To find the proper symbology for a map one has to analyse the cartographic data. The core of this process of analysis is to access the characteristics of the data to find out how they can be visualized, so that the map user will interpret them properly. The first step in the analysis process is to find a common denominator for all the data. This common denominator will then be used as the title of the map. For instance, if all data are related to land use collected in 2005, the title could be “Land use of . . . 2005”. Second, the individual component(s), such as land use, and probably relief, should be analysed and their nature described. Later, these components should be visible in the map legend.
