ENVI 4.2
ENVI 4.2 software is used for the visualization, analysis and presentation of all types of digital imagery. Version 4.2 introduces progressive geospatial information technologies to the remote sensing, intelligence and military communities, and includes tools for autoregistration, geospatial statistics, log residuals and vegetation analysis. The Autoregistration tool automatically identifies tie points between two images for pixel-by-pixel analysis and classification, and is designed for use with images from multiple sensors, and for comparing images from different times.
