Monitoring structure health of urban bridges with advanced multi-temporal InSAR analysis

Structural Health Monitoring of Urban Infrastructures with Time-Series InSAR Analysis

The intensive urban infrastructures including roads, subways and high-speed railways are closely related to the sustainable economic development and social stability, and also supporting spatial distribution of various functions within the city. To ensure the security and sustainable development of transportation, we evaluated the potential of high resolution time-series Interferometric Synthet...

Monitoring Cultural Heritage Sites with Advanced Multi-Temporal InSAR Technique: The Case Study of the Summer Palace

Cultural heritage sites are rare and irreplaceable wealth of human civilization. The majority of them are becoming unstable due to a combination of human and natural disturbances. High-precision, efficient deformation monitoring facilitates the early recognition of potential risks and enables preventive diagnosis of heritage sites. In this study, an advanced Multi-Temporal Interferometric Synth...

Multi-temporal InSAR analysis of Wenjiagou Landslide using Distributed Scatterers

Urban monitoring using multi-temporal SAR and multi-spectral data

In some key operational domains, the joint use of synthetic aperture radar (SAR) and multi-spectral sensors has shown to be a powerful tool for Earth observation. In this paper, we analyze the potentialities of combining interferometric SAR and multi-spectral data for urban area characterization and monitoring. This study is carried out following a standard multi-source processing chain. First,...

Small Temporal Baseline Subset Analysis (stbas): an Insar Technique for Multi-temporal Water Level Monitoring in Wetlands

We present an InSAR technique called Small Temporal Baseline Subset (STBAS) for monitoring absolute water levels time series using radar interferograms acquired successively over wetlands. We tested the STBAS technique with two-year long Radarsat-1 data acquired over the Water Conservation Area 1 (WCA1) in the Everglades wetlands, south Florida (USA). The fine beam SAR data were acquired succes...
