The aim of this paper is to present a program archived for geophysical data processing. The development of the present software package is based on statistical criteria. The GPP package was evaluated by using magnetic, electromagnetic and soil resistance data containing high levels of noise. The efficiency of the GPP package was tested though comparison of the results with similar methodologies followed in a manual procedure using the Surfer tools. The results archived using the GPP software are more than satisfactory, enabling the fast and high quality production of images even during the fieldwork activities.
