This study is based on the use of geophysical investigations, in the case of a gravity method, in order to identify underground cavities. In this study, we applied calculation of downward continuation on a plane located underground and close to anomaly. This gravity value could indicate the superior specifications of the anomaly in comparison with estimated results of the calculated gravity data on the ground. By calculating the downward continuation of the gravity data, features such as shape, size and depth of the anomaly would be determined. This method is used for delineating subsurface cavities for instance, to avoid hazards of construction activity in the vicinity of these areas. In this paper, the method is run using MATLAB programming and eventually capability of this method and developed software are shown by applying on both synthetic and real gravity data.
