MEaSUREs Antarctic Grounding Line from Differential Satellite Radar Interferometry, Version 2

This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, provides 22 years of comprehensive high-resolution mapping of grounding lines in Antarctica from 1992 to 2014. The data were derived using differential satellite synthetic aperture radar interferometry (DInSAR) measurements from the following platforms: Earth Remote Sensing Satellites 1 and 2 (ERS-1 and ERS-2), RADARSAT-1, RADARSAT-2, the Advanced Land Observing System Phased Array type L-band Synthetic Aperture Radar (ALOS PALSAR), Cosmo Skymed, and Copernicus Sentinel-1.

See Antarctic Ice Sheet Velocity and Mapping Data for related data.

This is the most recent version of these data.

Version Summary: 

In Version 2, the temporal coverage now includes 22 years from 1992 to 2014. In addition, the data format changed to shapefiles.
