The Interferometric Point Target Analysis (IPTA) technique and Advanced Synthetic Aperture Radar (ASAR) images acquired over Hong Kong from 2007-2008 were used to detect ground deformation in the urban area of Guangzhou city in South China. A ground deformation rate map with scattered distribution of point targets shows the maximum subsidence (rise) rate as high as -26 to -20 mma(-1) (16-21 mma...
Extended abstract Introduction The vital need for river management is understood and predicts bank erosion processes. River bank erosion is one of the sediment major sources for many rivers across the world. Bank erosion is a key process in fluvial dynamics, affecting a wide range of physical, ecological and socio-economic issues in the fluvial environment. These include the establishm...
As the Internet develops into a more powerful cyberinfrastructure (the Grid), Geological Survey knowledge will enter a framework where users assess its value by its relevance and evaluated reliability rather than its source, and artificial boundaries of place and discipline lose significance. Within Geological Surveys, much effort has been devoted to the development of the geological map throug...
Using JERS-1 and PALSAR radar images provided by JAXA, we built regional and continental scale mosaics of Sahara that allowed to discover major geological features. The unique capability of L-band SAR to map subsurface structures in arid areas revealed several impact craters and paleo-rivers in
