Automated geomatic system for monitoring historical buildings during tunneling in Roma, Italy

The present work is focused on the preliminary results obtained through the geomatic integrated monitoring system currently running at the test site of the Basilica of Maxentius in the Roman Forum. The system is aimed at controlling a number of archaeological sites which can be potentially affected by the tunneling works for a new metro line which is presently under construction. It includes different high precision geomatic sensors controlled by a centralized control station which continuously acquire data at high frequency. In order to identify a reliable processing procedure and assess the quality of the collected data, we started to develop and experiment a preliminary analysis of the data collected in the first period of the system operation (before the start of the excavation works). This activity allowed us to assess the performance of each sensor, focusing on the capability of the system to control also the stability of the monitoring stations. The obtained results will be adopted to better define an automated procedure for future massive data processing.
