calculated; the map also shows the prevailing type of land cover in each district. For comparison, an accompanying map shows landscape diversity at the regional level. Other accompanying maps contain information on CLC data, which is closely connected with landscape diversity. The four accompanying maps are at a scale of 1:1,800,000. Further information is also presented in addition to the maps (representation of CLC categories in the Czech Republic, brief texts characterizing the basic methodology used: CLC and the calculation of landscape diversity).

Summary
The landscape is a complex system of mutually interrelated and interdependent elements and components, which are both natural and anthropogenic in nature. Landscapes may be described and evaluated from various perspectives. Precise analyses of the structure and development of landscapes frequently use quantitative indicators enabling researchers to measure, quantify and evaluate certain characteristics of landscape structure. Quantitative characteristics of landscapes are determined by means of landscape metrics, which express the structure and development of a landscape. An advantage of quantitative indicators is that they enable researchers to obtain exact numerical data on landscape structure. Numerous landscape metrics are used – for example, McGarigal and Marks (1995) list 100 landscape metrics, though many of them are mutually interdependent (Cushman, McGarigal, & Neel, 2008)
