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.

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; 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. Software includes all the major GIS and remote sensing packages (Arc/Info and Arcview, ERDAS Imagine, ERMapper and ENVI/IDL).
