Staggered CCD
Configuration
The ground resolution can be improved by staggered CCD-lines
(Figure 4). They do
include 2 CCD-
lines shifted half a
pixel against the
other, so more
details can be seen in
the generated images.
Because of the over
Figure A.3.2: mixing of staged and in moving
direction over sampled information to higher
resolution image
sampling, the information contents do not correspond to the linear
double information. For SPOT 5 the physical pixel size projected
to the ground is 5m, while based on staggered CCD-lines the
super-mode has 2.5m GSD. By theory this corresponds to the
information contents of an image with 3m GSD.
