The master's thesis deals with the classification of land use. It provides a theoretical background for classification systems and presents ten examples of actual land use classifications in selected countries and pieces of research. The examples involve countries with an established approach to registering land use, countries that have modernised it in the past ten years or are doing so at the moment, transnational registering projects, directives and other projects aiming to manage land use registering. The proposed classification of actual land use was developed on the basis of examples and recommendations for classification systems in line with the European INSPIRE Directive and implementing or ongoing projects, such as EAGLE (2013) and LBCS (2000). Each category of land use was described and linked to the Classification of facilities. The discussion searched for a connection between the proposed classification of land use with the categories of land use allocation under the Spatial Planning Act (2007) and the Standard Classification of Activities. Moreover, it examined whether the proposed classification of categories can serve as the basis for identifying builtup and greenfield land. The research results suggest that a register of land use is necessary, but insufficient for further analyses.
