Hyperion on EO1

Question 1

Into what general category of EOS does the instrument fall?

Hyperion EO1 falls in the Hyperspectral EOS category

Question 2

What capture technology is used?

Pushbroom capture technology is used. It has a single telescope and two spectrometers, one visible/near infrared (VNIR) spectrometer (with CCD detector array) and one short-wave infrared (SWIR) spectrometer

Question 3

Is the sensor active or passive?

The sensor is passive

Question 4

At what wavelength(s) does the sensor function?

220 unique channels. VNIR (70 channels, 356 nm - 1058 nm), SWIR (172 channels, 852 nm - 2577 nm)

Question 5

What resolution does the sensor have – temporal and spatial?

Temporal

Question 6

Is the sensor carried on an airborne or spaceborne platform? What is that platform – typically?

Spaceborne-EO1

Question 7

Who developed/launched/manages the sensor?

Nasa developed Hyperion but it is operated by Goddard Space Flight Center, and managed by Chris Stevens.

Question 8

Can data be purchased from service providers?

Yes - from USGS

Question 9

What products are available?

Data products consist of imagery collected during the original one-year technology demonstration/validation mission, as well as more recent collects from the subsequent EO-1 Extended Mission period to date.

· Level 1Gst is terrain corrected and provided in 16-bit radiance values. The data are available in Hierarchical Data Format (HDF) or Geographic Tagged Image-File Format (GeoTIFF) and are distributed on DVD and File Transfer Protocol (FTP).

Question 10

At which main application areas is the sensor aimed?

The uses for an instrument that can make such fine spectral distinctions include studies of land use, changes in land cover, mineral resource assessment, research into coastal processes, changes in the atmosphere and more.
