Introduction to Hyperspectral Imaging page 2 Before Getting Started It may be difficult to identify the important points in some illustrations without a color copy of this booklet. You can print or read this booklet in color from MicroImages’ web site. The web site is also your source for the newest Getting Started booklets on other topics. You can download an installation guide, sample data, and the latest version of TNTlite. http://www.microimages.com For much of the past decade, hyperspectral imaging has been an area of active research and development, and hyperspectral images have been available only to researchers. With the recent appearance of commercial airborne hyperspectral imaging systems, hyperspectral imaging is poised to enter the mainstream of remote sensing. Hyperspectral images will find many applications in resource management, agriculture, mineral exploration, and environmental monitoring. But effective use of hyperspectral images requires an understanding of the nature and limitations of the data and of various strategies for processing and interpret- ing it. This booklet aims to provide an introduction to the fundamental concepts in the field of hyperspectral imaging. Sample Data Some illustrations in this booklet show analysis results for a hyper- spectral scene of Cuprite, Nevada. This scene was acquired using the Airborne Visible/Infrared Imaging Spectrometer (AVIRIS), which is operated by the NASA Jet Propulsion Laboratory. The same scene is used in the exercises in the com- panion tutorial booklet Analyzing Hyperspectral Images . You can download this scene in the TNTmips Project File format (along with associated sample data) from the MicroImages web site or contact MicroImages to obtain the data on a free CD-R. More Documentation This booklet is intended only as a general introduction to hyperspectral imaging. In TNTmips, hyperspectral images can be processed and analyzed using the Hyperspectral Analysis process (choose Raster / Hyperspectral Analysis from the TNTmips menu). For an introduction to this process, consult the tutorial booklet entitled Analyzing Hyperspectral Images . Additional back- ground information can be found in the booklet Introduction to Remote Sensing of Environment (RSE) . TNTmips ® and TNTlite ® TNTmips comes in two versions: the professional ver- sion and the free TNTlite version. This booklet refers to both versions as “TNTmips.” If you did not purchase the professional version (which requires a hardware key), TNTmips operates in TNTlite mode, which limits object size and does not allow preparation of linked atlases.

Hy- perspectral remote sensors, on the other hand, collect image data simultaneously in dozens or hundreds of narrow, adjacent spectral bands. These measure-
