RESUME In this paper, an advanced technique for the generation of deformation maps using SAR (Synthetic Aperture Radar) data is presented. The algorithm, called the Coherent Pixels Technique, estimates the linear and non-linear components of the displacement, the error of the Digital Elevation Model (DEM) used to cancel the topographic terms, and the atmospheric artifacts from a reduced set of ...

Structural health monitoring is a crucial issue in areas with different hazard sources, such as Italy. Among non-invasive techniques, remote sensing provides useful information supporting the management process and safety evaluations, reducing impact of disturbances on functionality construction systems. The ground displacement time-series based analysis Differential Interferometric Synthetic A...

Indonesia is undeniably true is one of the most disastrous country in the world when it comes to incidences of natural disaster. Besides its geologic setting of being squeezed by three major tectonic plates (Eurasian, Pacific and Indo-Pacific plates), its location in tropical region makes it also vulnerable in terms weather imposed disaster such as flood, landslides and typhoon. On the other ha...

Land subsidence is a natural or anthropogenic process triggering the settlement of Earths surface. When this phenomenon induced by groundwater withdrawal, compaction unconsolidated sediments causes land displacement. Differential Interferometric Synthetic Aperture Radar (DInSAR) widely used nowadays to monitor over extensive areas. However, validation DInSAR measurements with in-situ techniques...

This work is focused on deformation activity mapping and monitoring using Sentinel-1 (S-1) data and the DInSAR (Differential Interferometric Synthetic Aperture Radar) technique. The main goal is to present a procedure to periodically update and assess the geohazard activity (volcanic activity, landslides and ground-subsidence) of a given area by exploiting the wide area coverage and the high co...

The Differential SAR Interferometry (DInSAR) is one of the most powerful devices for monitoring deformation processes on the Earth surface. Here, a dataset of TerraSAR-X StripMap imagery covering almost the whole Crotone province territory, located in the south of the Italian peninsula, has been selected and processed. The time span goes from April 2008 to June 2010. In this work, two different...

Geologic Carbon Sequestration becomes an essential instrument which has been aimed for mitigation of global warming. More understanding of storage processes and assessing environmental, safety, and health impacts in the event of a leak to the atmosphere are certainly important. Therefore, monitoring is one of the answers enabling technologies for CO2 storage. It is expected to support multiple ...

The Advanced Land Observing Satellite (ALOS), launched on 24 January 2006, is a Japanese satellite carrying an L-band SAR sensor, namely the PALSAR, which is expected to demonstrate good performance in applications such as crustal deformation measurement, subsidence detection and landslide monitoring. This paper describes a case study of Differential Synthetic Aperture Radar Interferometry (DIn...

This paper is addressed to readers without advanced knowledge of remote sensing. It illustrates some current and potential uses of satellite Synthetic Aperture Radar interferometry (InSAR) for landslide assessment. Data acquired by SAR systems can provide 3D terrain models and be used to assist in regional scale investigations, e.g. aimed at evaluation of susceptibility of slopes to failure. Un...

In this paper, we propose an advanced methodology to perform three-dimensional (3D) Finite Element (FE) modeling to investigate the kinematical evolution of a slow landslide phenomenon. Our approach benefits from the effective integration of the available geological, geotechnical and satellite datasets to perform an accurate simulation of the landslide process. More specifically, we fully explo...
