ENVI 4.0
ENVI 4.0 offers major enhancements over previous versions, including new image orthorectification tools, classification tools, mosaic color balancing, pan-sharpening algorithms and other features. The software is a remote sensing image analysis and image exploitation software tool that includes links to popular GIS software programs. The availability of high spatial resolution imagery from the QuickBird and IKONOS satellites, coupled with the software’s new functionality, provides enhanced capabilities for precisely locating objects of interest within an image, and perform tasks such as change detection and image sharpening with higher accuracy than was previously possible.
