Abstract: The Capacitor Gravimeter (CG) and Capacitor Gravimeter Program (CGP) are used for recording and processing data in the survey field works. The CG calibration with reference points at Pathum Thani Province (National Institute of Metrology); gBASE = 9.78312 m/s2 and gCG = 9.97879 m/s2 (approximation error 2{6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465}). Ramkhamhaeng University, Prachinburi Campus is studying of land subsidence, based on the gravity anomaly focus on Simple Bouguer Anomaly (SBA) divided into three transects of the study area. The results of calculating SBA data are shown maximum and minimum value of transect (3) and transect (2), respectively. The SBA-transect (2) value may lead to a lower density than the surrounding areas and caused the land subsidence (DMR, 2011).
