Abstract
The GonioExp06 field campaign from 19th to 24th of June 2006 is part of a strategic initiative to improve bio-geo-chemo-physical parameter estimation from optical remote sensing data. The focus of the research is on the investigation of the directional fraction of hyperspectral data, emphasising the value adding effect of directional information as supplement to the well known spectral one. Three field goniometric systems (FIGOS, MGS and AIS A gon) of different design, an extensive accompanying measurement campaign and simultaneous multidirectional data takes by Proba/CHRIS (space) and ROSIS (airborne) are combined to create the data base necessar y to investigate the radiative transfer between the surface and the sensors and to contribute improving physical modelling and inversion techniques. The application focus is the “precision” domain in land use (agriculture, forestry, nature conservation).
