ENVI provides an extremely powerful, innovative, and user-friendly environment to display and analyze images of any size and data type. With ENVI everyone can use the available data. With all the features you would expect, like registration, classification, contrast enhancement, filtering, transforms, map composition and production. Dynamic overlay capabilities allow toggling of both gray scale and color images in linked windows for quick comparison of image features. When an input file is opened, each band is put into a list and is then available to all system functions.
Bands can be of disparate data types and have identifying names associated.
With multiple input files open, the user can easily select bands from different files to be processed together. Advanced visualization tools allow selection of image spectral endmembers in n-Dimensional space. No image processing package can satisfy everyone's needs. That is why ENVI is offered as a turnkey application and development version. The development version offers easy customisation of ENVI due to the powerful underlying IDL language - making it easy to create the specific function you need or create a complete custom solution based on the ENVI structure.
