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)
