This data set is part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, and provides a map of Antarctic ice shelves and the Antarctic coastline. The map is assembled from 2008-2009 ice-front data from ALOS PALSAR and ENVISAT ASAR data acquired during International Polar Year, 2007-2009 (IPY), and the InSAR-based grounding line data (MEaSUREs Antarctic Grounding Line from Differential Satellite Radar Interferometry, NSIDC-0498) augmented with other grounding line sources. NOTE: These data are considered provisional pending a review by the MEaSUREs program.
