A prototype system for monitoring landslide and subsidence has been developed within the framework of “Wi-GIM: Wireless sensor network for ground instability monitoring” LIFE+ European project. It is based on a WSN architecture integrating ultra-wide band and continuous wave radar technologies to locate the position of sensor nodes installed on the site. These continuous measurements allow for the realization of 3D displacement maps produced by the deformation of the mesh constituted by the sensor network. In field experimentation is expected to begin in 2016 after the end of the development phase. A prototype system for monitoring landslide and subsidence has been developed within the framework of "Wi-GIM: Wireless sensor network for ground instability monitoring" LIFE+ European project. The working principle of Wi-GIM is to create a mesh of slave nodes whose position is triangulated during time by master nodes, which measure and transmit these data that can then be used to obtain 3D displacement maps. Currently traditional monitoring carried out with total stations is providing movements in the order of cm/year. Such measurements will serve as a tool to verify the performances of Wi-GIM and validate it as an emergency monitoring system. Since the Wi-GIM system will display a precision within the order of magnitude of the cm and an acquisition frequency mainly limited by the energy consumption, the type of phenomena that can be monitored depends on their velocity. The installation of Wi-GIM at Roncovetro and Sallent will be carried out at the beginning of 2016.
