Chapter 18
From this simple pilot study, it has been decided to develop a much more
extensive study involving a wide range of data (including data sets from
video systems, airborne scanners, Polder, ATSR and AVHRR) and analytic
tools, which is now underway at CSIRO. For example, the testing
methodology now also involves using Ridge and eigenvalue analysis to
examine correlations between the kernels and the effects this introduces.
This study will be reported and its findings may help in the development of a
“global” BRDF typology in the future.

ACKNOWLEDGEMENTS
Norm Campbell’s group in Perth, especially Harri Kiiveri, Fiona Evans
and Suzanne Furby have developed a systematic testing process from which
the results quoted here form a small part. Fred Prata, Denis O’Brien and
Ross Mitchell have supplied data, knowledge and activity for this EOC
Thread activity as have Vanessa Chewings, Peter Hick and Cindy Ong from
their extensive holdings of video data of many land covers and many Sun
and view angles.
