In the article one introduced the use of the theory of the modelling to the estimation of cadastral values for needs of the qualification of the basis of taxa-tion with the tax from the value real estate. In the research one embraced three precincts of information, situated in the southern part of Wroclaw. The base of the construction of models of the value real estates was determined by the register of prices and values of real estate together with the numeric map. One carried out the essential and statistical analysis of transactional prices contracted in the reg-ister of prices and values real estate. One performed the actualization of prices according to the metameric lineal function of the regress. To the construction of models one applied modified models of the general valuation of real estate worked out within the framework of the project of the sys-tem of the general valuation of the real estates, being a component of the Integra-tive Platform Electronic, realized within the framework of the project "the Crea-tion of the Integrated System Cadastral", performed in the interest of The Principal Office of the Geodesy and the Cartography. Apart from these methods one applied to the qualification of ...
Statistical methods enable obtaining valuable information about real estate market. The information is objective and can be usefull both for individual and mass appraisal. This paper discusses selected issues related to the use of the regression methods in the real estate valuation. They are the metod of trend estimation, the metod of calculation of the price - size relationship for undeveloped land, and the functional form of the distribution function of unit land prices of undeveloped land. The analysis was based on a few thousands of sale transactions in Kraków. This paper also discusses selected issues related to the use of the mul-tiple linear regression in the real estate valuation. They are the functional form of the model, number of the attributes, trend, scale of the values of the attributes and the form of adjustments. Arguments that the dates of sales should be excluded from the list of real estate attributes are brought forward. Also, the paper argues that the regression model should contain an intercept parameter and the scale of the values of the attributes should start from zero.

For many years 3D models representing the terrain surface are used in various fields of science and engineering. The paper shows and describes the pro-cess of data implementation to the DTM, and reviews methods of creating DTM based on the TIN and GRID meshes. The paper presents methods for creating TIN meshes. It also describes the method of height interpolation in raster models based on the measurement data using various algorithms.
