The Image Visualization and Infrared Spectroscopy (IVIS) Facility is comprised of three labs designed to function as a state-of-the-art image analysis, infrared spectroscopy and GPS resource. Currently, the image analysis lab contains approximately 2.0 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 three HP duplex color laser printers. A complete graphics station is powered by a new MacIntosh iMac Core2 Duo computer with a large format scanner, a Nikon LS-2000 35mm Film Scanner, and a Polaroid ProPalette 7000 Film Recorder.

The planetary image 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, ITT 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 spectroscopy lab 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. A new addition is the ability to collect emission spectra at temperatures up to 1600 C. Field-based data equipment includes: a forward-looking infrared (FLIR) S40 thermal camera; an ASD Fieldspec HH VNIR field spectrometer, two Panasonic Toughbook laptop computers for field image processing and equipment operation; a Trimble differential GPS Pathfinder Pro XRS unit with two different Laser Tech 3-D profiling systems (long and short range); a Raytek Raynger MX 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).
