Abstract
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.
Description
One of the most important reasons for limiting the accuracy of measuring horizontal angles using
high-precision angular measurements is not the error of the so-called horizontal air refraction,
which is caused by the external environment.
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.
