GLIMPS

GLIMPS is a free tool for image analysis and rectification. It includes an ENVI file viewer for image browsing and extraction of spectra.

Image Analysis Features ENVI File display including various scaling options, multispectral/hyperspectral easy band selection, export of scaled image to GIF/JPG/TIFF/PNG, image profiles (x,y) and spectral profile (Z profile), export of spectral profiles to spectral libraries, coordinate linking support, cube rectification to arbitrary resolution, extent, and rotation, pseudo color display of single band imagery and indices, scale to exact range of single band imagery, spectral band index calculation (Band Ratio, NDVI, ARVI, Absorption Depth), spectral classification (image based/SLB based) using spectral angle or spectral fit, spectral library display (ENVI file format), statistics calculation to spectral library.
