ENVI 3.6 includes new data access tools, correction tools, change detection capabilities and a host of other improved infoimaging features for extracting information from radar, panchromatic, multispectral, hyperspectral, thermal and other types of digital image data. New features available in the software include data access tools for reading imagery from sensors aboard the European Space Agency’s ENVISAT satellite, ImageSat International’s EROS A1 satellite, and the SPOT 5 satellite. New correction tools for radiometrically calibrating DigitalGlobe’s QuickBird satellite data and georectifying SPOT imagery from satellite ephemeris information have also been added. Multiple display options allow users to choose among several display window configurations, and change detection tools for both thematic and grayscale imagery are also available. Spectral tools provide new classification, sharpening, and hyperspectral analysis capabilities, while improved mosaic preview display provides realistic image thumbprint views. The software is available on Windows 98/NT/2000/XP, Mac OS X, Linux and UNIX.
