The Image Visualization and Infrared
Spectroscopy (IVIS) Laboratory is designed to function as a state-of-the-art
image analysis, infrared spectroscopy and GPS laboratory. Currently, the lab
contains approximately 1.5 terabytes (TB) of disk storage housed on an online RAID
disk array and managed by Sun Ultra-10 Sparc workstation/server (dual OS - Solaris
8/Win2000), two Sun Blade 100 workstations and two Dell Dimension 4550 computers.
Peripherals include numerous CDROM and DVD readers/writers, an Exabyte tape drive, and
an HP duplex color laser printer. A complete graphics station is powered by a MacIntosh
G4 computer and contains a large format scanner, a Nikon LS-2000 35mm Film Scanner, and
a Polaroid ProPalette 7000 Film Recorder.
The lab archives an extensive collection of NASA airborne and spaceborne visible near
infrared (VNIR), short wave infrared (SWIR) and thermal infrared (TIR) data for many
locations throughout the western US, Hawaii, and Alaska, as well as the TIR data from Mars.
Image processing and analysis is carried out using a variety of in-house software packages,
as well as ERDAS Imagine, RSI ENVI, and the full suite of Adobe and Corel software. The
IVIS facility is now coordinating and archiving data for several major objectives of the
ASTER instrument onboard the Terra spacecraft (including global data of active
volcanoes, urban centers, and deserts).
The laboratory houses a Nicolet Nexus 670 FTIR spectrometer with the
capability to collect concurrent reflectance and emissions spectra over the 0.4 - 25 micron
wavelength region. The spectrometer is used to collect data of soil, rock, vegetation
and man-made samples to aid in the quantitative compositional analysis of remote sensing
data. Field-based data equipment includes: a new forward-looking infrared (FLIR) S40
thermal camera; two laptop computers for field image processing and equipment operation; a
Trimble differential GPS Pathfinder Pro XRS unit with a Laser Tech 3-D profiling system; an
Exotech hand-held radiometer; as well as Nikon photographic equipment.
Within the Department of Geology and Planetary Science is the
Geographical Information
Systems (GIS) and Remote Sensing (RS) teaching laboratories. They both serve as teaching
facilities, but are open and available to department personnel. The GIS Lab contains ten Dell
Dimension and five Gateway workstations. The RS Lab includes ten Sun Ultra-10 dual-OS systems
(Solaris/Win2000) workstations, a Sparc Ultra-2 dual-processor server with 1.3 GB RAM and a
400 GB disk array, a large format plotter/printer, and miscellaneous I/O hardware. Software
includes all the major GIS and remote sensing packages (Arc/Info and Arcview, ERDAS Imagine,
ERMapper and ENVI/IDL).
