SpectralUtils

This is a package for basic manipulation of imaging spectroscopy data. It is designed to accomodate data from a variety of instruments, abstracting out the specifics of the file delivery. Currently, the package supports data from the following instruments / product levels:

• AVIRIS-3 L2A Reflectance
• AVIRIS-NG L2A Reflectance
• EMIT L1B Radiance
• Any data in ENVI format

Utilities

A series of utility scripts are provided to help with common tasks, such as:

Standard RGB, with stretching
