The Impact of the Structure and Composition of Shrub-Coppice Dune Landscapes On MASTER Reflectance Anisotropy
This study assesses the effects of physical structure and composition of shrub-coppice dune landscapes on anisotropy in the NASA MODIS-ASTER Airborne Simulator (MASTER) solar channels, and investigates the viability of simulating multi-angular data sets using off-nadir airborne imaging radiometry from a single overpass by means of data segmentation. Segmentation data are plant density and cover and spectral measures derived from high-resolution aerial photography and classified Landsat 7 Enhanced Thematic Mapper imagery. The directional signal contributes a variation of 5-10% in reflectance, necessitating angular corrections. For most areas the signal appears to differ only slightly with changes in landscape structure and composition because the view/illumination geometry is poor and reflectance is dominated by bright soils. Further work is required to determine whether simple models would be adequate for angular corrections.
