Gravity preparation for the geoid of the Lithuanian territory

Abstract

Gravity data of the gravity network stations, survey of scale 1:200 000, survey of the Baltic Sea and Kuršių lagoon was prepared lor the Geoid determination. Gravity data was reduced to the system of IGSN 71. Normal Gravity Field GRS 80 was used. Density of 2.67 g/cm3 for the calculation of the Bouger anomalies was used. Data presented in the ETRS 89 Geodetic Coordinate System, ellipsoid - GRS 80, cartographic projection - UTM.
