摘要
Systems and methods for calculating gravity and gravity gradient terrain effects. The method includes a step (1700) of receiving a digital relief model (DRM) and gravity and/or gravity gradient data recorded at observation stations; a step (1702) of calculating with a computing device gravity and/or gravity gradient terrain effects at observation stations based on (i) a triangulated surface of the DRM and (ii) an adaptive triangulation method; a step (1704) of removing the gravity and/or gravity gradient terrain effects from the gravity and/or gravity gradient data to obtain gravity and/or gravity gradient terrain corrected data; and a step (1706) of generating gravity and/or gravity gradient anomalies of a surveyed subsurface based on the gravity and/or gravity gradient terrain corrected data.
