Integration of the kernel and referencing approaches

In order to improve the level of understanding of the effects of bi-directional reflectance an investigation commenced to determine how well kernel models can be used to describe the BRDF effects calculated using the referencing method.

Two DMSV images (seen in Figures 45 and 48) were obtained using the CSIRO Wildlife and Ecology (DWE) system on 28.09.95. These images, across fairly uniform cover, were supplied to CMIS in unrectified form with auxilarily aircraft positioning information. The reference Landsat TM data, acquired on 27.09.95, was geo-rectified to the raw DMSV images and residual images were extracted for the two DMSV images. These image were also supplied to CMIS

It is expected that the raw and residual images will be analysed and a report delivered by CMIS and will then be included at this point.
