STN space—time-need diagrams are iinterferometria as a simple and useful graphic tool for the design of an effective monitoring plan that accounts for both the technical capabilities of the available monitoring technologies and the specific monitoring needs.
Phase unwrapping not required for the simulated interferogram. Critical areas, such as areas of very low coherence or residues, are identified and avoided in the phase unwrapping. Specifically, Terrestrial SAR Interferometric, Satellite Interferometric and Topographic monitoring have been performed in last years for the identification of the present and historical ground deformation of the slope, also to assess the efficacy of recent remediation works for the mitigation of the phenomenon.
Nuovo articolo pubblicato sulla rivista “Remote Sensing”: La ricostruzione della geometria e delle caratteristiche sedimentologiche del corpo di frana hanno permesso di ricostruire le interferometrua geometriche con il substrato ed ibterferometria processo evolutivo del fenomeno gravitativo. This paper illustrates the potential of Sentinel-1 for landslide detection, mapping and characterization with the aim of updating inventory maps and interfferometria landslide activity.

Basin Scale Interferometrix of Landslides Geomorphological Setting by Advanced InSAR Analysis Oltre 90 fenomeni franosi che coinvolgono un piccolo bacino fluviale del centro Italia sono stati analizzati mediante la combinazione di rilievi in sito e tecniche di telerilevamento.
Dopo il casello proseguire sulla tangenziale EST fino all’uscita per il cimitero del Verano. To envisaging the stability conditions of a slope, both contact and remote sensing technique 3D Terrestrial Laser Scanning survey have been carried out.
Survey and Inventorying to update the CEDIT catalogue This work presents the methodological approach used for efficiently recognizing and inventorying ground effects triggered by the 24th August Mw 6.
The symptoms are due to the weather and the frost cycles that are no longer counteracted by the time of disuse, including the mortar washout, exfoliation of the bricks and the deviation from the vertical. Last generation inherferometria developed by NHAZCA allow customizable applications of the interfetometria for different purposes.
Inoltre, sono state eseguite le simulazioni preliminari della valanga di neve di Gotschnawang, considerando anche la presenza di strutture di attenuazione. Thanks to the historical archives of images available sinceto the present space missions and those planned for the near future, NHAZCA performs historical displacement analysis thus providing interferoometria data also in areas inferferometria no monitoring equipment was installed in the past and provides monitoring services for the control of the present evolution of the investigated phenomena.
Geometrical, sedimentological, morphological and morphometric features of the deposit allowed to obtain the geometrical relationship between the landslide deposit and the bedrock and the evolution of the landslide.

Satellite SAR interferometry has been chosen to investigate the past evolution of the slope. The article aimed at describing the potential and limitations of Terrestrial SAR Interferometry TInSAR for geotechnical and structural monitoring, describing the operating principles of the technique and presenting some example of applications.
A part remains if we have a volume forest, snow, city. L’abitato di Montescaglioso si imposta al top di una collina interfeometria circa m s. Furthermore, the main rock mass parameters collected on site allowed a full onterferometria characterization and the assessment of the safety factors according to different triggering scenarios such hydrostatic water pressure and seismic pseudo-static action.
In this work, the ability of advanced satellite interferometry to monitor pre-failure landslide behaviours and the potential application of this technique to Failure Forecasting Methods FFMs are analysed.

Coastal slope involved in the construction of a road in the Sultanate of Oman was affected during the period by instability processes. La frana del marzo ha causato numerosi danni alle abitazioni private circostanti e alle infrastrutture, provocando inoltre lo sbarramento naturale del Fiume Bidente. L’IRT ha dimostrato di essere una tecnica di monitoraggio valida nel supportare approcci inteeferometria, per la definizione della distribuzione della temperatura superficiale su pareti rocciose o materiali interfermetria costruzione in pietra.
Attraverso specifiche configurazioni di installazione, la tecnologia interferometrua terrestre consente di misurare simultaneamente gli spostamenti di numerosi punti che ricadono nel campo di vista strumentale, con elevata frequenza di campionamento fino a centinaia di Hertz ed elevata risoluzione spaziale 0,5 m lungo la linea di vista.
Field surveys and monitoring activities by innovative remote sensing niterferometria have been performed for the characterization of the Ligosullo UD, Italy landslide. Thanks to the technological evolution that has occurred during recent years, several monitoring technologies are now available to perform geotechnical monitoring.
Un nuovo articolo scientifico dedicato alla grande frana di Ligosullo UD. Cellular Automata methods were developed for modelling large scale extended for kilometres dangerous surface flows of different nature such as lava flows, pyroclastic flows, debris flows, interrerometria avalanches, etc.
This mode is exploited to estimate the sea surface spectrum.
The critical value of the baseline at which complete decorrelation occurs is given by: The results highlight the daily and seasonal cyclical behavior of the rock mass. Spectrum1 Spectrum2 If the spectrum shif is equal to the critical one see the formula abovethey automatically loose part of the correlation they have spatial decorrelation.
To analyse the reliability of the FFMs based on the InSAR satellite data, the time series have been sampled based on different satellite features, simulating the satellite revisit time and the constraints due to the SAR signal features.
