Approaches to geoinformation modelling of urban territory to integrate the environmental component into the system of state real property cadastre

Abstract

The relevance of the discussed issue is caused by the necessity to enhance the objectivity and reliability of information on land plots in relation with the conducting reform of the system of State real property cadastre. The integration of an environmental component into the system of State real property cadastre is relevant to the maintenance of high-polluted urban territories. Nowadays there are no approved standards in this field, and various techniques proposed by experts are based on analysis and assessment of existing contamination levels of environment components. The urban environment is not considered as a dynamic system, and its development over time and space is not taken into account. Thus, the complex analysis of time and space dynamics of pollutants in accordance with natural conditions and city infrastructure is essential for the system analysis of urban environment. The aim of the study was to determine an approach to integrate environmental component into the system of State real property cadastre by geoinformation analysis and 3D cartographic modeling of time and space dynamics of pollutants in urban environment. The methods: geoinformation analysis, cartographic modeling, cartographic visualization techniques, 3D cartographic modeling. The results. The authors have proposed the approach to assess urban environment taking into account the patterns of pollution dissemination and proved the logical sequence of integration of heterogeneous environmental data for modeling pollution distribution. The digital relief model and digital terrain model of Novosibirsk city were formed. The environmental database of Novosibirsk city was developed. The authors carried out the zoning of city territory by composite index regarding environmental risk and designed a 3D model of pollution dissemination. Conclusion. The approach introduced provides the dynamic analysis of urban environment as a result of interaction of natural and anthropogenic processes determining pollution dissemination. This provides the detailed and objective assessment of environment of cadastral quarters and lays the foundation for integration of the environmental component into the system of State real propert y cadastre.
