Results evolutionarily – functional approach to the analysis and classification of the existing software by processing of spatial data for support of decision-making at the regional level are provided in operation. The analysis of existing software on processing of spatial data for support of decision-making at the regional level, in which the main objectives and functions, creation time, and also the used types of spatial data were shown, is carried out. The four-stage model of classification of the software which distinctive feature is synthesis of cluster and synergy approaches is developed.
