VIFIS on TERN
Question 1
Into what general category of EOS does the instrument fall?
Hyperspectral
Question 2
What capture technology is used?
Pushbroom
Question 3
Is the sensor active or passive?
Passive
Question 4
At what wavelength(s) does the sensor function?
Shortwave, near-infrared and visible. 144 spectral bands of information from 419-862 nm.
Question 5
What resolution does the sensor have – temporal and spatial?
Temporal
Non-applicable as the instrument is airborne
Spatial
Depends on the flying height
Question 6
Is the sensor carried on an airborne or spaceborne platform? What is that platform – typically?
Airborne platform, installed in the nose of the UAV
Question 7
Who developed/launched/manages the sensor?
Manufacturer is the University of Dundee, Launched by BAI Aerosystems Inc. on behalf of NASA
Question 8
Can data be purchased from service providers?
No
Question 9
What products are available?
Unrectified image data for 114 bands of the same ground coverage
Question 10
At which main application areas is the sensor aimed?
Mapping of variations in ground or marine cover for agriculture, oceanographic, ecological or forestry studies
List 2 specific projects, where they have been reported, their goals and their outcomes.
This system was used to investigate the opportunities to analyse both spectral and angular reflectance data to monitor water and nitrogen stress in potato canopies and evaluated a range of simple sensors for this purpose. (Jones, 2004)
From a test programme conducted at NASA GFSC Wallops flight facility the feasibility of using an uninhabited aerial vehicle, a hyperspectral imaging instrument, and a portable data link system to retrieve Earth resources data was investigated (Nasa, 2002)
