Vertical derivative is used in interpretation of potential field anomalies extensively. This filter enhances the details and sharpens anomalies. However difficulty is that by this filter the noises are increased as signals are enhanced. This filter is used with first and second orders normally. However recently vertical derivative is applied with non – integer order, in order to produce a good equilibrium between signal and noise. This method is preferred when anomaly variation throughout the survey area is uniform. In this regard in areas with different types of data compiling a map with different order of vertical derivative is the best methodology. This method is based on calculating standard deviation on a moving window over the study area. In this paper the application of this method on vertical prismatic model and over aeromagnetic data of Abadeh region are discussed.
