This article describes creation of a gravimetric map for the Turkistan Region in Kazakhstan, to be later on used in solving geological, geophysical and geodetic problems. The gravimetric surveying data on the Turkistan area are to the courtesy of the National Geological Service (NGS JSC). The archival gravimetric maps were scanned, digitized, geographically fixed and systematized. The diagrammatic maps of the area coverage are given with the specified scales and density of surveying. The comparative analysis of the precision of the global geopotential model XGM2019e_2159 is carried out using the land-based and air-borne gravity data on the test area. The map of the Bouguer anomalies is created for the Turkistan Region at a scale of 1:200000, and the gravity field transforms are made using the radially averaged strength spectrum, to determine the regional and residual gravity anomalies and for the further geological characteristic of the Turkistan Region.
This research is funded by the Committee of Science of the Ministry of Science and Higher Education of the Republic of Kazakhstan (Grant No. BR21882366 «Development of a geoID model of the Republic of Kazakhstan as the basis of a unified state coordinate system and heights»).
