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.
AVIRIS TASK MANAGEMENT
