The expediency of creating a universal service center (USC) in a specific agricultural region has been revealed hereby. Its tasks have been substantiated as an executive of technical services. Basing on the formulated tasks, the structure of the operation of the USC has been developed within the framework of the system “Plant – service executive – consumer of the service”. The methods for determining the rational location of the USC in the territory of a particular region have been developed and implemented. An example of calculation of the functioning parameters of a universal service center has been presented. It was revealed that the economic effect of the USC would be achieved by reducing the route of mobile service workshops in the process of providing services to cars.

“…In this manuscript, we present a case study from Uzbekistan that examines up-to-the-date practices of geodetic measurements for build-up area expansion. Uzbekistan is a rapidly urbanizing country in Central Asia [5], and the expansion of its built-up areas is a significant concern for policymakers and researchers alike [6,7]. The case study focuses on a specific urban area in Uzbekistan, providing a detailed analysis of the geodetic measurement techniques and instruments used to assess and monitor the expansion of the built environment [8,9].…”

Up-to-the-date practices of geodetic measurements for build-up area expansion: a case study from Uzbekistan

This paper seeks to contribute to continuing efforts to better understand and control the effects of urbanization on our environment and society by offering a thorough review of the most recent geodetic measuring techniques for build-up area growth. In this article, we give a case study from Uzbekistan that looks at current geodetic measuring techniques for expanding build-up areas. Uzbekistan is a fast urbanizing nation in Central Asia, and politicians and experts are both deeply concerned about the growth of the country's built-up regions. The case study, which offers a thorough investigation of the geodetic measuring methods and tools used to gauge and track the growth of the built environment, is focused on a particular metropolitan region in Uzbekistan. Therefore, this article gives a summary of current geodetic measurement methods, including remote sensing methods like LiDAR and satellite imaging as well as surveying methods like total station and GNSS. The case study also emphasizes some of the difficulties and restrictions related to these methods, such as the requirement for precise geodetic control points and the inadequacies of satellite imaging in regions with thick vegetation or cloud cover.
