Modern technologies of geospatial analysis during urban territory planning

Abstract

Zoning is an important factor of territorial organization and management of the economy of a separate territorial unit – country, oblast, district oblast, city, district city, selective districts, zones of communal and administrative division, and others. Zoning involves the distribution of the territory taking into account the objective laws of the territorial division of labor, the formation of territorial-production complexes of various scales, etc. The article analyzes the main ideas of specialists regarding the issues of zoning the city territory using GIS technologies and methods of geoinformation analysis using the example of the city of Odesa. The purpose of this work is to develop an information model of a multifunctional geo-information system for solving territorial planning problems of the city of Odesa using geospatial analysis methods. Investigate the possibilities of using geospatial analysis methods to ensure the implementation of mapping of various scales and thematic direction on the example of the city of Odesa. Method. The methodology of performing zoning works using geospatial analysis methods mainly corresponds to the following algorithm: 1- processing of analytical data received in electronic form, with the aim of bringing it into the data input format of the ArcGIS software; 2- execution of the geocoding operation based on the address part of the analytical data; 3-allocation of elementary fragments of the city territory that meets the requirements for district boundaries; 4- construction of a population density model; 5-determining the population of elementary fragments; 6- determination of the boundaries of the historical part of the city (“Porto Franco”) according to the maps of the 19th century; 7-binding and defining the boundaries of the historical part of the city according to the digital map; 8- determination of the population currently living in the historical part of the city; 9-determination of potential district boundaries; 10-determination of zoning options; 11-registration of documentation for each variant of zoning; 12-analysis of the results, if necessary, change of criteria for the zoning procedure and repetition of the procedure for designing the boundaries of the districts. Scientific novelty and practical significance – for the first time, the development and research of an information model of a multifunctional geoinformation system for solving the problems of territorial planning of the city using geospatial analysis methods over a long period of time has been carried out.
