We applied an image correlation method to the Japanese Earth Resources Satellite-1 (JERS-1) synthetic aperture radar (SAR) data obtained from 1996 to 1998. The obtained ice flow velocity was systematically larger on the western streamline than on the eastern streamline from the grounding line towards the downstream region. The differences were 0.28 km/a in 1996 and 0.33 km/a in 1998, which were significantly...
This study aims to use ICESat /GLAS data for correction of DEM made from Interferometric SAR data instead of traditional ground control points (GCPs) collected by ground survey. GLAS is a laser altimeter system and it can measure the earth surface topography with ultimate vertical accuracy (plusmn14 cm) and high spatial accuracy (plusmn15 m). Therefore, we can treat GLAS data for the reference of...
