The present deliverable concerns the first task of the DIGISOIL’s WP1. Requirements of the proposed system according to the data acquisition and management points of view are first studied. These requirements lead to organise the different components of the system in the frame of a functional analysis where objectives, products and functions are clearly presented. Then, a state of the art on the different geophysical sensing techniques able to contribute to the DIGISOIL’s objectives is performed. Each technique is reviewed in terms of measurement principles, processing and applications, strengths and limitations, and availability of commercial and non-commercial sensors. This part leads to identify the techniques being in the scope of the projects from those considered not suitable enough. Finally, for all of these techniques, a study of possible technical solutions is conducted for identifying the best active source, sensors, measuring strategy and equipment. A synthetic table is finally proposed to roughly identify the composition of the integrated system that will be tested in the next field experiments.
