Comparing DInSAR and PSI Techniques Employed to Sentinel-1 Data to Monitor Highway Stability: A Case Study of a Massive Dobkovičky Landslide, Czech Republic

open access: yesRemote Sensing, 2019
Single-pair differential synthetic aperture radar interferometry (DInSAR) as well as more advanced methods, such as persistent scatterer interferometry (PSI), allow vertical displacements to be detected at the sub-centimeter level.

Change detection in SAR time-series based on the coefficient of variation

open access: yes, 2019
This paper discusses change detection in SAR time-series. Firstly, several statistical properties of the coefficient of variation highlight its pertinence for change detection. Then several criteria are proposed. The coefficient of variation is suggested

Sentinel 1 and 2: Searching for Physical Image Content [PDF]

open access: yes, 2013
ESA’s upcoming Sentinel-1 and Sentinel-2 missions open new perspectives for the application-oriented use of SAR and/or optical multispectral images. We expect short and regular revisit times as well as easily available and well documented products with ...

Estimating Snow Depth Using Multi-Source Data Fusion Based on the D-InSAR Method and 3DVAR Fusion Algorithm

open access: yesRemote Sensing, 2017
Snow depth is a general input variable in many models of agriculture, hydrology, climate, and ecology. However, there are some uncertainties in the retrieval of snow depth by remote sensing.

Sentinel-1 InSAR measurements of surface elevation changes over yedoma uplands on Sobo-Sise Island, Lena Delta [PDF]

open access: yes, 2018
Yedoma is vulnerable to thawing and degradation under climate warming, which can result in lowering of surface elevations due to thaw subsidence. Quantitative knowledge about elevation changes can help us better understand the freeze-thaw processes of ...

Assimilation of SAR and optical data into an agro-meteorological model for monitoring yield of corn [PDF]

open access: yes, 2016
This study aims to assess the contribution of SAR and optical satellite images to estimate corn biophysical parameters and crop yield at field scale. Satellite data are assimilated into a simple agro-meteorological model named SAFY-WB (Simple Algorithm ...
