“…The process of PS-INSAR is briefly explained in Fig. 1 [9]. In addition to normal work flow, all SLCs were oversampled with a factor of 2 and noisy interferograms were eliminated to increases PS density [11].…”

“…It analyzes a long stack of SAR images in a relatively small subset of pixels and extracts those points with stable backscattering behavior over time. These points are called persistent scatterers (PS) [8].It is efficient for surveying due to its advantages of high accuracy, time and cost effective, does not require in-situ measurement and large area coverage [9]. The downside is that natural PS points are rare in dense vegetation [2].Stanford Method for Persistent Scatterers, StaMPS, is a software package that computes PS points by spatial correlation of interferogram phase [10].…”

Gunung Pass is a landslide-prone area located in Cameron Highland District of Malaysia. In this paper, land deformation in Gunung Pass is monitored by using Stanford Method for Persistent Scatterer Interferometric Synthetic Aperture Radar (StaMPS) of TerraSAR-X data and theodolite surveying. TerraSAR-X data were used. Time series plot of StaMPS is shown and compared with the theodolite surveying reading on the corresponding dates. The study found a considerably similar trend of both methods.

Synthetic Aperture Radar (SAR) is a potential application of remote sensing to geological and hydrometeorological hazards. This paper presents sustainability strategies for smart cities: the use of SAR Sentinel-1 for monitoring flood inundation and landslide hazards in Aceh Province, Indonesia. In this study, for flood detection, we attempt to uses Sentinel-1A (S-1A) in the same direction and acquisition through polarization of Vertical transmit and Vertical received (VV) – Vertical transmit and Horizontal received (VH) with a temporal baseline of 6 days. Those data were then analysed using the SNAP Toolbox. The results showed that the S-1A was successfully for detecting a flood inundation in which VH polarization is more sensitive than VV. For landslide monitoring, we apply multitemporal SAR images, where one of them is the Quasi-Persistent Scatterers (Q-PS) technique. Using ascending and descending orbit pass results in a better velocity map where both sides of the slope are detected due to the different sensor angle of both orbital passes. This technique has resulted in the undulating areas being monitored well and this will also fill the gap of layover and shadowing phenomena of the slant range SAR image. The Q-PS combinations were very effective to identify the deformation features associated with the land movement. For a smart city, natural hazards such as landslides and floods require continuous monitoring to ensure the potential as well as management and mitigation of natural hazards. Therefore, the InSAR technique is one of the effective ways for doing this strategy.
