of ASTER and SPOT-5 DEM’s for the ice sheet periphery and margin
(i.e. below the equilbrium line elevation) south of
approximately 82.5°N, and AVHRR photoclinometry in the ice sheet
interior and far north (Scambos and Haran, 2002).
SPOT-5 DEM’s were produced and distributed as part of the Spot5
stereoscopic survey of Polar Ice: Reference Images & Topographies
(SPIRIT) project (Korona et al., 2009). Ocean surfaces were masked
using the GIMP Land Classification mask and replased with the
CNES CLS11 mean sea surface height (Schaeffer et al., 2012).

\nVersion 2.2
This Digital Elevation Model (DEM) is constructed from a combination
of ASTER and SPOT-5 DEM’s for the ice sheet periphery and margin
(i.e. below the equilbrium line elevation) south of
approximately 82.5°N, and AVHRR photoclinometry in the ice sheet
interior and far north (Scambos and Haran, 2002).
