Abstract :
The high resolution imaging spectrometer (HIRIS) designed for the Earth Observing System (Eos) is designed to acquire images in 192 spectral bands simultaneously in the 0.4-2.5-μm wavelength region. HIRIS is a targeting rather than a continuous acquisition instrument and obtains high-spatial- and spectral-resolution images in a 30-km swath with a 30-m ground instantaneous field of view (GIFOV) in vertical viewing. Pointing will allow image acquisition at -30° to +60° along-track and ±24° cross-track. The raw data rate of the instrument is 512 Mbs. The high spectral resolution will make it possible to identify many surficial materials such as rocks, soils, and suspended matter in water directly. HIRIS also offers the possibility of studying biochemical processes in vegetation canopies
