Abstract: In this study, the method of estimating the spatial uniformity of hydrological characteristics and the subsequent zoning of the studied territory by means of GIS applications are described. A new algorithm is proposed for estimating the uniformity of spatially distributed data depending on the differentiation of spatial-correlation functions of the studied characteristics. Mathematical calculation algorithm was implemented using object-oriented C++ programming language. Prospects of researches in the creation of information model of the territory, reflecting the spatial structure, the status and relationships between its separate elements with the purpose of optimization of nature management and making decisions about the management of natural objects are outlined.
