Hyperspectral Task: Inter-Related Activities for High Quality Data Acquisition and Research

This working group investigates the feasibility of hyperspectral research and develops outcomes through a sequence of activities. The objectives include developing solutions for instrument calibration, establishing a field spectroscopy program, generating a high-quality base of hyperspectral data, and seeking collaboration opportunities. The Millenium Workshop aims to streamline data collection and reporting, address instrument deficiencies, and allocate resources effectively. The visit from NASA/TRW provides support for Australian sites and opportunities for scientific collaboration and instrument loans.

Presentation Transcript

  1. Thread: sequence of activities from acquisition, through base processing, interpretation and finally to product presentation Working Group: 'committee' type of activity with a specific time-frame that investigates feasibility and develops or specifies outcomes

  2. Task: A modular component, often short-term (one to three years)

  3. The Thread therefore is Hyperspectral Task Hyperion Activities Inter-related & supporting activities

  4. Hyperspectral Task Objectives The Hyperspectral Working Group concluded that: even though HS research was being undertaken in a number of CSIRO divisions, "common" access to high quality hyperspectral data was lacking and coordination and collaboration between the HS research groups was warranted.

  5. Hyperspectral Task Objectives (cont) Work with other EOC Task areas to develop solutions to generic research issues associated with instrument calibration, data reduction including geometric modelling and normalisation for atmospheric and BRDF effects plus general field instrument deployment and use Work with other EOC Tasks to develop an effective Field Spectroscopy Program to establish standardised measurement protocols, a base of instruments and help train EOC members to ensure high quality calibration and validation activity for missions

  6. Hyperspectral Task Objectives (cont) 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 use and evaluation of Spectral Library methods and their effectiveness in environmental unmixing

  7. Hyperspectral Task Objectives (cont) Use the base of EOC HS data to establish & develop algorithms for a specified range of applications, which reflect the investment in sites & field campaigns. These will be from among geological, tropical & temperate vegetation, coastal & estuarine waters & rangelands applications. Seek external & international collaboration in the EOC site activities as well as collaboration in hyperspectral missions in Australia & coming satellite opportunities such as Hyperion, ARIES, CHRIS, and NEMO

  8. Lessons Learned People Instruments Protocols Data  Products

  9. Millenium Workshop Combine the needs and interests of a number of EOC threads and tasks.

  10. Millenium Workshop (cont) Field Work Address field procedures and the collection of data. Cross calibrate instruments and highlight any deficiencies in data collection and processing

  11. Millenium Workshop (cont) Workshop An opportunity to discuss procedures and techniques with colleagues A semi formal approach to the data reporting and review of documentation. Highlight and address differences in the results obtained by various instruments

  12. Millenium Workshop (cont) Major Planned Outcome Draw attention to areas where extra resources will need to be allocated to help streamline data collection, processing and reporting.
