ОБ ЭЛЕМЕНТАХ ТОПОГРАФО - ГЕОДЕЗИЧЕСКОГО ОБЕСПЕЧЕНИЯ ОКРЕСТНОСТИ ОЗЕРА ИССЫК-КУЛЬ В 1990-2025

This paper presents classical and modern data on topographic and geodetic support for the Issyk-Kul Lake region. It briefly describes the physical and geographical characteristics and factors influencing tectonic changes in the surface of the study region. The coordinate systems used for topographic surveying of the coastal zone are described. The trapezoid gridding by nomenclature and the scales of topographic maps for this region for use in geographic information systems are described in detail. Classic geodetic points, modern GPS points, and GNSS stations located around Lake Issyk-Kul are presented numerically and graphically. Geodetic coordinates of the 8 SGN points were calculated relative to the rectangular Gauss-Kruger coordinates. The results of navigation measurements in the district center of Bosteri are presented in this article.
