 About Us  Other Resources Spatial Resolution  How does MISR
view the ground?  MISR Typical Camera Configurations  Each MISR
camera sees instantaneously a single row of pixels at right
angles to the ground track, -- we call it a "pushbroom" imager
because of the way it sweeps along the ground track. MISR
collects data only on the daylit side of the Earth. During each
orbit, MISR obtains a swath of imagery that is 360 km wide by
about 20,000 km long.  What is the reason for the swath width?
Changes in the reflectance of Earth's surface during the
vegetation growing season are observable on weekly time scales.
In accordance with this, the selected MISR viewing swath width
of 360 km allows viewing
