Description: The resolution of regional and residual components arising out of the deeper and shallower sources from the observed Bouguer gravity anomalies is an ageold problem. Several analytical techniques have been developed to compute the regional or residual. The common shortcoming of these methods is that the total data set is considered to evaluate the regional. As a result of this, a small portion of residual is left out in the regional. In our new technique, the entire data set is no more required for regional computation. Instead, a square or a rectangle region is chosen and the gravity values at its corner and mid-side nodes represent the regional. The weighted sum of these discrete gravity values yields the regional field. This technique has been tested for gravity data sets in several fields and the performance in each case has been better than that obtained by the existing techniques.
