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.
Data are available via FTP in ASCII text (.txt) format.
Note: These data are considered provisional pending a review by the MEaSUREs program. Once the data have been reviewed, this statement will be removed from this documentation.
