AVIRIS Organization and Tasks
The AVIRIS (Airborne Visible/InfraRed Imaging Spectrometer) project provides calibrated data from an airborne sensor to customers in NASA, NOAA, EPA, USGS, academia, and industry. The AVIRIS project is catagorized as follows:

Generate Scientific Knowledge (GSK) Domain
Design and Conduct Experiments Process
Procedure for Airborne Experiments


The technical approach to delivering AVIRIS spectral image data is provided in the structure below with the specific activities listed.
