In this work, a new informatics program in ‘C++’ language for the separation of the regional and the residual anomaly is presented. The proposed approach lies on the limits observed in the former code of the potential data processing by the least square method (POLYFIT in FORTRAN 77(Radhakrisna et al. 1990), GMSEP. PAS in PASCAL (Njandjock et al. 2003). In order to make, it has established an algorithm thanks to a mathematical analysis that takes into account all parameters that the least square method implies. The validation of this program has been enabled by the comparison of its results with those of the former codes. The improvements on the treatment of a very big number of data and a separation at a high degree have been put in evidence by the gravimetric data processing of the zone of Yagoua at north Cameroon and with the same opportunity, it has been observed that these improvements permit a more pushed analysis of the structure with the determination of the features; more deep, least deep and those that spread of depths to surface.
