ABSTRACT
Classification plays a significant role in the simplification of data visualisation. Instead of individual values, which number can be thousands, there can be obtained only few classes with known range and number of values in it. That results in clear and easy-interepretable thematic map. Hence the quality of data classification carried out automatically in GIS software packages is of great importance. The purpose of the paper is to compare the tools that the researched programs deliever in order to carry out data classification as well as analysis of quality of data classification performed.
Key words: data classification, methods of classification, GVF.
