InSAR grounding lines

Description

This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, provides 17 years of comprehensive high-resolution mapping of grounding lines in Antarctica, derived using differential satellite synthetic aperture radar interferometry (DInSAR) data from the Earth Remote Sensing Satellites 1 and 2 (ERS-1 and ERS-2), RADARSAT-1, RADARSAT-2, and the Advanced Land Observing System Phased Array type L-band Synthetic Aperture Radar (ALOS PALSAR) for years 1994 to 2009. Parameters include latitude, longitude, sensor, and up to four orbits and respective dates.
