4.6 GER DAIS-2815
Geophysical Environmental Research built an ASTER
Simulator for Japan Geophysical Institute in 1992. That
instrument has three spectrameters: 700 - 1000
nanometers with a 300 nanometer bandwidth, 3000- 5000
nanometers with three, 600 nanometer bandpasses and
8000 to 12000 nanometers with 20, 200 nanometer
bandpasses. The instrument has a variable IFOV ranging
from 1.0, 2.5 and 5 milliradian.
4.7 GEOSCAN
In 1984, an Australian company, GEOSCAN PTY. LTD,
began development of a prototype MKI airborne
multispectral scanner with 24 spectral bands. Currently,
GEOSCAN has developed an advanced hyperspectral
imager with up to 48 spectral bands. The instrument uses
three spectrometers: 500 - 850 nanometers with 20-71
nanometer bandpasses (32 channels) 2050 - 2500
nanometers with 60 nanometer bandpasses (8 channels)
and 8000 to 12000 nanometers with (6 channels). The
GEOSCAN MK II can make hyperspectral measurements
from 10-meter GIFOV's over a 10,000 meter swath. The
GEOSCAN instruments have been extensively used by
industry for mineral exploration in the western United
States, South America and Australia.
4.8 CASI.
In 1988, the Canada Center for Remote Sensing undertook
development of the Compact Airborne Spectrographic
Imager (CASI). CASI can acquire 15 bands in imaging
mode or 288 spectral bands in radiometer mode. Its
spectral range is from 430 nanometers to 870 nanometers
and it has 3 nanometer bandpasses. CASI has 578
pixels/line and can achieve 5 meter spatial resolution
depending on the flight height above terrain.
4.9 CCRS SWIR Full Spectrum Imager (SFSI)
The Canada Center for Remote Sensing (CCRS) has
developed a hyperspectral imager called the SWIR Full
Spectrum Imager (SFSI) which detects solar reflectance
from 1220 to 2420nm in 22 to 115 bands. The system can
simultaneously acquire the full spectrum at 10.4nm
bandpass spectral resolution. Ground instantaneous fields
of view can range from 50 cm to 4 meters over a swath of
up to 2km. In June 1995 the SFSI acquired extensive data
over mineral deposits in Nevada.
4.10 Daedalus Airborne Thematic Mapper (AADS)
The Daedalus Airborne Thematic Mapper is an 11 channel
scanner that acquires seven Thematic Mapper bands to
simulate TM data. There are 5 bands in the visible, 3
bands in the near-infrared, two bands in the short-wave
infrared and one band in the thermal infrared. This sensor
has been used by several exploration firms to acquire
higher spatial resolution data than Landsat.
4.11 DAEDALUS MIVIS
In 1993 Daedalus Enterprises of Ann Arbor Michigan
developed the Multispectral Infrared and Visible Imaging
Spectrometer (MIVIS). That instrument was developed
692
from the mineral exploration and environmental
assessment communities. It has four spectrometers: 430 -
830 nanometers (20 channels with 20 nanometer
bandwidths), 1150 - 1550 nanometers (8 channels with 50
nanometer bandwidths), 2000 - 2500 nanometers (64
channels with 8 nanometer bandwidths) and 8200 - 12700
nanometers (10 channels with 500 nanometer bandwidths).
4.12 HUGHES Wedge Imaging Spectrometer (WIS)
The Santa Barbara Research Center (SBRC) of Hughes
Aircraft Corporation developed a Wedge Imaging
Spectrometer (WIS). The WIS can collect 126 spectral
bands of data with bandpasses of 6 nanometers to 20
nanometers. The entire instrument can easily fit in a
container 6 inches by 10 inches in size.
4.13 HUGHES HYDICE Hyperspectral Imager
In 1993 the Hughes Danbury Optical Systems began
development of the Hyperspectral Digital Imaging
Collection Experimental Sensor (HYDICE). This sensor is
collecting 210 spectral bands with bandpasses ranging
from 2nm to 14nm over a spectral range of 385nm to
2500nm. The system provides 1meter to 3 meter spatial
resolution over a 500m to 2km swath. The radiometric
resolution is 12 bits.
4.14 NASA ASAS
Beginning in 1987, NASA Goddard Space Flight Center
began developing an Advanced Solid-State Array
Spectrometer (ASAS). This instrument is unique in that it
can acquire data on the ground at seven different viewing
angles. ASAS has 62 bands in the 400-1060nm region of
the spectrum and with 11.5 nm bandwidth.
4.15 French ISM
The ISM was built by the Observatorie Paris-Mendon, the
Institut d'Astrophysique Spatiale and the Department
d'Etude Spatiale. It has 64 bands in the 800-1700nm
region with 12.5nm bandwidth and 64 bands in the 1500-
3000nm spectral region with 25.5 bandwidth.
4.16 German ROSIS
ROSIS is the Reflective Optics System Imaging
Spectrometer developed by MBB, DLR and GKSS. |t has
128 spectral bands from 450-850nm and bandwidths of
5nm.
4.17 China MAIS
The Shanghai Institute of Technical Physics has been
developing the Modular Airborne Imaging Spectrometer
(MAIS). It uses three individual spectrometers.
Spectrometer | is a Silicon linear array and covers the 440-
1008nm region with a 20 nm bandpass for 32 bands.
Spectrometer Il is a PbS linear array and covers the 1500-
2500nm region with 30nm bandpasses for 32 bands.
Spectrometer IIl is a HgCdTe linear array and covers the
7800-11800nm spectral region with a spectral resolution
varying from 400 to 800nm in 7 bands. The MAIS is flown
on a Cessna Citation aircraft at an altitude of 3000 meters
and has a ground resolution of 12 meters at nadir. The
