СОЗДАНИЕ ЦИФРОВОЙ МОДЕЛИ РЕЛЬЕФА ХОЛМИСТОЙ МЕСТНОСТИ ВБЛИЗИ АГМК НА ОСНОВЕ ГНСС ИЗМЕРЕНИЙ

This paper presents a technique for constructing a digital elevation model (DEM) of a hilly area based on the results of GNSS measurements. The traditional methods of measurement using a total station are briefly presented. The main elements of topographic maps for constructing a DEM are given. It is described that the development of digital topographic maps of hard-to-reach areas of the Republic of Uzbekistan plays an important role in the formation of administrative-territorial boundaries and during the period of engineering and survey work. The topographic survey using the Trimble R4 GNSS navigation receiver is described in detail. An analysis of the DEM of the mountainous terrain of the Tashkent region was carried out using geographic information systems. The possibility of using a digital terrain model for structural-geological survey and geophysical research is noted.
