In the system of mass (cadastral) valuation of real estate objects the knowledge of territorial dynamics of market prices, territorial distribution of demand and supply is extremely important, because it is used as a basis for economic and mathematical modelling of cadastral value, as well as indicatively - as a price market benchmark of correctness of value determination. The purpose of this study is to carry out geoinformation modelling of a separate type of price surfaces (demand surfaces and supply surfaces), the use of which is possible in the system of state cadastral valuation. Scientific novelty of the research lies in the application of the known method to a new object of research: in the construction of TIN-surfaces of supply and demand when analysing the real estate market in the system of state cadastral valuation. Statistical processing of the initial data was carried out by sampling method using the built-in statistical analysis tools «Descriptive Statistics» MS Excel. Price surfaces were built using MapInfo GIS-modelling tools of MapInfo version Pro 17.0. The TIN model was used to construct the surface. Based on theoretical ideas about the classification of surfaces in GIS, we will consider the supply and demand price surfaces to be pseudo-statistical, since the measurement of this factor was conducted indirectly through the conjugate indicators of the number of offers and the number of references to the advertisement placed on the Internet portals for the sale of real estate. The construction of supply and demand price surfaces allows us to determine the supply and demand ratios for each municipality and for the regional property market as a whole. Supply-demand indicators on the real estate market allow us to draw a conclusion about the market activity, including in certain local territories.
