摘要
A gravity survey is conducted by obtaining relative gravity measurementsfrom a plurality of survey points using a relative gravimeter, obtainingabsolutegravity measurements from a subset of a lesser plurality of the survey pointsdesignated as combination survey points, determining a correction factorrelatedto any difference between the relative and absolute gravity measurements ateach of the combination survey points, and correcting the relative gravitymeasurements made at the survey points which are not combination surveypoints using the correction factor. The absolute and corrected relativegravitymeasurements at the survey points constitute the gravity survey.
