Knowing more about ASTER images:
The ASTER instrument consists of three
separate instrument subsystems. Each subsystem operates in a different spectral
region, has its own telescope(s), and was built by a different Japanese
company. ASTER's three subsystems are: the Visible
and Near Infrared (VNIR), the Shortwave Infrared (SWIR), and the Thermal Infrared (TIR). To find out more about each module click on the item of
interest.
In the present relation were integrated only the bands
corresponding to the Visible and Near Infrared portion of the electromagnetic
spectrum, as described below.
The VNIR subsystem operates in three
spectral bands at visible and near-IR wavelengths, with a resolution of
