Abstract

Geographic information technology has now established itself in various fields of application. The advantages of their use, especially in the cadastral valuation, on the outcome of which the relationship between the taxpayer ̶ the owner of the property and the tax receiver – the municipality depends, are undeniable. However, the role and importance of automating the processes of analysis and questions of the implementation of the stages of cadastral valuation in the entire system of cadastral valuation and taxation of real estate are not fully disclosed in the scientific literature. For many types of spatial operations used at different stages of the cadastral valuation, the end result is the presentation of data in the form of thematic maps and plans, supplemented, if necessary, by reporting documents, three-dimensional images, graphs, charts and tables, photographs and other means. In this regard, the possibilities of using GIS during cadastral valuation were considered, among which were calculations of the values of pricing factors, estimated zoning of the territory, and others. The analysis of reports and draft reports on the results of the state cadastral valuation of land plots and capital construction objects in the land of settlements was carried out. The main directions of the use of GIS in the regions in the framework of determining the cadastral value of valuation objects are identified. At the initial stage of the cadastral assessment should be used GIS. GIS is a multifunctional information system designed to collect, store, analyze and graphically visualize spatial data and related information about the necessary objects, which allows you to combine, organize and display on the map relevant and reliable data from various information systems. The most used are MapInfo and QGIS. The most important GIS functionalities in the field of assessment are identification of objects of assessment, determination and calculation of pricing factors, estimated zoning of the territory, georeferencing of objects of cadastral assessment, transformation of coordinate systems. The article substantiates the possibility of using GIS in carrying out cadastral valuation, including the calculation of the values of pricing factors, estimated zoning of the territory, and others. The regions using digital thematic maps for real estate assessment, as well as regions using the functionality of geographic information systems were identified.
