This 3-D image of Mt. Everest was processed by the Centre for Remote
Imaging, Sensing and Processing (CRISP) from a stereopair formed by
combining a SPOT-5 image and a SPOT-4 image. The SPOT-5 image was
acquired on 2 October 2002, and the SPOT-4 image on 4 October 2002.
Their incident angles were 1.8° and 23° respectively.
The geometric processing (bundle adjustment) was carried out using a
SPOT 5/4 camera model software developed in CRISP. The horizontal
control (XY) was provided by holding the SPOT-5 camera model fixed;
while the height control is derived from various high peaks with known
heights in the vicinity (including the Mt. Everest height at 8848m). The
DEM’s and SPOT-5’s draped 3-D perspective view was then generated by
SOCET SET ® software.
