HyMap Airborne Hyperspectral Scanner

The HyMap Imaging Spectrometer is an Australian development, built by Integrated Spectronics Ltd.,
and operated by HyVista Corp. The sensor originally is dedicated to mineral exploration.
Environmental monitoring is gaining a vital importance for its application.

The system is realised as a whisk-broom scanner with an ax head double mirror. In four individual spectrometer
units the wavelength range between 400 and 2500 nm is covered in 125 spectral bands with a
bandwidth of approx. 16 nm.

The instrument offers an extremely high signal to noise ratio (SNR) of more than 500:1 which is more
than most existing imaging spectrometers including AVIRIS can realise.

These facts make HyMap a very valuable instrument for the simulation of future spaceborne
spectrometers which as well will have a similar noise characteristic. Further specifications include: 5 m
spatial resolution; 60 degrees swath width on-board radiometric and spectral calibration 3 axis gyros
stabilised platform.

DLR is promoting the use of the HyMap in Europe and participated in the
PROSMART'98 and '99 Campaigns which were conducted in the frame of the SmartSPECTRAL
initiative of Dornier Satellitensysteme (DSS)
