Data Set Abstract |
The natural form of imaging spectrometer data is the spectral
image cube. It is normally in band sequential format, but has a
dual nature. It is a series of 'images' of the target,
each in a different wavelength, in ascending order. It is also a
set of spectra, each at a particular line and sample, over the
target area. Each spectrum describes a small portion of the area.
When transformed into cubes, the data may be analyzed spatially,
an image at a time, or spectrally, a spectrum at a time, or in
more complex spatial-spectral fashion. |
