#### Description

This dataset provides complete land ice and ocean
classification masks at 15 m for the Greenland ice sheet.
Ice cover was mapped using
a combination of orthorectified panchromatic (band 8)
imagery from the Landsat 7 Enhanced Thematic Mapper
Plus (ETM+), distributed by the USGS, and RADARSAT-1
Synthetic Amplitude Radar (SAR) amplitude images produced
and distributed by I. Joughin at the Applied Physics
Laboratory, University of Washington.

The Landsat imagery was acquired for the months of July
through September in 1999, 2000 and 2001 (mostly 2000)
and the RADARSAT imagery was acquired in fall of 2000.
