Sunkio anomalijų ir pagreičio redukavimas

Abstract

Algorithms of free air gravity anomalies, Bouguer anomalies and gravity value reduction anomalies are presented in the article. Algorithms suitable for coordinate system LKS 94 presently used in the Lithuania, gravity system and normal field GRS 80. Data taken from the gravity map or from gravity observations could be reduced using these algorithms. Gravity observations could be performed on the Earth's surface or on the water or under the Earth or water. The given formulas could be used in research of Lithuanian gravity field, for geoid and normal heights determination, for establishing geodetic vertical and gravimetric networks.
