Technological solutions for developing conditional symbols in urban noise mapping using sensors and geoinformation systems

In this article, work has been done to depict the noise distribution on the busy streets of cities on a map based on conventional symbols. When creating the map, the data measured using modern instruments (sensors) and modern geodesy programs (Panorama) were processed, and we can see the limits of the increase in noise impact on buildings and structures on city streets. Noise Impact Noise maps were created on the busy streets of Samarkand based on the Panorama program. The scientific significance of the work carried out is that in the city quarters, coordinates of the location are created using Global Navigation Satellite System (GNSS) devices connected to satellites, that is, instead of points created along the street, noise level meters are installed to measure the noise level, and noise monitoring results are obtained. It differs in that conditional symbols were developed when creating noise maps using GAT (Geodetic Applications Technology) programs and technologies based on decibel data on noise growth along the street quarters, as a result of which methods were developed to describe the noise distribution on busy streets in the city with cartographic symbols.
