Ground Penetrating Radar (GPR) is a remote-sensing technique widely applied in archaeology, engineering and environmental sciences. It is a non-invasive geophysical method which uses electromagnetic pulses to create an “image” of the shallow subsurface. In recent years, GPR gained popularity in forestry, thanks to its application in water content estimation, root stress evaluation, root biomass modelling, and roots location. In this paper we present the results of two radar surveys aimed at reconstructing the geometric features of root systems buried at shallow subsurface, thanks to a multiprofile data acquisition and to the use of a three-dimensional software package. Our results show the potentiality of this approach as a reconnaissance method before performing any destructive test.
