The relevance of the research. The earth is the most valuable resource, the importance of which is now very difficult to overestimate. Being a means of production, at the same time, it is as a spatial basis for population activity. In today's environment, the issue of ensuring rational and efficient use of land is particularly acute. For this purpose complex analysis and estimation of its economic, climatic, ecological, geological and other characteristics is necessary. One of the types of such assessment is definition of cadastral value of land. In our country it is used mainly for taxation, therefore, it is important to provide accurate and objective results of the assessment. Modern techniques are not perfect, and their use does not always provide the correct and fair value of land. For example, not enough attention is paid for choosing source factors and justification of variant of their accounting at cadastral valuation. Each of these factors may be accounted by some indicators with different dimensions. The article is devoted to the analysis of dependence between chosen indicators and cadastral value on the example of land parcels which are located on the Vasilievsky Island in Saint-Petersburg. The main aim of research is to study the influence of variable accounting of pricing factors on the total cost of urban lands for further specification and improvement of land parcels cadastral valuation methods. Methods. The analysis of objects location was carried out by studying the cartographical sources as well as by visual survey of real estate objects. The values of estimated indicators of land parcels were gathered by the methods of spatial analysis and modeling in geographic information system MapInfo. The land parcels market data were selected by the methods of statistical collecting and data processing with application of MS Office software and SPSS. The authors used the correlation method and regression analysis for statistical models creation and the method of «correlation galaxies» by P.V. Terentev for defining the interdependent estimated indicators at three considered options. Results. When carrying out the cadastral valuation of lands it is necessary to consider the existence of variability of factors accounting by some estimated indicators with different dimensions. Choosing this or that indicator characterizing the influence of a factor should be justified properly. The correlation analysis of indicators revealed different degree of their interdependence that demonstrates that they can be not always interchangeable at creation of statistical models. Structure of the most significant indicators such as the calculated cadastral values depend on the choice of structure of initial estimated indicators of factors.
