Digital SAR Mosaic and Elevation Map of the Greenland Ice Sheet
Entry ID:
NSIDC-0052
Summary
Abstract:
The Digital SAR Mosaic and Elevation Map of the Greenland Ice Sheet CD-ROM combines the most detailed synthetic aperture radar (SAR) image mosaic available with the best current digital elevation model. The mosaic image shows both the location of the ice edge and the distribution of melt-related 'scatterers' on the surface. These scatterers include ice lenses and complex layered structure in the ...

Quality
The accuracy and precision of the DEM is not adequate for the detection of real ice surface elevation changes over time, and thus the DEM should not be used for such purposes. Additional processing would be necessary before the DEM could be used as part of a scheme for elevation change detection.
Access Constraints
This data set is available for non-profit, research-oriented purposes only. Prospective users of the product are required to complete a Research Agreement stating that the image and elevation data will be only be used under the specified terms and conditions.
