The thesis deals with the relevance of Editorial Plan's guidelines for the formation of internal content of mountain maps of the Slovenian Mountain Association. In the first part the concept of mountain maps is explained and is followed by a historical overview of mountain cartography in Slovenia. In the central part of the thesis, first the editorial plan and its importance is presented, then the formation of content is verified with the use of a test section of a map that contains most of the estimated objects with its defined cartographic symbols. Most of the symbols are taken from topographic maps or symbols which have been used for a long time in mountain maps. The thesis focuses on the analysis of a small part of symbols that
have already appeared in some previous mountain maps, but have not been widely recognized, and symbols with entirely new design. In addition to this, also the cartographic
generalization of objects and occurrences is presented.
