Analysis of Classified Imagery for Glacier Change in the McMurdo Dry ValleysEntry ID: McMurdo_Glacier_Change_01
Abstract: Classified material was used to remotely determine glacier extent in
the McMurdo Dry Valleys of Antarctica. A secondary goal was to
monitor the extent of ice-covered lakes. Because changes in glacier
extent are slow in the polar environmnent of the dry valleys, I
resorted to classified material because of its greater spatial
resolution over commerically available products. Of particular
importance is the archive of material going back 30 years in time.
Material was found for several different years that were suitable for
this analysis and the extent of glaciers and lakes are compared to
recent SPOT imagery.
Application has been made to release an imagery derived product for
public distribution and examination.
