| Popis: | The research is relevant due to the fact that cadastral valuation of land is concerned to be an important part of land plots management. Thus, accuracy and quantity of its results are of great importance for scientific methodological fundamentals of valuation as well as for practice. Being reformed, the system of cadastral valuation of land is not able to provide integration and sharing data from various sources. The aim of the research is to suggest accounting for adverse geotechnical conditions at cadastral valuation of land with the help of geoinformational analysis and 3D cartographic modeling of flooding within the boundaries of urban land. The applied methods: theoretical analysis, methods of research, generalization and other established analytical methods, geoinformational analysis, methods of cartographic data visualization, 3D modeling of geospatial data. Results. On the exemple of Levoberezhye area in Tomsk the authors have carried out the geoinformational analysis on the basis of geotechnical research and spring flood monitoring. The analysis results in outline sketch map of zoning Levoberezhye according to the most favorable hydrological conditions. Specifying the need for the integrated approach to determine the factors of cadastral value, which include the influence of hydrological conditions, resulted in 3D digital modeling of relief and geological constitution of Levoberezhye area. This modeling is able to meet the scientific and practical challenge of accounting for adverse geotechnical conditions of cadastral valuation, keeping the unified state register of immovable property, urban planning and managing territorial entity. Thus the authors proposed the approach to evaluation of negative geotechnical processes and phenomena progressing in urban areas for adjustment of cadastral value. |
