Description

This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, provides comprehensive high-resolution mapping of grounding lines in Antarctica from February 1992 through November 2025. The data were derived by applying differential satellite synthetic aperture radar (SAR) interferometry (DInSAR) to SAR data acquired by various space-based platforms.

See <a href="https://nsidc.org/data/measures/aiv">Antarctic Ice Sheet Velocity and Mapping Data</a> for related data.

Version Description

For Version 2, temporal coverage was extended through 2014. In addition, the data format changed to shapefiles.
