The zoning of urban areas is the basis of the taxation system. The constant development of cities leads to changes in the factors reflecting the conditions of exploitation of territories. This causes the need to promptly change the existing zoning scheme. Reasonable and prompt changes are possible only on the basis of geographic information systems. During zoning, influencing factors are converted into graphical objects of GIS-project layers. In the GIS-project layers-factors are superimposed on each other, taking into account the sign of influence. As a result, zones are obtained that have similar total coefficients. If the boundaries of the obtained zones do not coincide with the boundaries of the existing zones, it is recommended to change the existing boundaries taking into account the new conditions. The proposed technology is tested on the example of zoning the territory of Frunzensky district of St. Petersburg. The above approach makes it possible to promptly adjust not only the zoning scheme, but also to reasonably change the taxation rates, which will lead to an increase in the efficiency of the use of the city territory.
