Objectives of the Hyperspectral Task

 

This task was established in July 1998 following recommendations by the EOC Hyperspectral Working Group. This group concluded that even though hyperspectral (HS) research was being undertaken in a number of CSIRO divisions, "common" access to high quality hyperspectral data by EOCrew members was lacking and that coordination and collaboration between the HS research groups was warranted. Hence, much of the emphasis of the objectives (below) deals with acquisition and management of HS and ancillary data.

 

The task HS objectives are:

Work with other EOC Task areas to develop solutions to generic research issues associated with hyperspectral instrument calibration, data reduction including geometric modelling and normalisation for atmospheric and BRDF effects plus general field instrument deployment and use (part of the Hyperspectral Thread Activity).

Work with other EOC Tasks to develop an effective Field Spectroscopy Program (FSP) to establish standardised measurement protocols, a base of instruments and help train EOC members to ensure high quality calibration and validation activity for missions.

Carry out a set of field/airborne campaigns over selected sites to generate a high quality base of hyperspectral data for research in EOC and Australia. The data are to include effective site and ancillary information combined with the hyperspectral data in raw and processed formats and documented to provide a sound base for innovative R&D.

Develop a HS spectral library for a wide range of uses and evaluation of Spectral Library methods and their effectiveness in environmental unmixing.

Use the base of EOC hyperspectral data to establish and develop algorithms for a specified range of specific applications, which reflect the investment in sites and field campaigns. These will be from among geological, tropical and temperate vegetation, coastal and estuarine waters and rangelands applications.

Seek external and international collaboration in the EOC site activities as well as collaboration in hyperspectral missions in Australia as well as coming satellite opportunities such as Hyperion, ARIES, CHRIS, and NEMO.
