Viper Tools
The original Viper Tools website (www.vipertools.org) is no longer operational, but VIPER Tools can be downloaded here. There are two versions of VIPER Tools: 1.5 and 2.0. Only Version 1.5 currently has a manual, but one is in the works for Version 2.0. Version 1.5 will only work with ENVI 4.8 or lower and Version 2.0 requires ENVI 5.1 or higher.

Introducing VIPER Tools
The VIPER Tools software package is an ENVI add-on that provides a suite of processing tools for multiband passive optical remote sensing data including hyperspectral and multispectral imagery. The major components of the software are tools for creating and managing spectral libraries, for selection of optimal endmembers for Spectral Mixture Analysis (SMA) and for calculating and interpreting SMA and Multiple Endmember Spectral Mixture Analysis (MESMA).
Installation (for details see manual):
Within the distribution path for ENVI, locate the ‘save_add’ folder. Make a subdirectory named ‘VIPER’ in this folder. Unzip the archive file using the appropriate software and save the files to the newly created ‘VIPER’ folder. In order to run Viper Tools, make sure run classic ENVI+IDL.
