“…High density of registered points, accuracy and noninvasiveness has made this technique suitable even for unstable slopes and rock cliffs monitoring applications [39]- [41]. In addition, by comparing surveys performed in different times, it is possible to infer the displacement occurred during the period between different acquisitions [42].…”

“…On the contrary, within monitoring in an urban environment each object can independently move and thus it is essential to discern a target to one another. A similar integrated use of GBInSAR and TLS technologies for monitoring purposes has been already proposed in the case of mountain flanks [13], urban sites [39], and cultural heritage sites [20].…”

Ground-based synthetic aperture radar interferometry (GBInSAR) remote sensing technique has been repeatedly proved an effective tool for monitoring built environment affected by structural and geological criticalities. In this paper, it is described how this technique can be successfully applied for early-warning procedures and detection of ongoing deterioration processes on archeological and cultural heritage sites. An integrated approach of GBInSAR and terrestrial laser scanner (TLS) technologies was performed on Volterra test site (Tuscany, Italy), where a sudden collapse of a 35-m wide section of city walls occurred on January 31, 2014. The installed early-warning monitoring system is capable of an accurate and focused realtime displacement detection of the south-western side of the city including walls, buildings, and monuments, thus allowing prompt interventions for citizens safety and conservation purposes. The effectiveness of this alert technique became evident when the precursors of a second impressive wall collapse were clearly detected. From the beginning of the GBInSAR monitoring, we measured a constant displacement velocity of 0.1 mm/h in correspondence to a 15-m high wall sustaining the Acropolis and lying an underground parking. After a sudden increase of velocity values up to 1.7 mm/h, the local authorities were alerted so that they had time to interdict the area to citizens and to take adequate safety countermeasures two days before the collapse.

“…A more innovative remote sensing approach is the use of Ground Based InSAR (GB-InSAR) [Tarchi et al, 2003;Pieraccini et al, 2006]. These systems can be operated in periodic mode, with repeated operatorbased surveys, or in semi-continuous mode, by deploying permanent GNSS receivers, ATS and GB-InSAR devices in the field and by controlling data acquisition, data processing and data transmission cycles using dedicated computing units and broadband connectivity.…”

This paper discusses critical issues related to the reliability of topographic monitoring systems such as ATS (Automated Total Stations), GNSS (Global Navigation Satellite System) and Ground Based InSAR focusing the attention on controlling the stability of networks infrastructure, which have influence on data correction procedures but are often taken for granted, and on integrating results in GIS (Geographic Information System), under a common reference framework and with respect to open-access ancillary data. The novelty of the paper lies in the demonstration of the efficiency obtained by a proper implementation of the system. Discussion makes reference to an active landslide by using ATS, GNSS and Ground Based InSAR in continuous and periodic mode.

“…a variety of geomatic techniques may be used, going from the most effective established techniques (use of RT GNSS receivers, Total Station and levelling surveys when applicable ) to the most innovative ones like SAR interferometry (Pieraccini et Al., 2006) Airborne Laser Scanning, remote sensing. All of them present some critical aspects and strengths as far as landslide monitoring applications are concerned.…”

ABSTRACT:In order to define a methodology that faces the major critical issues, we used a Terrestrial Laser Scanner to monitor a large landslide that caused significant disruptions both to an important state road and to a major railway line in Italy. To survey the landslide we used three different models of Terrestrial Laser Scanners, including a "full wave form" one, potentially useful for filtering vegetation from the data. The output of each measurement campaign is a Digital Surface Model referred to a unique reference system. Starting from the DSMs we produced the Digital Terrain Models, one for each survey. The use of different models of TLS together with the software packages recommended by the companies for data processing, allowed us to compare the surveys and to evaluate the reliability and the accuracy of results. The comparison of data has been useful in order to identify and analyse over time the areas of greatest deformation and the directions of landslide movement and it also gives us some elements about the validity of the technique in this kind of applications. The laser surveys have shown a strong dynamic of the slope but have also highlighted some difficulties in order to efficiently filtering the data. Using two different kinds of TLS, full wave form and mono eco, on the same portion of landslide allows us to make comparisons between the two methodologies for landslide monitoring in a real-world context.
