In this study, we developed a new SAR/InSAR-based land-cover classification algorithm for estimating surface roughness, a key parameter that is critical for accurate compound flood modeling. We successfully classified the Greater Houston area and New Orleans into nine classes with distinct surface roughness using L-band ALOS PALSAR-1 data.

Advances in interferometric synthetic aperture radar (InSAR) in earth system science
Progress in Physical Geography: Earth and Environment, 2009During recent years, synthetic aperture radar (SAR) interferometry (InSAR) has become an important tool for precise measurements of the earth’s surface topography and deformation. This paper presents an overview on recent developments in InSAR applications, with emphasis on the use of satellite-borne sensors for applications in geoscience, topographic

Since the early 1990s, sinkholes and wide, shallow subsidence features (WSSFs) have become major problems along the Dead Sea shores in Israel and Jordan. Sinkholes are readily observed in the field, but their locations and timing are unpredictable. WSSFs are often difficult to observe in the field.

Tianjin is one of the cities in the north of China where the land subsidence has most seriously developed. The land subsidence has been lasting for 50 years. In the paper, we use permanent scatterers interferometric synthetic aperture radar (PS-InSAR) technique to detect and measure ground movement in this area.

Interferometric synthetic aperture radar (InSAR) is capable of measuring ground-surface deformation with centimeter-to-subcentimeter precision at a spatial resolution of tens of meters over a large region. With its global coverage and all-weather imaging capability, InSAR has become an increasingly important measurement technique for constraining magma

The availability of a near-global digital elevation model derived from the Shuttle Radar Topography Mission (SRTM) provides archeologists a new tool to complement other remote sensing data. SRTM data not only provide basemaps for geographic information systems and aid in geometric corrections, they also provide data for visualizations and animations ...

One of the most critical stages in height reconstruction from Synthetic Aperture Radar (SAR) interferometry is the two-dimensional phase unwrapping stage. The observables, i.e. the gathered complex radar data, are characterised by a measurable phase between 0 and 2, whereas the true phase of each sample, directly related to the propagation path of the
