— A new field goniometer system (FIGOS) is introduced that allows in situ measurements of hyperspectral bidirec-tional reflectance data under natural illumination conditions. Hy-perspectral bidirectional reflectance distribution function (BRDF) data sets taken with FIGOS nominally cover the spectral range between 300 and 2450 nm in 704 bands. Typical(More)
A physically-based model to correct atmospheric and topographically induced illumination effects in optical satellite data is developed and tested. Special emphasis is put on the impact of rugged terrain. Ground reference data for various land use classes enables the assessment of the corrections' influence on land use classifications. The estimation of(More)
