APPLICATION OF REMOTE SENSING DATA IN THE STUDY OF URBANIZATION PROCESSES

Abstract

Today, as the population continues to grow, the process of urbanization is also rapidly developing. The use of remote sensing data in the study of urbanization processes is considered highly effective and convenient.
In this article, maps of cities in the Tashkent region were created based on classification methods. Considering the relatively coarse spatial resolution of the Landsat satellite, samples were taken from raster data. A flowchart of processes using machine learning techniques in remote sensing data analysis was developed.
The results of the study show that changes in Tashkent indicate an active increase in urbanization. Open lands have significantly decreased, suggesting the construction of new buildings and infrastructure. At the same time, less attention has been paid to the preservation or expansion of green areas, reflecting limited efforts to improve the city’s ecology. Moreover, the expansion of the capital’s territory represents a higher level of urbanization, while the total area of green zones has markedly declined. The proportion of tree-covered areas decreased from 19% to 15% over the past 30 years, which in turn indicates a growing scarcity of greenery in the city.
