| The old city centres of all major cities increasingly demand the underground of the infrastructure in order to cope with the transportation needs. These areas represent a great challenge from a constructive point of view since the foundations of the buildings consist of an aggregation of previous constructions over the same place. This endorses thorough monitoring activities during any underground construction. The capabilities of the persistent scatterer interferometry (PSI) can be exploited in order to cope with this monitoring needs. However, the old city centres represent the most challenging urban scenario since the rooftops are usually filled with air conditioning systems and due to the fact that the streets are usually crowded. This work assess the applicability of the PSI technique under this challenging scenario. It proposes a set of classification indexes in order to make the most of the capabilities of the PSI algorithms. These indexes allow an objective assessment of the results, as well as remove the high dependency of the results on the sensor and algorithm used in the processing. The applicability of the technique and the proposed indexes is validated in the old city centre of Madrid comparing the results against on ground measurements. The most demanding urban environment to be analysed by the PSI remarks the potential and limits of the technique. | |
