HeMOC: a Project to Develop a Multisensor Network for Monitoring Historical Cities

Como is a well-known city located near the homonymous lake in the Northern Italy. Land subsidence has been affected its downtown, with effects on the conservation and safety of historical buildings, requiring the integration of in-situ and urban-scale monitoring of ground deformation. Supported by NextGEN-EU funding, the HeMOC project (“HEritage MOnitor-ing in Como”) is developing a set of seven GNSS permanent stations to be implemented by the end of 2024 in correspondence of Cultural Heritage sites. These stations are based on low-cost GNSS technology developed by GReD S.r.l. company, providing 3D observations for monitoring buildings. GNSS-based observations will be also integrated with in-situ mon-itoring data and used for calibrating ground deformations obtained from Advanced DInSAR (Differential Interferometric Synthetic Aperture Radar) processing of high-resolution data. Results of monitoring sensors will be implemented in a digital platform for data archiving and visualization, which is developed by DkR S.r.l. company. The implementation of the HeMOC project would represent a prototype to be potentially extended elsewhere.
