To investigate this phenomenon and eliminate its detrimental effects, triangulation and polygonometry, as far as possible, are the first task in science and production to improve the accuracy of the network In this direction, special attention is paid to the use of geodetic measurements in developed countries, including Russia, Ukraine, Germany, the USA and other countries, to take into account the euvironmental impact and improve the accuracy of measurements taking into account the properties of horizontal refraction, which have a significant impact on the measurement results.In the article, the question of the offect of refraction on the results of horizontal angles is specifically excluded. In the hot and dry climate of Uzbekistan, in the polygonomety of river banks, it is possible to increase the accuracy of horizontal angle and line measurements using geographic information systems based on the results offield experiments.en-USElectronic Technologies, High-Resolution Geodetic Measurements, Refraction Effects, Atmospheric Vibrations, Horizontal Refraction, Uneven Light Emission, Modern Geodetic Instruments And Their Capabilities.Article
